Abstract

Ectomycorrhizal fungi are commonly occurring in most of the conifers and a few angiosperms. In the present investigation, three different ectomycorrhizal fungi viz., Pisolithus tinctorius, Scleroderma sp. and Thelephora ramarioides were recorded in association with Acacia spp. And Eucalyptus spp. Plantations in low fertile soils of Andhra Pradesh. The frequency distribution of these fungi in association with different tree species was recorded. Root samples were processed for identification of these fungal associations. Significance of these findings is discussed.

Abstract

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.
