Abstract

The micropropagation of neem (Azadirachta indica) was accomplished by culture of buds from crown branches of a mature tree, basal-sprouts of another mature tree and a single juvenile plant. Cultures derived from these three different sources showed significant variation in in vitro response. In case of the crown and basal-sprout explants, addition of 12.5 µM PVP-40 in the establishment medium controlled leaching of phenol growth inhibitors. Phenolic leaching was not observed in juvenile explants. DKW medium (with 0.22 µM BA) was significantly better than MS for shoot proliferation. Shoot cultures of crown branch origin did not elongate and eventually died after the third subculture. In the presence of 4.9 µM IBA in half-strength DKW, 90% of the shoots and 100% of basal-sprout and seedling explant origin, formed roots. Plantlets from both explant types showed 90% survival after acclimatization.
