1.
Based on the tests of the embryo viability,germination rates of whole seeds and the isolated embryos,the causes of seed dormancy of 6 species in genus of Pinus were studied by testing the biological function of the abstracts from the testa,endothelium and endosperm,and by the contents of endogenous hormones of the seed coats and endosperms of these different species.
