Abstract
Enhancement of initial growth of slow growing forest species has an advantage in terms of their survival and establishment in the main field. Rattans being the slow growing forest species survive better if early growth is enhanced. In order to accelerate the early growth and therefore to produce vigorous and sturdy seedlings, gibberellic acid, an endogenous growth hormone at a concentration of 200 and 300 ppm was applied exogenously to the seedlings of Rattans for 3 months at an interval of one week. Various growth parameters studied revealed that there is significant increase in clump height and dry weight in GA treated seedlings over the control. However, the culm number did not differ significantly across the treatments. The per cent increase in clump height and dry weight in GA treated seedlings was to the extent of 50 to 80% over the control seedlings. The results clearly indicate that there is possibility to boost up the initial growth in slow growing forest species like Rattans using a potent growth regulator Gibberellic acid.
