Abstract
Dalbergia sissoo is an important commercial tree species known for its variety of adaptive and economic traits. Ontogeny plays a significant role in adventitious rooting in Dalbergia sissoo as mature trees of 12 yr of age do not exhibit marked rooting. However, cuttings from young donors receiving auxin treatment induce ample rooting for mass cloning and plantation programmes. Despite variable response to growth regulators in different experiments, IBA treatment with 4000ppm concentration clearly maintains superiority for rooting in juvenile and coppice shoot cuttings of Dalbergia sissoo.
