Abstract: Plents of tubers were induced when stem apex grown up from the tuber of Pinallia ternata was used as explants to culture.The tubers 5mm in diameter were sieved to make artifical seeds.In natural conditions,the conversion rate of artificial seed is 98.4% after 30 days of cultivating.The output of artificial seed seedling is 2.02 times of cultivating seedling's,1.33 times of tube seedling's;the contents of alkaloid is 1.62 times of cultivating seedling's,1.12 times of tube seedling's,1.17 times of tuber wild ...
