A study was conducted to assess seasonal distribution and infection intensity of ectomycorrhizae in Chir pine (Pinus roxburghii Sargt.). Maximum number of mycorrhizal ischolar_mains were observed to be highest during monsoon season (July, August and September). Dead mycorrhizal ischolar_mains were noticed to be maximum during summer. Per cent occurrence and death rate of mycorrhizae were observed maximum in the month of October. No specific patterns of increase and decrease of mantle thickness during various months were noted while the mantle thickness was found maximum in the month of October. The intensity of hartignet penetration was recorded maximum in the month of June and lowest in August. Overall, eight different types of mantle were observed in Chir pine forest. Positively significant correlation was estimated between available phosphorus and live mycorrhiza(P- Mycoflora Associated with Different Seed Sources of Pinus wallichiana

Vertical distribution of ectomycorrhizae in natural forests of Deodar (Cedrus deodara) and Chir pine (Pinus roxburghii) of Central Himalayas has been studied in relation to soil properties at various soil depths (0-30 cm). Soil moisture, pH, organic C. organic matter, total N and available P decreased along the soil depths in both of forest. Live, dead and total mycorrhizal counts were more in C. deodara and P. roxburghii. Highest numbers ofmycorrhizae were recorded between 6-10 cm depth. Apparently, a drastic change in mycorrhizae counts were recorded at soil depth below 15 cm significantly, (P- Bifussella saccata on Pinus wallichiana : a New Host Record from Himachal Pradesh

Experiments were conducted to standardize appropriate potting medium for raising Dalbergia sissoo seedlings under ischolar_main trainer seedling production system. In two different experiments , two kinds of potting media were tried , one with various combinations of sand , soil and compost and the other with charcoal , rice husk and compost. A multivariate approach was adopted considering the seedling quality parameters i.e. sturdiness , ischolar_main shoot ratio , ratio of fibrous/total ischolar_main biomass , Dickson quality index , and ischolar_main surface area , apart from the various growth and biomass traits of 3 month nursery growth. Dalbergia sissoo being a versatile and primary coloniser in riverine concession , came up very well in sand and compost combination (20% sand + 80% compost). However , it also performed well in other combinations of sand , soil and compost in the ratio of 1:1:3 ,1:0:4 and pure compost alone. In respect to the organic ingredients , combinations of charcoal , compost and rice husk in the ratio of 1:3:1 and 1:4:0 appeared satisfactory. Comparing the performance of both the types of potting media , it came to the notice that the sand , soil and compost combinations are fairly better for raising D. sissoo than the charcoal , rice husk and compost. The seedlings achieved significantly better growth , biomass and quality parameters when raised in sand , soil and compost than when raised in the potting mixture containing charcoal and rice husk. For the species like Dalbergia sissoo which is known to be a species of sandy alluvium soil , the ingredients like sand , soil and compost should be encouraged in the potting medium for raising in nursery.- Phalantha phalantha Drury (Lepidoptera : Nymphalidae) - a Major Nursery Pest of Poplar, Populus deltoides Bartr

Seedling quality is a key factor in the success of any tree plantation programme, which ultimately depends upon the ischolar_main system. Root trainers are increasingly being used to deal with the problem of ischolar_main coiling and distortion commonly encountered in polybag grown seedlings. Due to the lack of species specific results for Indian conditions and species, ischolar_main trainers are still at the initial stage of use in Indian nurseries. In the present investigation, a multivariate approach has been adopted to find out the right size/volume and type of ischolar_main trainer for raising Dalbergia sissoo seedlings in the nursery. Root trainers of various type and cell sizes like Hiko trays 90 cc, 150 cc, 300 cc, Book type 200 cc and single cell bullet type 290 cc were tried and the growth and biomass production of D. sissoo seedlings in 3 months time period was studied. The quality parameters of seedlings in various treatments were figured out. The seedlings raised under different size and type of ischolar_main trainers were also observed in the field for two consecutive years. Though the Hiko tray 300 cc cell volume scored maximum points in respect of seedling quality parameters upto the nursery stage, field performance of Hiko tray 150 cc volume was found the best. The Hiko tray 150 cc cell volume raised seedlings achieved maximum plant height and collar diameter after field planting although the performance of Hiko tray 300 cc and 150 cc cell volume was statistically at par in respect offield survival. The results have indicated that though the nursery stage growth performance has scored maximum points in respect of Hiko tray 300 cc cell volume due to greater space available for the ischolar_main system, the field performance of 150 cc volume is significantly better than the 300 cc one. Thus the Hiko tray 150 cc volume is the best size/volume and type of ischolar_main trainer for raising D. sissoo seedlings in nursery. The Hiko tray 300 cc volume comes out in the second category.- Standardization of Proper Volume/size and Type of Root Trainer for Raising Acacia nilotica Seedlings: Nursery Evaluation and Field Trial

