Abstract:
An experiment was conducted during the year 2015-16 at Biotechnology-cum-Tissue Culture Centre, OUAT, Bhubaneswar, India to induce the rooting from the stem cutting of Saraca asoca Roxb. De Wilde under agro-shade net controlled condition. The selected healthy branches of Saraca asoca Roxb. De Wilde was cut into 15 cm length having 4 to 5 nodes (with in thickness 0.5-1.5 cm).The base positions of cuttings were dipped in the 100,300,500 and 800 ppm of IBA (Indole-3-butyric acid), NAA (α-Naphthalene-acetic-acid) and IAA (Indole-3-acetic acid) respectively for four hours along with a control (without treatment). After which the cuttings were planted in the polypots filled with rooting media consists of sand, soil and farm yard manure (FYM) in the ratio of 1:2:1. Maximum sprouting (80.00%), rooting (56.66%), Number of leaves (16.00), root number (4.66), root length (16.33 cm), fresh biomass (13.37 g), dry biomass (6.38 g) were observed in cutting treated with 800 ppm NAA. Hence for production of healthy seedlings, the stem cutting of 15 cm length should be treated with 800 ppm NAA for obtaining better quality seedling.
