摘要

Uraria picta (Jacq.) DC. (Pithvan), Fabaceae, is an important medicinal woody herb used in an Ayurvedic preparation "Dashmula". The utilization of roots by uprooting the entire plants and the problems associated with the seed germination leads to shortage of root material for Ayurvedic preparation. The aim of the present study was to assess seed viability and the influence of presowing treatments on the seed germination and seedling development in U. picta. Application of 2,3,5-triphenyl tetrazoliumchloride test showed that 100% of embryos were viable. The treatments applied singly and in combination include acid scarification (H_2SO_4), cold, hot and boiling water, rubbing with sand paper, presoaking in gibberellic acid (GA_3) and application of cut to the seed coat followed by presoaking in distilled water. Significantly highest (100%) rate of seed germination and higher proportion of strong seedlings were observed in the seeds soaked in distilled water for 12 hr after application of cut to theseed coat. This was evident by the significantly higher emergence index, germination speed, germination value and vigor index when compared with the control and other treatments. The protocol developed for the seed germination and seedling development can be applied for raising a large number of plants of U. picta which will help in the conservation of plant and availability of root material for medicinal purposes.
