艾蒿对大豆种子萌发和根系生长的化感作用研究
Study on Allelopathic Effect of Artemisia on Seed Germination and Root Growth of Soybean
摘要
Abstract
Five soybean varieties of Hefeng,Liaoxian,Huning,Maodou 29-2 and Korea-45 were treated with different concentrations (0,12.5,25.0,50.0 g·L-1) of Artemisia water extract.Germination rate,germination potential,germination index,root length,root hair width and root hair density were studied.The allelopathic effect of Artemisia on seed germination and root growth of different varieties were studied.The results showed that the general trend of the effect of the extract of Artemisia on the allelopathic effect of soybean was with the higher concentration of the extract,the stronger the inhibitory effect on the germination and root differentiation of soybean seeds,and the allelopathic effect of Artemisia on soybean growth was related with the variety,the sensitivity of different varieties of soybean to the allelopathy of Artemisia was different.The least sensitive of the five varieties was Hefeng,while the soybean 29-2 and Korea-45 were more sensitive.In addition,the sensitivity of soybean germination and root growth indexes to Artemisia was also different.The germination potential and root width were sensitive to Artemisia,which could be used as a measure of the allelopathy of Artemisia.关键词
