Indian Forester, Vol 134, No 1 (2008), Pagination: 125-130Abstract
Response of arbuscular mycorrhizal (AM) fungi, Azospirillum, phosphate-solubilizing bacteria (PSB) and a companion fungus (CF) (Aspergillus fumigatus) was studied on growth of Aonla (Emblica officinalis) in nursery. Application of AM fungi and PSB in combination produced maximum plant height followed by combination of all the four treatments. Maximum diameter of seedlings was obtained in Azospirillum treatment followed by Azospirillum along with the companion fungus, followed by combination of AM fungi and companion fungus and companion fungus and PSB. Maximum ischolar_main colonization was in AM fungi and companion fungus combination and combination of AM fungi, companion fungus and Azospirillum. On the basis of above application of AM fungi along with companion fungus or Azospirillum and companion fungus is recommended to boost the growth of Aonla in nursery.Keywords

Effect of application of biofertilizers, Azospirillum, phosphate-solubilising bacteria (PSB) and arbuscular mycorrhizal (AM) fungi was studied in a factorial experiment on production of planting propagules (stumps) of teak in nursery. Seed germination was maximum in Azospirillum treatment followed by its combination with AM and PSB after two months. Maximum height of seedlings was recorded in AM + Azospirillum, AM + PSB and AM+PSB+ Azospirillum combination after five months. Diameter of seedlings at collar region was maximum in AM, AM + Azospirillum and AM + Azospirillum + PSB combinations. The economics of biofertilizer application is also worked out. Application of biofertilizers increase the number of stumps produced per bed as well as the diameter of stumps. Therefore, an artificial profit index was calculated combining the both parameters to infer the real benefit of biofertilizers' application. Based on the profit index application of AM fungi along with Azospirillum was found the best treatment to produce quality planting propagules of teak in a commercial nursery.Keywords

The response of three different inocula of arbuscular mycorrhizal (AM) fungi was studied on growth, biomass, phosphorus (P) and nitrogen (N) uptake and per cent ischolar_main colonization in Bambusa nutans seedlings. The seedlings were raised as per routine nursery procedure in unsterilized soil mix. Mix AM inocula were used to inoculate the seedlings and comprised: (1) Acaulospora scrobiculata, Glomus mosseae, Scutellospora heterogama and S. pellucida, (2) Acaulospora sp. 2, A. scrobiculata, Gigaspora sp., Glomus mosseae, and Scutellospora pellucida, (3) A. laevis, Acaulospora sp., Gigaspora sp., S. pellucida. The first two inocula were isolated from bamboo ischolar_main segments and the third from teak rhizosphere soil. The improvement in growth parameters is correlated with per cent ischolar_main colonization of seedlings by AM fungi. Arbuscular mycorrhization by selected AM fungi constitutes in important approach for subsequent growth and development of Bambusa nutans seedlings.- Cultivation of Ganoderma lucidum (Fr.) Karst.

The extract of the fungus Ganoderma lucidum is used for treatment of joint pains, as elixer of life, good health and well-being. It is commercially cultivated in China, Japan, USA and Malayasia but so far it has not been cultivated in India. It has several host trees species in India and fresh isolates were obtained from infected ischolar_mains for taking up its cultivation. The results show that spawn and fruit bodies grown on chips and logs of Delonix regia are the best and in them those grown on chips, are still beter. Chips and logs of other species tried gave inferior results.- Biocontrol of Important Pathogens of Forestry Species by Streptomyces Formulation

Streptomyces sp. was isolated from soil and was screened in the laboratory for antagonistic activity against pathogens of forest tree species viz. Alternaria alternata ,Curvularia lunata , Sarocladium oryzae , Fusarium oxysporum , Ganoderma lucidum and Macrophomina phaseolina. On basis of laboratory studies , it was also tried to control the seed microflora of Albizia lebbek. Suitable formulation was developed after growing Streptomyces sp. in seventeen different substrates. Farm yard manure and chicken manure were found as the best substrates and they were found as the best carrier for this biocide. Streptomyces sp. was also multiplied in bulk by using lab fermentar in liquid PDA medium. The inoculum in bulk was prepared by using farm yard manure as the carrier for field application. Post emergence damping off diseases of A. procera , A. lebbek and D. sissoo were also controlled. The growth and biomass of these species were also enhanced by treatment with Streptomyces sp. The trial of Streptomyces sp. to control sheath blight disease of D. asper also gave good performance by encouraging the healthy culms. Trials of Streptomyces sp. in the present study exhibited successful control of differcnt pathogens as compared with the fungicidal treatments. The use of this bioagent was bencficial from pesticidal residue problems and also to safe guard the soil in nurscry and plantations. It is a self-multiplying species of Streptomyces in soil , which is antagonistic to a number of soil borne pathogens. It appears a new species of Streptomyces. It can be concluded that this Streptomyces sp. can be used to control the different pathogen which are responsible for causing seed borne diseases , ischolar_main diseases , damping off and leaf blight diseases in the nursery. The multilocational trials of the bulk cultures of this bioagent against ischolar_main pathogens are under trials.- Role of Storage Fungi in Germination of Strychnos potatorum Linn. f. Suppl.

