Potentiality of Colchicine in Induction of Polyploids in Jasminum sambac (L.) Aiton cv. Ramanathapuram Gundumalli

The study was commenced in a compulsion toaccomplish successful approach developing commercially viable polyploidy variety Jasminum sambac. Rooted cuttings of J. sambac cv. Ramanathapuram Gundumalli were treated with different concentrations colchicine (0.05%, 0.10%, 0.15%, 0.20% and 0.25%) for 48 hours. survival sprouting rates the treatments determined after 45 days treatment phenotypic stomatal characteristics plants recorded. Colchicine registered reduction plant height (76.00 cm to 27.33 cm), internodal length (3.88 2.64 cm) number flowering cymes per (56.33 20.44) comparison control. In untreated plants, polyploidy-induced developed leaves larger stomata lower frequency.
