Tree species performance trial was conducted on alkali soils with five tropical species. All the five tree species namely Acacia ferruginea, Albizia lebbek, Azadirachta indica, Emblica officinalis and Pongamia pinnata were found to grow well in alkali soils having the values of pH 9.4, ESP 33, Ece 8.1 dsm-1, CaCO3 5.7%. Among the five tropical tree species studied, maximum total biomass production (leaf, small branches, stem and ischolar_main) was observed in Acacia ferruginea and minimum in Emblica officinalis. High survival percentage (69-93%) in all the tree species showed better prospective for wastelands afforesiation and social forestry programmes to meet the energy demand as well as to maintain ecological balance and environmental stability.

Root initiation in Carallia brachiata, (Kierpa) terminal branch cuttings is studied by treating with Indole Butyric Acid (IBA) (2000 ppm), as quick dip and placing them under mist. Good results were obtained with respect to number of ischolar_mains and time taken for ischolar_main initiation at 2000 ppm concentration of IBA. This technique is useful in rapid propagation of the species which otherwise is a problem due to poor germination of the seed. Moreover greater genetic uniformity can be achieved in planting stocks by adapting this technique.- Biotechnological Approach for Tree Improvement in Red Sanders

Red Sanders (Pterocarpus santalinus Linn.) is an endemic species to Cuddapah geological formation. The heartwood of the tree is costliest and is being exported to Japan. Andhra Pradesh Forest Department has launched tree improvement programme to improve the quality of Red Sanders populations by multiplying desired superior phenotypes. The problems faced in standardising the techniques and the importance of Biotechnological approach for realising the objectives of the programme have been discussed. The advantages and procedures adopted in tissue culture and ischolar_maining the cuttings of Red Sanders are described. The scope for utilising the techniques for the tree improvement of Red Sanders for multiplication and production of F1 hybrids is discussed.- Vegetative Propagation of Red Sanders (Pterocarpus santalinus Linn.)

Ptrocarpus sanlalinus an endemic species to the region of Cuddapah geological formation is highly valued due to its export potential to Japan. The choice of the Japanese is for its sound wavy grained logs. The forest department of Andhra Pradesh tried for propagation of the species vegetatively by means of ischolar_mained cuttings, air layering and grafting. The present paper analyses the grafting, air layering and ischolar_maining experiment conducted in the past. The results indicate that the technique of grafting has limited scope in large scale propagation of the species. Similarly air layering has got its own limitations and requires further standardisation. Rooting of cuttings offers great scope in propogating the elite trees on a large scale vegetatively. For propagation of the species by adopting tissue culture technology has great potential and efforts are also on way to utilise this technique for establishing clonal seed orchards in Andhra Pradesh.- Rooting of Terminal Cuttings in Tamarindus indica Linn