Root trainers are increasingly being used to deal with the problem of ischolar_main coiling in polybag grown seedlings. However, the technology has not been standardized for most of the tropical tree species. In a multivariate investigation involving 5 type of ischolar_main trainers namely Hiko pots 90 cc, 150 cc, 300 cc, Book type 200 cc, and Single cell bullet type 290 cc, growth performance of Acacia nilotica seedlings was assessed on the basis of seedling quality parameters. The performance of the seedlings was also assessed in the field for two years.The seedlings raised in 300 cc Hiko pots performed the best in nursery as well as in the field. However, the performance of Hiko tray 150 cc cell volume and Single cell 290 cc appeared statistically equal with the Hiko tray 300 cc cell volume after two years field performance of seedlings. The results are indicative that, though Hiko trays 300 cc cell volume is the best size and type of ischolar_main trainer for A. nilotica, however, when there is a space constraint in nursery and the objective is to raise more number of seedlings per unit area of the nursery space, the Hiko tray 150 cc volume is equally good.- Selection of Proper Potting Mixture for Raising Acacia nilotica Seedlings under Root Trainer Seedling Production System

The containerized seedling production technology , especially the ischolar_main trainers , is dependent upon suitable growing media for raising quality seedlings in nurseries. Due to lack of species specific results for Indian conditions and species , the use of ischolar_main trainers is still in the initial stage. In the present investigation , experiments were carried out to findout the proper combination of sand , soil , compost and combinations of charcoal , rice husk and compost as a organic medium , to be used as growing media under ischolar_main trainers for raising A. nilotica seedlings. The growth , biomass production of Acacia nilotica seedlings in 3 months period was studied and the quality parameters of seedlings raised in various treatments (Potting mixture combinations) were figured out. In respect of sand , soil and compost , combination of sand and compost in the ratio of 1:4 (20% sand + 80% compost) produced the best results and scored maximum points in respect of quality parameters. Testing the organic ingredients , combination of charcoals and compost in the ratio of 1:4 (20% charcoal + 80% compost) was another good growing medium. Thus two potting mixtures with different ingredients were standardized. The results on use of pure compost as a potting medium were not very much appreciable. The compost is required to be supplemented with 20% charcoal or 20% sand for making it more effective in raising Acacia nilotica seedlings. Improper choice of potting mixture may result in poor quality seedling production in nurseries.- Ectomycorrhizal Status and Soil Characteristics of Deodar forest in Central Himalayan Region of Nainital Hills

Seasonal distribution of ectomycorrhizae in Deodar (Cedrus deodara) forest of Nainital hill of Central Himalayas has been assessed in relation to their soil characteristics. The occurrence of mycorrhizae in per 100g of soil was recorded to be highest in the month August and lowest in January. The per cent occurrence and attrition rate (live/dead) of ectomycorrhizae were also reported to be maximum in the month of August and minimum in January. Although no specific trend of increase and decrease in mantle thickness and Hartignet penetration was observed, however, the mantle thickness and Hartignet penetration were reported to be maximum in the months of November and May respectively. Linear regression between ectomycorrhizal counts and some of the soil characteristics have shown positively significant correlation (p < 0.001) between available P and live mycorrhizae. Negatively non-significant correlation was found between soil pH and total mycorrhizae. Moreover, positively significant correlation was observed between soil N and C : N with live mycorrhizae (p < 0.01) and that of P < 0.01 between soil moisture and live ectomycorrhizae.- Evaluation of Seed-Borne Fungi of Pinus roxburghii

Newly introduced five clones of Poplar (Populus deltoides Marsh) from Northern India to Central India, were studied for their leaf shedding and emerg.::mce behaviour during winter and spring seasons. The clones namely G-3, G-48, D-121 and S7-Cl remained in complete leafless condition for 2, 5, 7 and 6 weeks respectively. The leaf emergence in these clones started in first week of March and rapid leaf formation was recorded in subsequent weeks during March and April. The clone 65/ 27 has maintained its evergreen status under Central Indian conditions with minimum no. ofleaves during the months of January and February. These observations suggest the existence of a very short deciduous period in all the clones under Central Indian conditions. It has been further suggested that the deciduous condition has definite role in deciding the suitability of the clone under tropical conditions of Central India.- Study on the Pattern of Seed Germination of Various Subspecies Cum Provenances of Acacia nilotica Willd.

Seed germination pattern of 30 provenances belonging to 5 subspecies of A. nilotica namely tomentosa, indica var. jaquemontii, indica var. cuppressiformis, nilotica, and indica from 5 countries namely India, Sudan, Pakistan, Yemen and Senegal were studied in nursery conditions. Provenances of A. nilotica from Pakistan showed a very good performance and depicted a parabolic (asymptotic) type of germination curve. However subsp. indica var. cuppressiformis from Pune (Maharashtra, India) gave maximum percentage of seed germination (75%). Significantly a good correlation was evident between cumulative seed germination&number of days elapsed. Relative delay in the initiation of seed germination was found maximum in provenances of subsp. tomentosa and subsp. nilotica.- Occurrence of Loranthus Spp. On Oak in Kumaun Himalaya
