| 摘 要： | 以加拿大一枝黄花(Solidago canadensis L.)水浸提液处理3种蔬菜种子,加拿大一枝黄花地上部分浸提液(0.025～0.1 g/mL)能降低苏州青和生菜种子的萌发率,地上部分和地下部分浸提液均能显著抑制苏州青、萝卜和生菜种子的发芽势.经浸提液处理的3种蔬菜种子萌发的鲜根重和根长有所下降,地上部分浸提液对生菜和萝卜的芽长也起显著的抑制作用.结果表明:加拿大一枝黄花可能通过水溶性化感物质抑制蔬菜种子萌发和生长.

| Abstract: | The effect of water extracts from Solidago canadensis L on seed germination and growth of 3 vegetables were studied.Our results showed that the water extracts of S.canadensis inhibited seed of Chinese cabbage and lettuce.The water extract of above ground patr from S.canadensis decreased the germination potential of radish.The root weight and length of all tested seeds were decreased with the of the water extract.The bud length of lettuce and radish were inhibited by the water extract from the above parts of... |
