Abstract: Keeping the importance of vegetative propagation in ensuring mass multiplication of seedlings particularly of those species, which are difficult to germinate through seeds, a systematic research trial was conducted to know the effect of PGRs on the effect of different PGRs on rooting and shooting behavior of Rauvolfia serpentina and Gymnema sylvestre stem cuttings. Research was laid out in Factorial Completely Randomized Design with 13 treatments replicated thrice. Parameters studied were rooting percentage, number of primary roots/cutting, length of the primary root, sprouting percentage and survival percentage of cuttings. Maximum rooting percentage (83.33 and 45.00%) was observed in Sarpagandha and Gudmar respectively under the treatment 750 ppm NAA and 750 ppm IBA. Maximum sprouting percentage of Sarpgandha was observed in 750 ppm NAA (86.67%), while in case of Gudmar, it was 61.67% in 750 ppm IBA. Maximum number of primary roots (3.20) in Sarpagandha cuttings was observed in 750 ppm IAA and in case of Gudmar; it was 3.43 in 750 ppm IAA. Maximum length of primary roots (4.69 cm) in Sarpagandha cuttings was observed in 750 ppm IAA and in case Gudmar, it was 10.31 cm in 750 ppm IBA. Maximum survival percentage (70.00%) in Sarpagandha cuttings was observed in 500 ppm NAA and in case of Gudmar, it was 45.00% in 750 ppm NAA. It could be concluded that to obtain uniform, healthy and vigorous seedlings of Rauvolfia serpentina, stem cuttings of length 15 cm, thickness 6-7 mm, having 4-5 bud should be dipped up to 5 cm in 750 ppm NAA for two minutes and transplanted in rooting medium. In case of Gymnema sylvestre, stem cuttings of length 15 cm, thickness 4-5 mm, having 4-5 bud should be dipped up to 5 cm in 750 ppm IBA for two minutes and transplanted in rooting medium.