Rhizoctonia bataticola caused severe charcoal ischolar_main-rot in tropical Pines of Orissa, India. Out of three species, surveyed Pinus caribaea was found more susceptible to this disease. Mortality rate was higher in hill top as compared to sloping and flat areas. Disease severity was noticed during hot and dry months. Bavistin or Dithane M-45 0.2 percent when combined with 0.2 percent KH2PO4 gave better protection to plants from ischolar_main-rot infection by M. phaseolina than when used alone. The antagonistic fungi G. virens and T. viride were also found effective in controlling this infection.- Fusarium Root Rot of Acacia nilotica and its Control

Fusarium pallidoroseum caused severe mortality of A. nilotica seedlings in nursery. It is one of the serious problems to developing healthy nursery stock. In order to manage this problem, VAM fungi, Rhizobium, Trichoderma viride and fungicides like Bavistin and Dithane M-45 were tried to control this disease. It has been found that biofertilizers like VAM fungi and Rhizobium along with antagonistic fungus T. viride were highly effective in controlling the ischolar_main rot problem of A. nilotica. This is recommended as the effective control to develop the healthy nursery stock for plantation.- Bacillus firmus as Bio-controlling Agent for Seed-borne and Nursery Pathogens of Forest Tree Species

Antagoistic bacteria were isolated from soil samples collected from different forest areas of Jabalpur, Mandla, Umaria and Bilaspur. One antagonistic bacteria Bacillus firmus was isolated from the soil of Belkund teak forest nursery, Kundam Project, Forest Development Corporation, Jabalpur. To study its effectiveness against pathogen associated with leguminous seeds eleven days old culture of B. firmus was applied to the the seeds of Albiziaprocera, A. lebbek, Dalbergia sissoo and Acacia nilotica and was compared with culture of the bio-agent Trichoderma viride and fungicides namely Indofil and Bavistin 0.2%. The seeds treated with the culture of B. firmus did not show any fungal flora during germination and at the same time per cent emergence of treated seedlings was also high. The suspension of B. firmus was also applied to one month old seedlings of A. procera and A. lebbek inoculated with Fusarium oxysporum causing post emergence damping off disease in these seedlings. The experimental finding shows that the seedlings of A. procera and A. lebbek inoculated with B.firmus did not show any mortality, which proved that the application of B. firmus could be used as bio-controlling agent against post-emergence damping off disease inforest nurseries.Keywords

Thirteen different provenances of Acacia nilotica were collected from different agroclimatic zones of India. Before sowing in the field, all the provenances were tested for seed mycoflora and germination. Large number of fungi belonging to different taxonomic groups were identified from seeds of A. nilotica. Aspergillus terreus showed the highest dominance in different provenances. The frequency of fungi was less in the provenances of Mandla and Jabalpur. A fungus Trichurus spiralis was recorded first time only on 6 provenances. The fungus was secreting the inhibitory substances, which possibly reduced the germination of seeds.Keywords

Phosphate solubilizingbacteria are known to play a major role in the solubilization of unavailable forms of soil phosphorus and uptake its native and applied forms. A total of 17 different Pseudomonas flourescens isolates recovered from rhizosphere and J.curcas, planted in different localities, were evaluated for their phosphatase activity in in vitro and in vivo conditions. Isolates viz., P#10, P#l1 and P#02 revealed maximum phosphatase enzyme activity and influence the maximum growth and therefore can be used as bioinoculant in nursery and field trials for better production of J.curcas.Keywords

