Abstract

The effect of seasonal variation on ischolar_maining potential of Neem by using mid-cuttings, hardwood cuttings and epicormic shoots was studied at Biotechnoloty Research Centre (A.P. Forest Department), Triupati. The plant harmones such as IBA, IAA, 2.4-D were used alone or in combinations of different concentrations viz., 1000, 2000, 3000 ppm tested in both summer and winter seasons. Roots were observed in all types of branch cuttings after 30 days. During summer (April-May) 95 per cent of ischolar_maining was observed in epicormic shoots when treated with 1000 ppm IBA. However, in mid- and hardwood cuttings only 50% ischolar_maining was observed. During winter season (Nov.-Dec.) the epicormic shoots resulted in 50 per cent of ischolar_maining only. The individual concentrations showed better results as compared to combinations. Higher percentage of ischolar_maining was observed in summer compared to winter season.

Abstract

The International Provenance trial of Casuarina equisetifolia was established in 1996, with 27 provenances in Regional Forest Research Centre, Rajahmundry, East Godavari District, Andhra Pradesh. The Australian Tree Seed Centre of CSIRO, Canberra, Australia coordinated in collection of seed throughout the natural range as well as from land race populations of Casuarina. The Analyses of Variance of data indicated significant difference among provenances for height, GGL, GBH and straightness a











































p=0.05level of significance, while axis persistence has showed no significant difference. Genetic analyses showed heritability estimates for the characters axis persistence and straightness (below 15%) while moderate estimates of heritability for height, GGL and GBH (between 40.60%). It is suggested that selections could be made from superior trees of individual provenances in order to have broad base for genetic improvement of Casllarina equisetifolia in Andhra Pradesh.

Abstract

The International Provenance Trial Plot sponsored by FAO/DANIDA in collaboration with Andhra Pradesh Forest Department was established in 1973 at Maredumilli, North-East Andhra Pradesh, with 10 seed sources and one local seed source as control. The Analysis of Variance of data on 26 year old trees indicated non-significant differences among provenances for height, clear bole height, gbh, Crown scores while significant differences for survival rate, straightness and roundness of stem and health characteristics. Height and GBH growth of provenances ranged from 14.33 to 22.33 m and 42.80 to 69.78 cm and were comparable to site quality II/III reported for Teak in India. Among the indigenous seed sources 'Konni' (Kerala) and exotic sources 'Ban Mae Pan' (Thailand) were the best for all the parameters studied. Genetic Analysis showed low heritability (broad sense) estimates for the characters on height, gbh, health, crown and branching characters (below 30 per cent), while moderate to high estimates of heritability for straightness (32.85 per cent) and roundness of stems (39.46 per cent) and clear bole height (60.50 per cent) characters. It is suggested that selections could be made from superior trees of individual provenances in order to have a broad base for genetic improvement of Teak in Andhra Pradesh.

Abstract

Fertilisation of forest soils with chemical fertilisers is not only expensive but also results in environmental pollution. Therefore, it has become essential to go for a cheaper, natural, effective and environmentally safer resources such as biofertitisers. About 95-99% of soil phosphorus occurs in fohns that is not directly available to plant ischolar_mains. Further, its mobility in soils is very low. In such conditions mycorrhiza through symbiotic association offers an effective and long lasting remedy by solubilising unavailable phosphorus and converting them into available form, thereby acting as 'biofertilisers'. Pisolithus tinctorius is an ectomycorrhizal fungus living symbiotically with the ischolar_mains of Eucalyptus. Fruiting bodies of Pisolithus tinctorius were collected from different places and different strains were isolated. Axenic cultures were established on solid and liquid MMN media. From the axenic culture, mycobeads were prepared and applied to the Eucalyptus seedlings. Uninoculated seedlings were maintained as control under identical conditions to compare the growth the biomass. The fungal infected seedlings have better growth and ischolar_main development.

Abstract

Stumps of different girth classes of Bhadrachalam clone-l of Eucalyptus tereticornis of the same age were selected and coppiced. The coppice shoots were collected four times, each at 15 days interval separately from each of the girth classes and counted. It was observed that with the increase in the girth of the coppiced stump, the number of shoots produced per stump increased significantly. However no significantly differences were observed between the harvests. Thus it can be concluded from this study that the ability to produce coppice shoots may, in some way be related to the size of the donor tree, which may be due to increased coppicing ability or due to greater carbohydrate reserves in stumps of greater girth.

