Like many other medicinal plants , Taxus baccata is also facing extinction in its natural habitats due to increased market demand and consequent excessive destructive harvesting. Vegetative propagation through stem cuttings was tried for germplasm of Taxus baccata collected from Lokhandi area of Dehra Dun District (Uttaranchal) with varying concentrations of different phyto-hormones (IAA , IBA , NAA and GA3) and modes of application. IBA was the most suitabJe hormone , foUowed by IAA , NAA and GA3 respectiveJy for the induction of higher ischolar_maining percentage , number of ischolar_mains and length of ischolar_mains. The study revealed that IBA at 10 ,000 ppm is optimum for induction of better ischolar_maining percentage , higher number and greater length of primary ischolar_mains in the juvenile stem cuttings of Taxus baccata.

Abstract


Like many other medicinal plants , Taxus baccata is also facing extinction in its natural habitats due to increased market demand and consequent excessive destructive harvesting. Vegetative propagation through stem cuttings was tried for germplasm of Taxus baccata collected from Lokhandi area of Dehra Dun District (Uttaranchal) with varying concentrations of different phyto-hormones (IAA , IBA , NAA and GA3) and modes of application. IBA was the most suitabJe hormone , foUowed by IAA , NAA and GA3 respectiveJy for the induction of higher ischolar_maining percentage , number of ischolar_mains and length of ischolar_mains. The study revealed that IBA at 10 ,000 ppm is optimum for induction of better ischolar_maining percentage , higher number and greater length of primary ischolar_mains in the juvenile stem cuttings of Taxus baccata.