Tropical pines are being increasingly used in pulp and paper industry and to meet their increased demand these are being raised in plantations. Exotic and indigenous plant species are seen to suffer from various diseases. Of these, damping off of Pinus caribaea in nursery beds can be controlled by drenching the soil mix with Blitox or Fytolan. Cercospora needle blight is seen affecting P.caribaea and P.roxburghiana. Fungicides Bavistin and Dithane can be applied during monsoon period to check spread of this disease. Lophodermimam needle fall is caused by various pathogens but the damaged caused is insignificant as the pathogens are rather weak. Diplodia die back in P.caribaea plantation was seen to affect poorly growing plants and is almost absent in vigorously growing trees. Charcoal ischolar_main rot in P.caribaea can be managed by modifying nursery practices such as weeding out leguminous weeds, avoiding intercropping, avoiding fertilizers during nursery stage, planting replacements in fresh pits, so that infection does not take place.- Role of Microbial Inoculants on Growth and Development of Jatropha Curcas in Field

Different microbial inoculants were tried to study their effect on the growth and development of Jatropha curcas L. All microbial (mix) inoculants showed response in enhancing the growth of J. curcas in terms of height and collar diameter. Microbial inoculation and mixed inoculation induced flowering while fruiting in 2nd year plants could be recorded only in AM and mixed inoculants of microbes. Though the fruit production was limited but could produce viable seeds. Experiments indicated that the microbial inoculants were more suitable for early flowering and fruiting. It is an important step for enhancing the productivity of this biodiesel plant.Keywords

Effect of ischolar_main exudates on AM colonization in Jatropha curcas was studied in the current work. Total three treatments were tested viz., ischolar_main exudates + AM fungi, AM fungi alone, and ischolar_main exudates alone. Out of which the treatment containing AM fungi + ischolar_main exudates showed maximum (75%) colonization followed by AM fungi alone. Impact on plant nutrient status was also observed and significant results were recorded. There was remarkable enhancement in phosphatase enzyme activity, phosphorus uptake and leaf protein in treatment containing AM fungi and ischolar_main exudates as compared to control. Therefore, from the present findings, it can be concluded that ischolar_main exudates affect the ischolar_main colonization of AM fungi which in turn improve the growth and development of biofuel plant J.curcas.Keywords

The growth performance of three bamboo species namely Bambusa bambos, Dendrocalamus strictus and Bambusa nutans was studied in four sites of agricultural fields. The sites II and III were more or less same in soil texture and nutrient status. The species of bamboo were inoculated with VAM fungi including Glomus mosseae, G. intraratices, Gigaspora species and Acaulospora species. The suitable control was maintained without VAM inoculation. Comparatively the response of VAM inoculation was better in site I. Bambusa bambos showed significant difference in the length of leading shoots compared with other two species of bamboo. Similarly the per cent infection was more in bamboo species planted in sites I, II and III. The spore population did not exhibit any significant variation in bamboo species inoculated and uninoculated (control) with VAM fungi.- Studies on Germination and Seed-borne Fungi of Some Forest Tree Species and their Control

The germination tests were performed with 4 different tree species in laboratory. The purity percentage and number of pure seeds per kg were also calculated. Lagerstroemia parviflora showed poor germination even from the fresh lots while other species showed high germination percentage. Over all 12 fungi were recorded in blotter as well as potato-dextrose-agar test which varies from species to species. Out of 4 fungicides used for seed treatment Bavistin, Dithane M-45 and Thyride @ 3 gm/kg seed weight were highly effective in controlling the seed myeoflora. It is recommended that the seeds of B. monosperma, D. strictus, L. parviflora and P. pinnata may be treated with the above light dose of fungicides for controlling fungal infestation.- Distribution of Vam Fungi in Bauxite Mine overburden Plantation of Amarkantak (Madhya Pradesh)

Arbuscular mycorrhizal (AM) fungi of Tectona grandis isolated from 20 different sites, including nursery, plantation and natural forests their ischolar_main colonization and effect of inoculation of AM fungi on growth of teak seedlings were studied. The per cent ischolar_main colonization ranges between 25-95 at different sites. Genetically superior (plus trees) showed heavy ischolar_main colonization as compared to other normal trees. Sixteen different AM fungi were isolated and identified belonging to 5 genera of Glom ales namely Acaulospora, Gigaspora, Glomus, Scutellospora and Sclerocystis. Among these Glomus etunicatum and Acaulospora scrobiculata were found most widely distributed species followed by Glomus indraradices and G. mosseae while G. fasciculatum, was found least frequent. Inoculation of teak seedling with G. fasciculatum and mix AM fungi separately showed better height growth, biomass and percent ischolar_main infection in nursery compare to uninoculated (control) seedlings. The mix AM inoculum is found more effective to boost the growth and biomass.- Effect of Inoculation of VAM Fungi and Rhizobium on Growth and Biomass Production in Acacia nilotica in Nursery

