| 摘 要： | 研究了太子参茎叶和连作土壤水浸液对其种子萌发和种苗生长的影响。结果表明:高浓度茎叶浸提液抑制太子参种子萌发;低浓度的茎叶浸提液对太子参种苗生长有促进作用,高浓度的茎叶浸提液抑制了太子参胚根和胚芽的生长;连作土壤浸提液对太子参胚根的生长有极显著的促进作用;化感作用可能是导致太子参连作障碍的重要原因。

| Abstract: | Effect of aqueous extracts from shoot and continuous cropping rhizosphere soil of Pseudostellaria heterophylla on its seed germination and seedling growth were studied.The results indicated that seed germination of P.heterophylla was inhibited by its shoot extract with the highest concentration.Higher concentrations of shoot extract inhibited,and lower concentrations of shoot extract improved growth of both embryo and radicle of P.heterophylla.Aqueous extract of continuous cropping soil significantly improved radicle growth of P.heterophylla.Allelopathy was presumedly an important reason that causes continuous cropping obstacle of P.heterophylla. |
