紫茎泽兰不同部位水浸液对萝卜种子萌发及幼苗生长的影响OA
Effect of Crofton Weed Aqueous Extract with Different Parts on Seed Germination and Seedling Growth of Radish
[目的]探讨恶性杂草紫茎泽兰的化感效应.[方法]以萝卜种子为受体,初步研究了紫茎泽兰不同部位(根、茎、叶)、不同浓度(0、10、20、30、40和50g/L)的水浸液的化感作用.[结果]与对照相比,紫茎泽兰根和茎水浸液对萝卜种子的发芽率及幼苗生长(根长和苗长)均呈现出“低浓度促进高浓度抑制”的趋势；而紫茎泽兰叶水浸液对萝卜种子的发芽率及幼苗生长则表现出“随着水浸液浓度的增加,三者均受抑制”的趋势,并且其受抑制程度随着水浸液浓度的增加而增强；在同一…查看全部>>
[Objective] The aim was to discuss the allelopathic effect of noxious weed crofton weed. [Method] The allelopathic effect of crofton weed with different parts (root, stem and leaf) aqueous extracts at different concentrations (0, 10, 20, 30, 40 and 50 g/L) was studied using radish seeds as the accepted bodies. [ Result] Comparing with the control, the effects of root and stem aqueous extracts of crofton weed on germination rate, seedling growth (root length …查看全部>>
