| 摘 要： | 试验结果表明,苜蓿不同部位提取液对苜蓿种子萌发表现出不同的自毒作用。苜蓿地上部分浸提液对种子萌发的抑制作用大于根部各部分的提取液对其种子萌发的抑制作用,这可能是由于苜蓿的自毒物质地上部分的含量大于地下部分。此外,苜蓿的自毒作用呈现出明显的浓度效应。

| Abstract: | The results indicated that the different aqueous extracts from the alfalfa had different autotoxicity on its seed germination.The aqueous extracts' inhibition from the above ground parts of alfalfa is much stronger than its roots'.This is maybe that autotoxicitic compounds are concentrated in its leaves and stem.What's more,alfalfa's autotoxicity is relevant to the concentration of aqueous extracts. |
