| 摘 要： | 为了研究烟草凋萎叶早期腐解液及其不同组分的化感作用,以对化感物质具有高敏感性的莴苣(Lactuca sativa)为指示材料,对烟草品种K326凋萎叶早期腐解液及其分离后的各组分分别进行了化感潜力的生物测定.结果表明:1)早期腐解液及其组分随处理浓度的增大对莴苣种子萌发的抑制效应逐渐增强,且显著降低了种子萌发速率,并延...

| Abstract: | To study the allelopathic effects of inchoate decomposing liquid of tobacco withered leaves and its compositions,lettuce(Lactuca sativa) seeds,as a sensitive species to allelopathy,were exposed to the withered leaf decomposition of flue-cured tobacco K326 and its compositions.Results showed that the germination of lettuce seeds were inhibited by tobacco withered leaf decomposition and its compositions,and the allelopathic effects became stronger as the treatment concentration increased.The germination rates... |
