| 摘 要： | 用牛鞭草,胜红蓟和沟叶结缕草3种植物提取液处理鱼黄草和木豆品种3号、4号种子,测定种子发芽率、苗高、根长和苗鲜重。结果表明,牛鞭草提取液总体上对鱼黄草、木豆3号和4号产生了抑制种子发芽和幼苗生长的作用;胜红蓟提取液能明显抑制鱼黄草种子发芽和幼苗生长,显著降低木豆3号种子发芽率和苗高,高浓度胜红蓟提取液对木豆4号有抑制效应;沟叶结缕草提取液总体上对鱼黄草种子萌发和幼苗生长的抑制作用较小,对木豆3号稍有抑制效应,对木豆4号苗鲜重有显著抑制作用。

| Abstract: | Effects of extracting solution from Hemarthria altissima,Ageratum conyzoides and Zoysia matrella on seed germination and seedling growth of Cajanus cajan(cultivar No.3,No.4)and Merremia hederaceawere studied through germination tests.The results showed that the extracting solution from Hemarthria altissima dropped the seed germination rates of Cajanus cajan(cultivar No.3,No.4)and Merremia hederacea and inhibited seedlings growth in general.The extracting solution from Ageratum conyzoides significantly decreased the seed germination rate and seedling growth of Merremia hederacea and Cajanus cajan cultivar No.3,and its high concentrated solution showed inhibition effect to Cajanus cajan(cultivar No.4).The extracting solution from Zoysia matrella slightly showed the inhibition effect to Merremia hederacea and Cajanus cajan(cultivar No.3) in general,but it decreased the seedling fresh weight of Cajanus cajan(cultivar No.4) significantly. |
