| 摘 要： | 通过核桃枝叶水溶物对种子萌发和幼苗插条生长的研究结果表明,核桃枝叶水溶物对绿豆种子的萌发具有抑制作用,且核桃叶的化感作用强于核桃枝条的化感作用,处理间对种子萌发的影响是随着浓度的增大抑制作用增强。不同浓度核桃枝的水溶物对黄瓜幼苗插条增高和最长根长度的化感抑制作用随浓度增大而增强,对发根量的化感抑制作用则相反。

| Abstract: | By study of water extracts from walnut leaf and stem on the seedling quickset growth and seed germination,the results showed that water extracts from walnut leaf and stem have inhibited effects on seed germination of Phaseolus aureus.And allelopathy of walnut leaf is bigger than stem's.The higher the concentration of aqueous extracts on seed germination,the larger the inhibition is.With the concentration of aqueous extracts from walnut stem increasing,the inhibited allelopathy get strong on the heightening and the longest root length of cucumber seedling quickset,while the concentration increasing,the inhibited effects get weak. |
