Abstract:
Keeping the importance of vegetative propagation in ensuring mass multiplication of seedlings particularly of those species, which are difficult to germinate through seeds and to multiply the seedlings of uniform genetic composition, identical to parental type transmission, a systematic research trial was conducted to know the effect of PGRs on growth, rooting and survival of stem cuttings of Gudmar at AICRP (M&amp;APs) farm, BAU, Ranchi. Research was laid out in Factorial Completely Randomized Design with 13 treatments replicated thrice. Minimum number of days taken for initiation (3.00 days) of shoot emergence was observed in 7 PGRs treatments. Maximum number of days taken for completion of shoot emergence was 16.00 days in 250 ppm IAA. Maximum rooting percentage (45.00%) was observed in 750 ppm IBA, while maximum sprouting percentage was observed in 750 ppm IBA (61.67%). Maximum number of primary roots (3.43) cuttings was observed in 750 ppm IAA, while maximum number of secondary roots (76.40) cuttings was observed in 750 ppm IAA<em>. </em>Maximum length of primary roots (10.31 cm) cuttings was observed in 750 ppm IBA, while maximum length of secondary roots (2.23 cm) cuttings was observed in 750 ppm IBA<em>. </em>Maximum number of sprouts (2.35) was observed in 750 ppm IBA, while maximum length of shoots (3.05 cm) cuttings was observed in 750 ppm IBA<em>. </em>Maximum number of leaves (17.52) was observed in 750 ppm NAA and<em> </em>maximum basal diameter of shoots (1.97 mm) was observed in 1000 ppm IBA<em>. </em>Maximum area of leaves (4.82 cm<sup>2)</sup> was observed in 750 ppm IBA and<em> </em>maximum survival percentage (45.00%) was observed in 750 ppm NAA<em>. </em>Sprouting trend in <em>Gymnema sylvestre </em>cuttings indicates that maximum sprouting was occurred between 19-20 days. Average sprouting percentage under PGR treatment varied from 40-45%.
