Abstract:
Objective: To study the effect of volatile from isolated garlic sprouts on the germination characteristics of Angelica sinensis seeds under simulated continuous cropping stress. Methods: Treating the obstacle of A. sinensis seeds under simulate continuous cropping stress with the extract from Angelica Sinensis Radix and using isolated garlic sprouts to simulate garlic volatile allelopathy environment, so as to study the germination characteristics of A. sinensis seeds. Results: The extracts from Angelica Sinensis Radix inhibited the germination of A. sinensis seeds, and the higher the concentration was, the stronger the inhibition effects will be. The volatile from the isolated garlic sprouts promoted the germination of A. sinensis seeds, which was not treated with the extracts from Angelica Sinensis Radix at low concentration (50 g isolated garlic sprouts) and inhibited the germination at high concentration (100-200 g isolated garlic sprouts). The isolated garlic sprouts volatile had certain promoting allelopathy on the germination properties of A. sinensis seeds which were treated with the extracts from Angelica Sinensis Radix. When the fresh weight of the donor garlic sprouts was 50-100 g, the promoting effects on A. sinensis seeds germination reached extremely significant level (P<0.01). When the fresh weight of garlic sprouts was 200 g, the promoting effects were not significant (P<0.05). Conclusion: The volatile from the isolated garlic sprouts could alleviate the germination inhibition by extracts from Angelica Sinensis Radix.
