| 摘 要： | 针对白三叶Trifolium repens与黑麦草Lotium perenne、弯叶画眉草Eragrostis curvula混播时导致后2种植物数量减少甚至消失的现象,通过白三叶的根部、地上部和植株水提液对黑麦草和弯叶画眉草种子进行发芽实验,以及白三叶与黑麦草、白三叶与弯叶画眉草种子混播进行实验,研究表明:白三叶(幼苗、2年生植株根及茎叶)的水提取液在原液以及稀释20倍时对受体植物的胚根和胚芽的生长均产生明显的抑制作用,而在100倍稀释液时表现出一定的促进作用;白三叶与黑麦草及白三叶与弯叶画眉草种子混播实验,表明5∶1的比例为最佳混播比例.

| Abstract: | A study on allelopathy in Trifolium repens was conducted by the bioassays of mixed sowing and seedlings co-culture of T.repens and Lolium perenne,T.repens and Eragrostis curvula Seed germination of L.perenne and E.curvula was assessed by the extracts from roots,aerial parts and the fresh plant of T.repens.The results were depicted as the following: The extracts of all part in T.repens inhibited the plant growth of L.perenne and E.curvula at the rate of raw and 20fold solutions.In addition,the 100-fold extract prompted both receptors growth.The above results suggested that T.repens would influence the growth of L.perenne and E.curvula because of its allelopathic potential,.The most perfect ratio of seeds mixed sowing T.repens and L.perenne,T.repens and E.curvula was found as 5:1 shown in the mixed sowing test. |
