芫荽不同部位浸提液对水稻种子化感效应比较研究

Comparative study of allelopathy effects of aqueous extract from different parts of coriander on rice seeds

以芫荽为供体材料、水稻为受体材料,探讨芫荽不同部位不同浓度浸提液对水稻种子的化感作用,结果表明:不同浓度芫荽器官(根、茎、叶)浸提液对水稻种子萌发有较强的抑制作用,随处理浓度升高,抑制作用增强;在相同浓度下,不同芫荽器官的浸提液对水稻种子萌发和生长的化感作用强度依次为茎>叶>根。

The allelopathy effects of aqueous extract from different parts of coriander on rice seeds were examined. The resuhs showed that different concentration solvent extracts from coriander root, stem, leaf had strong inhibition on rice seed germination, and inhibition would become stronger along with the treatment concentration was increased. Under the same concentration, the order of restraining effect from strong to weak was stem, leaf, and root.
