This paper studies the asexual propagation and seed propagation characteristics of P.peduncularis(GrahamexBentham)Bentham in natural conditions.The result shows that: the seed coat of P.peduncularis(GrahamexBentham)Bentham is very thick and substantial,so it is not easy to propagate by nature.By means of experiment,it shows that : the seeds should be soaked by concentrated sulfuric acid with consistency of 98% for 120 minutes.At this time,the germination percentage is hightest at 70%,to deal with the seed coat by mechanical method,the rate of emergence reaches 94%.
