摘要: 以莴苣为试材,通过辣椒植株水浸液、水浸液醇溶组分和根系分泌3种方法收集化感物质,研究了不同浓度的化感物质对莴苣的化感效应。结果表明,3种方法收集的化感物质对莴苣均表现为高控低促的化感浓度效应,并且对根部生长的影响远大于地上部,不同生长时期的莴苣对化感物质的敏感度不同,苗期比发芽期敏感。

Abstract: Allelopathy of different concentrations hot pepper allelochemicals on lettuce was researched through lettuce seed germination and seedling growth.The results showed that lettuce seed germination and seedling growth were affected by hot pepper aqueous extracts,methanol soluble fractions in aqueous extracts and its root exudates.When the concentration was low,lettuce seed germination and seedling growth were promoted,but when the concentration was high,they were inhibited.The effect on root growth was greater than that of the top.Allelopathic susceptivity was various at different growth stages of lettuce,and it was more susceptive at seedling stage than at germination stage.

Key words: Hot pepper, Allelopathy, Allelochemicals, Lettuce