Seedlings of Acacia nilotica were inoculated with Rhizobium strain, isolated from nodules of the same species, VAM fungi and single dose of nitrogen and phosphorus in unsterilized soil in nursery condition. A single species of VAM fungus, Glomus mosseae and a mixture of VAM fungi locally isolated, consisting of Glomus species and a Gigaspora sp. Were used to inoculate the seedlings. Height growth, collar diameter, nodulation, percentage ischolar_main infection by VAM fungi, fresh and dry weights of shoot and ischolar_mains were determined after 4 months of inoculation. Inoculation of Rhizobium and VAM fungi and application of nitrogen and phosphorus singly or in different combinations enhanced the growth and biomass production as compared to uninoculated (control) seedlings. Maximum seedlings volume (height x ischolar_main collar diameter2) was found in seedlings inoculated with G. mosseae and Rhizobium in combination, as well as Rhizobium and phosphorus combination followed by mixed inoculum of VAM fungi. Maximum total dry biomass was recorded in seedlings treated with a combination of mixture of VAM fungi, Rhizobium VAM mixed and phosphorus. It is concluded that inoculation of VAM fungi, Rhizobium singly or in combination is equally or more beneficial over use of chemical fertilizers in raising the seedlings of Acacia nilotica.- Studies on Leaf Spot Disease of Calutropis Frocera Caused by Colletotrichum Dematium

The studies on needle blight disease caused by Cercospora pini-densiflorae in different provenances of P.roxburghii exhibited that there was no mortality in plants of Supkar (MP) origin and Rohri (HP) origin,whereas other provenance were highly susceptible to this infection. The heavily infected plants also exhibited a greater number of stomata and conidia in the needles. The size and septation of spores obtained from infected needles of different provenances also vary. The germination of conidia was very less or negligible in distilled water. The addition of glucose increased the higher percentage of germination. Bavistin and Dithane M-45 at 0.2 per cent concentration conSiderably checked the germination of different provenances under study. Fytolan at 0.2 per cent failed to check the germination but the germination was minimised to a considerable extent. On basis of the susceptibility of different provenances of p.roxburgii for C.pini-densiflorae it is recommended that the plants of Supkhar (MP) origin have developed a high tolerance to needle blight fungus as compared to other provenances. The plants of this origin may be used for plantation in Madhya Pradesh.- Possibilities for Enhancing the Fruiting in Teak Seed Orchards

The insecticide (Monocrotophos), hormones (Alpha Napthyl Acetic Acid) and Rallis tracel-2 (Micronutrient) were used in teak seed orchards at Behrai (Seoni, M.P.). The experiemental results showed that the growth promoting chemical and insecticides are not effective to increase the teak fruit production. Fruit dropping also does not appear to have been affected by these treatments. As the treatment applied within investigation failed to exhibit any positive correlation with the fruit production in teak and thus on older trees (about 10 years) these treatments should not be applied. The insect population can only be reduced to some extent by the treatment with insecticides only if it is beyond the tolerable level.- Effect of Some Soil Insecticides in Controlling the Major Insect Pests in Teak Nursery

Suitable control measures were devised for tackling the white ischolar_main grubs in teak nursery at Katanga (Balaghat, M.P.) and noticed that Basuddin (Diazinon) lOG @ 200g/bed (10m X 1m) followed by Phorate (Thimet lOG) 200g/bed was very effective against the white ischolar_main grub, H.serrata. In case of various doses of Phorate (Thimet) 10G, 200g/bed followed by 150g/bed was best among the other doses. In treated plots of BHC, Furadon and Sevin, the cumulative effect of larval population of teak defoliator, H.puera and skeletonizer, E.machaeralis, the observations confirm that Sevin 50 W.P. @ 200g followed by BHC 50 W.P. @ 600g/ bed was most effective against these pests.- Eucalyptus Litter Decomposition in Tropical Dry Deciduous Forest of Madhya Pradesh

Fungal decomposition of Eucalyptus litter in tropical dry deciduous forest was studied for three successive years. Succession of involved mycoflora and its frequency were noticed in two litter layers at quarterly intervals. Members of Phycomycetes, Ascomycetes and Basidiomycetes were the weak colonizers whereas the Deuteromycetes were strong colonizer showing better adaptability and higher percentage distribution. Intially the C/N ratio was wide but wben the succession took place, the C/N ratio of Eucalyptus litter gradually decreased below 20 and slightly increased in the later stages of decomposition (35.5/3.02). A wide range of humidity and temperature were suitable for litter decomposition.- Population Dynamics and Seasonal Abundance of some Forest Insect Pests (Nursery Stage) through Light Trap

Four concentrations viz. (0.005%,0.01%, 0.0125% and 0.02%) of monocrotophos (36 E.C.) were tested as contact and systemic action against the larvae of Atteva fabriciella in field and laboratory conditions at room temperature. On the basis of experimental findings 0.02% monocrotophos exhibited 80 and 100 per cent mortality within 24 and 48 hours in field condition. The same treated leaves from field when fed to third ins tar larvae in the laboratory condition gave 80 and 100 per cent mortality after 24 and 48 hours respectively. The leaves directly treated in the same conditions at room temperature also gave 100 per cent mortality after 72 hours. Atteva fabriciella may be successfully controlled by applying 0.02% monocrotophos.

