Effects of Water Extracts of Codonopsis pilosula on Medicines Seeds and Their Seedlings
摘要
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.关键词