Abstract

An experiment was conducted at Srinivasavanam Field Research Station, Tirupati, India to find out whether the position of the rejuvenated shoot on the Eucalyptus stock plant exerted any influence on the ischolar_main and shoot growth of cuttings. The results revealed that the area of the largest leaf, percentage of sprouting buds, ischolar_main length, fresh weight and moisture content of ischolar_mains showed significantly higher values in respect of cuttings taken from coppice shoots of coppiced stump 7-13 cm above the ground. On the contrary, survival percentage, number of shoots, number ofleaves and number of ischolar_mains per cutting did not differ significantly among the treatments. Hence it is ideal to harvest the juvenile coppice shoots from 7-13 cm height on the coppiced stump to produce good quality clones.

Abstract

Advancements in Biotechnological research has opened up new avenues for rapid multiplication of forest trees. The paper presented here on micropropagation of sandalwood has described various experiments conducted during the last decade in our laboratory. The tree sandalwood has proved to be a very versatile material for tissue culture research. Success has been achieved in regenerating plantiets from somatic embryos differentiated from callus tissues originating from hypocotyl, stem and protoplasts cultures. Plantlets could be regenerating from synthetic seeds prepared by encapsulating somatic embryos in a proper matrix. Viable plantlets were recovered from somatic embryos grown in a bioreactor.

Abstract

The leaf oil of certain trees of Eucalyptus hybrid bas been shown to contain a very high percentage of cineole (63.2-72.3%). In this respect and also in almost all other characteristics the oil compares favourably with the Australian Eucalyptus globulus oil and very much more with the Indian Eucalyptus globulus oil. This particular strain of the hybrid can, therefore, be an additional source for the medicinal eucalyptus oil, with the added advantage that the trees can grow successfully under diverse conditions of climate, soil and rainfall.

• Studies on Sandal Spike Incidence of the Spike Disease Versus the Major and Minor Nutrient Status of the Soils of Sandal Growing Regions

Abstract

A study of the major and minor nutrient status of the soils of spike-affected and spike-free sandal growing regions has shown that deficiency of either the major nutrients, N,P,K and Ca, or the minor nutrients, Cu, Zn, Mn, Mo and Co in the soils of the spike-affected sandal regions is not serving as a pre-disposing factor for the onset of sandal spike disease. Khan and Yadav (1962) reported that calcareous soils with a low amount of available nutrients were related to the incidence of spike disease in sandal. The soils of the Mysore State are generally not calcareous in nature, but spike disease exists in many of the districts of the State. It has, therefore, given rise to a doubt as to whether the composition of the soil bas really anything to do with the incidence or otherwise of the spike disease in sandal. As long ago as 1955, Muthanna reported that application of minor elements did not show any remedial effect on the sandal affected by spike disease, thus showing that the latter is not traceelement deficiency disease. That the disease is not a deficiency disease is further proved by the fact that it is transmissible (Coleman, 1917; Sreenivasaya and Gopalaswami Naidu, 1928), while deficiency diseases are not. The question, however, remains as to whether the soil status is serving as a pre-disposing factor for the onset of the disease, though not the cause for it. Hence experiments have now been conducted with a view to settling this question, examining the soil samples from some of the districts of the healthy sandal areas (Bellary, Dharwar and Shimoga), and some of the districts of the spiked sandal areas (Kolar, Tumkur and Bangalore) in the Mysore State. From each of the districts, a suitable forest region was chosen, and soil samples were taken from two spots, collecting them from three different layers (0-25 cm, 25-55 cm, 55-85 cm) after clearing the surface soil. The analysis of the soil samples for pH, major nutrients (N,P,K and Cal and minor nutrients (Cu, Zn, Mn, Mo and Co) was done following the methods described by Jackson (1967) and Holmes (1945). Since the pH of the soils of the Mysore State ranges from 5.6 to 6.8 at which range the nutrients (major and minor) are well available, only the total status of these nutrients has been determined. The pH was determined at the moisture saturation percentage of the soils according to the procedure described by Jackson (1967).
