Abstract

Taxus wallichiana Zucc. (Himalayan yew), is precious for taxol or paclitaxel removal used in the research of anti-cancer drugs (ovarian cancers, AIDS related cancers and other indications). It is a slow growing tree species due to its poor natural regeneration and very low seed germination. The present investigation tested the consequence of different plant growth regulators such as , Indole Butyric Acid (1BA), Indole-3- Acetic Acid (1AA) and Naphthalene Acetic Acid (NAA) on adventitious  rooting  of Himalayan yew shoot cuttings in four different seasons (spring, summer, autumn and winter) under nursery conditions. Shoot cuttings were treated with diverse concentrations of IBA, IAA and NAA. However, IBA at 1000 ppm in spring season (Mar-May) showed best response in stipulations of root length, root number and rooting percentage. The present investigation reveals that this method has the potentiality of using the young shoot cuttings of Himalayan yew in presence of plant growth regulating hormone IBA for its propagation and production on large extent to congregate the increasing stipulate
