摘要/Abstract

摘要： 为明确不同质量浓度党参（Codonopsis pilosula）秸秆水浸提液对蒙古黄芪（Astragalus membranaceus）、黄芩（Scutellaria baicalensis）和柴胡（Bupleurum chinense DC）3种中药种子萌发及幼苗生长的影响，设置0、0.025、0.050、0.100、0.200 g/mL 5个党参秸秆水浸提液质量浓度，研究其对上述3种中药种子萌发及幼苗生长的化感作用。结果表明，党参秸秆水浸提液明显降低了3种中药种子的发芽率与发芽指数，且水浸提液质量浓度越高抑制作用越大。党参秸秆水浸提液对3种中药幼苗生长的化感作用存在差异，不同质量浓度均对蒙古黄芪幼苗苗高表现为促进作用，对其根长、幼苗鲜质量和干质量均表现为低质量浓度促进、高质量浓度抑制；党参秸秆水浸提液高质量浓度抑制黄芩幼苗苗高，但不同质量浓度对黄芩幼苗根长、鲜质量和干质量均表现为促进作用；党参秸秆水浸提液不同质量浓度对柴胡幼苗生长均表现为较强的抑制作用。党参秸秆水浸提液对3种中药种子萌发均具有化感抑制作用，对蒙古黄芪和黄芩幼苗生长指标的化感效应存在差异。党参秸秆水浸提液对3种中药的综合化感效应指数的影响也存在差异，对黄芩的综合化感效应指数值均大于0，表现为促进作用；0.025 g/mL党参秸秆水浸提液处理对蒙古黄芪的综合化感效应指数大于0，表现为促进作用，其余质量浓度下其综合化感效应指数均小于0，表现为抑制作用；对柴胡的综合化感效应指数值均小于0，表现为抑制作用。与蒙古黄芪和黄芩相比，党参秸秆水浸提液对柴胡抑制作用较强。

Abstract: To clarify the effects of different concentrations of Codonopsis pilosula straw water extract on the seed germination and seedling growth of three traditional Chinese medicines,Astragalus membranaceus,Scutellaria baicalensis,and Bupleurum chinense DC,five concentrations of Codonopsis pilosula straw water extract were set at 0,0.025，0.050，0.100，and 0.200 g/mL to study their allelopathic effects on the seed germination and seedling growth of the three traditional Chinese medicines.The results showed that the water extract of C.pilosula straw significantly reduced the seed germination rate and germination index of three traditional Chinese medicines,and the higher the concentration of the water extract,the greater the inhibitory effect.There were differences in the allelopathic effects of the water extract of C.pilosula straw on the seedling growth of three traditional Chinese medicines. Different concentrations had a promoting effect on the height of A.membranaceus seedlings,while low concentrations promoted and high concentrations inhibited the root length，fresh and dry weight of seedlings;The high concentration extract of C.pilosula straw soaked in water inhibited the height of S.baicalensis seedlings,but different concentrations had a promoting effect on the root length，fresh and dry weight of S.baicalensis seedlings;The water extract of C.pilosula straw with different concentrations showed strong inhibitory effects on the growth of B.chinense DC seedlings.The water extract of C.pilosula straw had allelopathic inhibitory effects on the seed germination of three traditional Chinese medicines,but there were differences in allelopathic effects on growth indicators of A.membranaceus and S.baicalensis seedlings.The influence of water extract of C.pilosula straw on the comprehensive allelopathic effect index of three traditional Chinese medicines also varied.The comprehensive allelopathic effect index on S.baicalensis was greater than 0,indicating a promoting effect.The comprehensive allelopathic effect index of 0.025 g/mL C.pilosula straw water extract treatment on A.membranaceus was greater than 0,indicating a promoting effect.At other concentrations，the comprehensive allelopathic effect index was less than 0,indicating an inhibitory effect.The comprehensive allelopathic effect index on B.chinense DC was less than 0,indicating an inhibitory effect. Compared with A.membranaceus and S.baicalensis，the aqueous extract of C.pilosula straw has a stronger inhibitory effect on B. chinense DC.