A wide variety of fungal flora is involved during the process of natural weathering of teak fruit. Scytalidium sp. exhibited fast decomposition of epicarp from the fruit which resulted the completion of weathering of teak fruits within 21 days. The seeds extracted from such weathered lot through use of Scytalidium sp. exhibited high percentage of germination as compared with the other treatments. It is recommended that Scytalidium sp. can be used for fast weatherlng of teak fruits.- Cercospora Blight Disease of Melia azadirachta

The investigation and observations relating to sal mortality revealed a complex interaction between climatic parameters, physical soil attributes (soil compactness) converting the high forest into that of coppice origin and varied biotic factor. These factors have been responsible for the loss of plant cover and site deterioration resulting in the reduced tree vigour. The available data shows that insects and pathogens are not the primary factors responsible for all mortality. Their role is only secondary after the complex interactions of climatic, biotic and management factors have reduced the tree vigour. The causative factors could be summarised as has been given in a chart form (Fig 2).- Leaf Blight of Eucalyptus in Nurseries

The survey of charcoal ischolar_main-rot in Pinus caribaea caused by Macrophomina phaseolina (Tassi) Gold was conducted by random sampling technique in pine plantations of Bastar. The disease percentage was found to vary from compartment to compartment depending upon the land topography. Due to excessive run-off and lack of moisture on steep slopes as also under water logging conditions, the result of moisture stress causes maximum damage to plants on account of pathogen attack. Control measures have been suggested to prevent and minimize the disease menace in nursery and in plantation area.- The Studies on Nodulation Behaviour in Leucaena leucocephala

The nodulation behaviour in different age group of Leucaene leucocephala K-28 was studied in detail. The number of nodules considerably increased with age. The culture of rhizobium enhanced the height growth of the seedlings in laborotory and nursery conditions. The height growth and survival percentage of Leucaene seedlings in the field trial plantations were more when the seedling stock for plantation was used from seedlings grown in polythene as compared to those directly transplanted from nursey beds. The application of nitrogen fertilizer (area) in potted mixture supressed the nodule formation. It has been found that rhizobium inoculation can boost up Ibe growth of nursery stock of L. leucoctphala by producing a healthy stock of high vigour for large scale plantation of Leucaena in silvipastrol systems and social forestry programmes.- Studies on Charcoal Root Rot of Pinus caribaea

Macrophomina phaseolina (Tassi) Goid caused a serious charcoal ischolar_main rot disease of Pinus caribaea seedlings in nurseries and plantations in M. P. It was estimated that the seedlings of P. ctiribaea suffered a heavy loss due to this infection. The whole of the ischolar_main system was involved in the processes of infection by M. phaseolina which penetrated Ihe vascular cylinder of the seedlings and young plants. It was much likely that the translocation the solutes was disturbed. A large number of sclerotia were developed during the process of senescence of the seedlings which exhibited the sign of death of the plants. The disease was favoured by bot summer months. Some measures for the control of the disease were suggested. A review of existing literature indicated that this disease is being reported for the first time from India.- Studies on Fusicladium Leaf Spot of Pongamia pinnata

Fusicladium pongamae Syd. Caused severe foliage blight of Pongamia pinnata Pierre in nurseries. The symptoms, histopathology and pathogenicity of the organism were studied. There was heavy conidiation by the organism which germinated at appropriate humidity and temperature thereby infecting the healthy leaves. Sugars, organic acids and phenolics were observed chromotographically in healthy and the diseased leaves. The increase in the organic acid and phenolics was related with the mechanism of disease resistance during infection processes. Amongst the fungicides tried, bavistin, ziride and benlate were more effective in controlling the infection. Any of these fungicides may be sprayed at 0.2 per cent when the inoculum in the form of spores very less.- Development of Resistance and Enhanced Mineral Solubilization Capacity of Plant Growth Promoting Rhizobacteria (PGPRs) Native to Calcareous Soils of Lime Stone Mined Spoils
