Study on Allelopathic Effects of Arachis hypogaea Extracts on Cucumber Seeds

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.
