Lots of calli were. successfully induced by culturing the mature embryos of Taxus chinensis, Taxus chinensis var. mairei (Fujian) and Taxus chinensis var. mairei (Sichuan). The highest calli-inducing frequency was 95 7%,98.4% and 91.7% respectively. The cellular and morphological observation revealed that somatic embryos at different growth stages could be produced from the calli which were cultured for some time under appropriate culture condition. For the above three materials, the largest number of somatic embryos per 100 calli was 127, 91 and 33 respectively.
