|Authors:||Basak, U. C.|
|Abstract:||<i style="">In vivo </i>shoot induction in hypocotyls and rooting of the regenerated shoots of <i style="">Bruguiera gymnorrhiza </i>(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<sup>-1 </sup>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 <i style="">B. gymnorrhiza.</i>|
