加拿大蓬种子生态适应性及其化感作用
Study on Ecological Adaptability and Allelopathy of Conyza canadensis Cronq Seeds
摘要
Abstract
Conyza canadensis is one of the most dangerous invasive plants in China. The relationship between biological invasion of Conyza canadensis and its seeds germination was discussed, seven items of Conyza canadensis were researched including temperature, illumination time, strength of illumination, suitable water, suitable matrix, seed viability and allelopathy of Conyza canadensis seeds water extract. The results showed that: the best germination conditions of Conyza canadensis seeds are 20 X., entire illumination, illumination for 12 h, 10% water content, and sandy matrix. Allelopathy of Conyza canadensis was shown on germination of tested plants seeds and growth of seedlings, indicating the wide ecological adaptability of Conyza canadensis seeds and its allelopathy promoting biological invasion of Conyza canadensis.关键词
