Abstract:
The rhizosphere soil and different parts of Polygonatum sibiricum Red.were used as experimental materials,and three common crops (radish,wheat,Chinese cabbage) were used as the receptor crops.The indoor bioassay method was used to compare the water extract and alcohol extract of different parts of Polygonatum sibiricum Red.and the rhizosphere soil.The effects of water and alcohol extracts on seed germination rate and root length of three receptor crops were compared,and allelopathic effect index and comprehensive effect index were calculated,to preliminary understand the existence of allelochemicals in Polygonatum sibiricum Red.and provide data support.The results showed that the allelopathic effect of extracts from rhizosphere of Polygonatum sibiricum Red.on the seed germination and seedling growth of three kinds of receptor crops was extremely weak,while there were certain allelochemicals in different parts of Polygonatum sibiricum Red.,and the contained allelochemicals were mainly water-soluble components.The comprehensive allelopathy effects of different parts of Polygonatum sibiricum Red.on the three kinds of receptor plants were as follows:fruit>rhizome>leaf>stem.The extracts of rhizome and fruit of Polygonatum sibiricum Red.had extremely significant inhibitory effect on the seed germination and seedling growth of three kinds of receptor crops.
