棉花植株水提取液对种子萌发和幼苗生长的自毒作用
Autotoxic Effect of Aqueous Extract from Cotton on Seed Germination and Growth
摘要
Abstract
[Objective] The water extracts of cotton plants were tested for inhibitory activity of seed germination and seedling growth. [Method] The seeds germination rate, germination vigor, and germination index were measured as seed germination parameters and stem thickness, cotyledonary node high, root and stem and leaf wet weight of seedling were measured as seedling growth parameters. [ Result] The water extract of cotton exhibited " low to promote high - suppression" on seed germination. The effect on the stem, root and leaf biomass synthesis had various degrees of obvious or remarkable significance. The seedling growth was exhibited on the overall performance of the inhibition. [ Conclusion ] High concentrations of water extract of cotton inhibited cotton seed germination and seedling growth. Auto toxicity plays a significant role in continuous cropping.关键词
