Air-layering on Dhakijam (Syzygium grande Wt. Wald.) and Garjan (Dipterocarpus turbinatus Gaertn. F.) was done in sapling and adult trees with coconut fibre warp and polythene warp. Adult trees responded better than saplings in respect ofrooting. Higher percentage of rooting was observed with coconut fibre warp than with polythene warp. The maximum success achieved in adult trees of Dhakijam and Garjan was 96 per cent and 56 per cent respectively. Rooted air-layered ramets were collected and planted in 30×45 cm poly.hene bags in the nursery for further establishment.
