摘要
研究了外来植物南美蟛蜞菊(W ed elia trilobata(L.)A.S.H itche)茎叶水浸提液对绿豆(V igna rad iata L inn.)、萝卜(R aphaus sativusL inn.)、青菜(B rassica ch inensisL inn.)等经济作物的生化他感作用.结果表明,南美蟛蜞菊的茎叶水提液对几种供试植物种子的发芽指数、萌发率及幼苗的苗高和根长均有不同程度的抑制作用.
The allelopathy of the water extract from Wedelia trilobata(L. )A. S. Hitche stems and leaves was studied on several economic crops (Vigna radiata Linn. , Raphaus sativus Linn. , Brassica chinensis Linn. ). The results showed that the water extract from Wedelia trilobata stems and leaves had different inhibitory effects on the above test crops in the percentage of their seed germination, the indexes of their seed-sprouting speed, and the growth of the roots and shoots of the seedlings.
