Effect of Auxins on Macropropagation of Taxus baccata Linn. Through Stem Cuttings

Like many other medicinal plants, Taxus baccata also has come to the phase of extinction in its natural habitats due to increased market demand and consequent excessive destructive harvesting. Vegetative propagation through stem cuttings was tried for germplasm multiplication of T. baccata collected from Tangmarg range of Pripanjal division (Kashmir). Cuttings were treated with different auxins (IAA, IBA and NAA). IBA was found to be the most suitable hormone, followed by NAA and IAA respectively for the induction of higher callusing percentage, ischolar_maining percentage, number of ischolar_mains and ischolar_main length. The study revealed that IBA at 500 ppm is best for ischolar_maining of the stem cutting of Taxus baccata.
