目的:研究黄连不同部位水浸液对黄连生长的自毒作用。方法:采用生物测定方法,研究不同浓度的黄连根系分泌物、根茎浸提液、植株残体分解产物、根际土浸提液对黄连种子萌发、幼苗及成株生长的影响。结果:黄连不同部位水浸液对黄连生长有较强的抑制作用。结论:自毒作用
Objective: To study the autotoxicity of aqueous extracts of Coptis chinensis to Coptis chinensis growth. Methods: The bioassay method was used to study the effects of different concentrations of rhizoma coptidis exudates, rhizome extracts, plant residue decomposition products and rhizosphere soil extracts on the seed germination, seedling growth and plant growth of Coptis chinensis. Results: Different parts of Coptis water extract of Coptis strongly inhibited growth. Conclusion: Autotoxic effect
