| 摘 要： | 目的]研究外来入侵植物簕仔树叶片的化感作用,为揭示其潜在的生态危害提供参考。方法]配制不同浓度的簕仔树叶水提液处理3种茄科作物种子,按生物测定方法及公式计算其萌发速率指数、化感效应指数和综合指数。结果]随着簕仔树叶水提液浓度的增加,其对茄子、辣椒、番茄种子萌发的抑制作用增强,且抑制作用大小整体表现为茄子〉番茄〉辣椒;不同浓度簕仔树叶水提液对不同受体植物根生长的影响情况体现出复杂性。结论]簕仔树叶对3种茄科作物种子萌发均有较明显的化感作用。

| Abstract: | Objective] The aim was to reveal the potential ecological damage of M.bimucronata,the chemical sensitive effects of leaves water extracts were studied in this paper.Method]By using the biological determined methods and the formula,five different concentrations of leaves extracts were used to treat the three cultivated species in Solanaceae to calculate germination rate index,chemical sensitive effects index and composite index.Result]With the enhancement of the concentration,the negative effects increase... |
