| 摘 要： | 采用生物检测方法，初步探讨了3个不同品种多花黑麦草（Lolium multifolorum）茎、叶水浸提液对紫花苜蓿(Medicago sativa)品种赛迪10的化感作用。结果表明，3个不同品种多花黑麦草化感作用大小不同,品种Barextra叶的水浸提液在3个质量分数处理下对受体紫花苜蓿有促进作用，而Barmega叶的水浸提液在质量分数10.0%和7.5%时却对紫花苜蓿有抑制作用；不同器官茎、叶水浸提液化感作用表现也不同，品种Jumbo和Barextra茎的水浸提液对紫花苜蓿的种子发芽有抑制作用，叶的水浸提液却有促进作用；不同质量分数浸提液化感作用表现不同，3个多花黑麦草品种在质量分数10.0%时对紫花苜蓿种子发芽、根长及苗鲜质量有抑制作用，而在质量分数5.0%时表现出促进作用。

| Abstract: | The biological detection techniques were used to determine the allelopathy effectiveness of leaf and stem extracts from three varieties of Lolium multifolorum on Sardi 10 of Alfalfa.The results of this study showed that the allelopathy effectiveness of three varieties of L.multifolorum on alfalfa were different.The extract from Barextra leaf encouraged Sardi 10 seeds to germinate.The 10.0% and 7.5% concentrations of extract of Barmega leaf inhibited Sardi10 seeds to germinate.This study also found that the ... |
