摘要: 本实验选用核桃叶为供体材料,以不同科的莴苣、小麦、西红柿为受体材料,采用发芽和生长实验,研究了核桃叶提取物浓度对3种受体的化感作用。结果表明,不同浓度的核桃叶提取物对3种受体分别有抑制或促进作用。核桃叶提取物的化感活性成分主要是酚类及黄酮类化合物。这为核桃叶作为无公害植物源农药的开发利用提供了依据。

Abstract: The allelopathic effects of walnut(Juglans regia L.) leaf extracts on three plant acceptors:lettuce, wheat and tomato was explored by germination and growth experiments.Results showed that different concentrations of aquatic walnut leaf extracts had certain inhibitory and/or promoted effects on those acceptors, and major bioactive substances were found to be phenolics and flavonoids.This study can provide some basis for development of biorational pesticides.

Key words: allelopathy, Juglans regia L., leaf extracts, bioactive substances
