Response of Pongamia Pinnata Seedlings to Root and Shoot Manipulation Techniques

The aim of the present investigation was to evaluate the effect of ischolar_main trimming, shoot topping, pre-sowing seed soaking treatments and seed/ pod weight on seedling quality and early growth in Pongamia pinnata. Root coiling was reduced when ischolar_mains were trimmed at 5 cm length. Maximum number of nodules was observed in plants with trimmed ischolar_mains as compared to untrimmed. Shoot topping at 10 cm height resulted in maximum shoot and ischolar_main growth. In trial on effect of seed/pod weight on seed germination, maximum seed germination was achieved in seeds with minimum 100- seed weight among the different treatments tried. Among the pre-sowing seed treatments, maximum seed germination was observed with 8 hours of water soaking. Maximum height and diameter was observed in seeds with no water soaking treatments.
