[Dormancy characteristic and inner inhibitory substances of fructus Schisandrae]

It has been found for the first time that there is quite a number inhibitory substances in the testa and kernel of dormant Fructus Schisandrae. Differences have alas been found between the inhibitor extracted from the testa and that from the kernel. The fromer is stronger in inhibiting the root elongatain of Brassica sp, whereas the latter is stonger in inhibiting the seeds germination. The result shows that the dormancy of Fructus Schisandrae the inhibitors contained in the testa and kernel.
