角茴香根和地上部水浸液对杂草反枝苋的化感作用
Allelopathy of the Aqueous Extracts from the Root and Aerial Part of Hypecoum erectum L.on Amaranthus retroflexus L.
摘要
Abstract
The allelopathy of the aqueous extracts from the root and aerial part of Hypecoum erectum L. on seed germination and seedling growth of Amaranthus retro flexus L. were studied by adopting petridish bioassay. The primary results showed that the aqueous extracts from the root and aerial part of Hypecoum erectum L. with different concentrations inhibited the seed germination and root length of A. retroflexus L. , and the suppression increased with the increase of the concentration of aqueous extracts. Furthermore, there were dual effects on hypocotyl length of A. retroflexus L.: As the concentration of aqueous extracts from the root of H. erectum was lower than 0.030 g · mL-1 , the growth of hypocotyls was promoted, while higher than 0. 030 g · mL-1 could restrain the growth.关键词
