- 摘要:
- 以衡水市景县一农田中的花生植株为试材，以蒸馏水为溶液浸提花生的根、茎、叶、花，配制成 10%、50%、100% 3 种浓度的浸提液，研究了花生浸提液对黄瓜种子化感作用的影响。结果表明：花生器官内有化感物质存在，且花生不同器官浸提液对黄瓜种子化感作用有不同程度的促进或抑制作用：100%茎浸提液对黄瓜种子发芽率促进作用最明显，100%叶浸提液对黄瓜种子发芽率抑制作用最明显；10%根浸提液对黄瓜幼苗根长促进作用最明显，10%叶浸提液对黄瓜幼苗根长抑制作用最明显；不同器官浸提液对黄瓜幼苗茎长和鲜重的影响效果接近。叶部浸提液均表现为抑制作用，根部和茎部均表现为促进作用，100%根部浸提液促进作用最明显。
- Abstract:
- Arachis hypogaea on the allelopathic effects of cucumber seeds were examined nearby Jing County of Hengshui，the different organs (root,stem,leaf,flower) by extraction of distilled water to progress activated material leaching,compounding three kinds of density (10%、50%、100%) of the original solution concentration.The results showed that it had allelopathic material in Arachis hypogaea，and Arachis hypogaea in different circumstances and different water extracts of different organs had different effect to promote or prohibit.100% stem extracts obviously promoted of cucumber seed germination rate，100% leaf extracts inhibited obviously on cucumber seed germination rate.10% the root extracts obviously promoted the cucumber seedlings root length and 10% the leaf extract inhibited cucumber seedling root growth obviously.The effect of different organ extracts had similar effect on cucumber seedling stem length and fresh weight.Leaf extracts showed inhibition effect.Root and stem extracts showed promoting role obviously，100% root extracts showed promoting role the most obviously.
