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.
