Seed germination studies in pterocarpus marsupium roxb, an important multipurpose tree

The seed germination study was conducted through both in vitro and in vivo methods in Pterocarpus marsupium a multipurpose medicinal tree with low seed germination and poor viability. Mature seeds were surface sterilized and were either cultured on MS medium [half and full strength] augmented with different concentrations of GA[3] or subjected to various treatments viz. DW soaking, hot water soaking, cone. H[2]SO[4], cone. HCI and acid-alcohol [1:1]. The study suggested that in vitro method was more efficient and quick in terms of percent germination [80%] and half strength MS medium supplemented with GA[3] at 0.25 mg 1[-1] proved to be the optimal dose for induction of maximum germination
