通过种子萌发和幼苗生长试验,探讨黄香草木犀水浸提液对其自身及4种常见杂草生长发育的影响.结果表明,黄香草木犀水浸提液对其自身和其他杂草都存在明显的化感作用,但其化感作用强度则取决于受体植物种类及浸提液的浓度.种子萌发试验表明,黄香草木犀水浸提液降低其自身和狗尾草的发芽率,而提高马齿苋和牛筋草的发芽率,且均在高浓度时效果显著(p＜0.05);但对反枝苋却有"低抑高促"作用.除了牛筋草在高浓度(3.3％～10.0％)时发芽势有所增加以外,黄香草木犀水浸提液明显降低其自身、狗尾草、反枝苋和马齿苋的发芽势,且随着浓度增加而抑制作用显著.幼苗生长试验表明,黄香草木犀水浸提液增加了 2种双子...

Through seed germination and seedling growth experiment,aqueous extraction of Melilotus officinalis was used to test the effects of allelopathy on seedling growth and development of its own and four other weeds.The results showed that there was clear allelopathic effect of Melilotus officinalis on itself and other weeds,but its efficacy depended on species and the concentration of extraction.According to the seed germination experiment,it showed that the aqueous extraction of Melilotus officinalis reduced the germination rate of itself and gree...
