| 摘 要： | 以5种杂草水提液、醇提液对紫花苜蓿Medicago sativa种子萌发及幼苗生长的影响进行了研究。结果显示：瘦风轮Calamintha graclis、卷耳Cerastium sp.、看麦娘Alopecurus aequalis和黄鹌菜Youngia japonica对紫花苜蓿均表现出不同程度的化感作用。瘦风轮显著降低了紫花苜蓿的种子萌发率；看麦娘则显著降低了紫花苜蓿苗长；经卷耳和黄鹌菜处理的紫花苜蓿种子萌发率和苗长均显著低于对照。瘦风轮和卷耳主要以水提液影响紫花苜蓿的种子萌发和幼苗生长；黄鹌菜和看麦娘对紫花苜蓿的化感物质则主要是醇溶性的。FGC 901品种受杂草的化感作用的影响大于GT 13R+FD8品种。

| Abstract: | The allelopathy between weeds and alfalfa were studied andthe results showed that Calamintha graclis,Cerastium sp.,Alopecurus aequalis and Youngia japonica showed allelopathy to alfalfa.The seed germination of alfalfa treated with soak solution of C.graclis was significantly lower than that of the control;A.aequalis had a significant negative impact on seedling length of alfalfa;both the seed germination and seedling length of alfalfa treated with the soak solution of C.sp.and Y.japonica were lower than tho... |
