Description 249-250
In vivo shoot induction in hypocotyls and rooting of the regenerated shoots of Bruguiera gymnorrhiza (Linn.) Sav., was standardised as a new method of vegetative propagation. Rooting response of the air-layers made from multiple shoots with the aid of exogenously applied plant growth regulators (IAA+IBA) by pre-girdling is studied. Multiple shoots were induced in 80 % of the hypocotyls treated and the number of regenerated shoots varied from 2-5 with an average value of 3.5 per hypocotyl. Better rooting performance (80 %) was recorded in air-layers treated with IAA+IBA (3000 mg l-1 each). More than 80 % of the rooted air-layers survived in the nursery in polybags. Thus, through this method, 2-3 times more planting materials could be made available for vegetative propagation of B. gymnorrhiza.
