苦瓜对8种蔬菜的化感作用

以8种海南主要栽培的蔬菜为受体,采用室内生测法研究苦瓜(Momordica charantiaL.)茎叶水浸提液对其化感作用。结果表明:苦瓜茎叶水浸提液对8种受体植物的种子萌发和幼苗生长均有一定的化感效应,且化感作用方式和强度在受体间及指标间存在显著差异;化感作用综合效应的平均值大小顺序为:辣椒黄瓜豇豆菜豆萝卜樱桃番茄胡萝卜番茄。试验结果为建立合理的栽培制度提供了理论和试验依据。

Allelopathic Effect of Momordica charantia on 8 Vegetables

With 8 kinds of common cultivation of vegetables in Hainan as receiver plants，indoor bioassay method was used to study the allelopathy of aqueous extracts of Momordica charantia leaves and stems．The results showed that the aqueous extracts of M. charantia leaves and stems to 8 kinds of receiver plants seed germination and seedling growth were the allelopathic effect of a certain，but the way and strength of allelopathy among species and indexes were significantly different．Integrated allelopathic effects of the average size were order to Capsicum annuum ＞ Cucumis sativus ＞ Vigna unguiculata ＞ Phaseolus vulgaris ＞ Raphanussativus ＞Lycopersicon esculentum var. cerasiforme ＞ Daucus carota ＞ Lycopersicon esculentum．The research results provided theoretical and experimental basis for the establishment of a reasonable cultivationsystem．
