摘要(Abstract):

人参、西洋参忌连作,作者报道近年来国内外从化感作用角度研究人参和西洋参的连作障碍问题。综述了人参、西洋参化感作用的最新研究进展,从化感物质的收集提取到其对人参、西洋参种子萌发,幼苗生长和抗氧化酶活性及病原菌和愈伤组织的影响等方面综合分析了人参、西洋参中的化感作用,认为化感作用是人参、西洋参连作障碍的主要影响因子之一。并在此基础上指出人参、西洋参化感作用研究中存在的主要问题:研究成分是混合物,具体起作用的成分和物质尚不明确;以单个化感物质为研究而忽视了化感物质间的相互作用。今后应深入开展人参和西洋参特有的化感物质及化感物质间相互作用的研究,以及人参、西洋参化感物质与环境影响因子的互作关系,特别是化感物质在土壤中的迁移和转化等环境化学行为,化感物质与土壤微生物的相互关系及共同对人参和西洋参生长的影响。
Both ginseng and American ginseng can not be replanted on the same soil consecutively.The article reviews the development and progress of studies on the replant failure of ginseng and American ginseng with a special focus on allelopathy in recent years.The allelopathy effect in ginseng and American ginseng is reviewed from following aspects: collecting and extracting allelochemicals,effects of such allelochemicals on seeds germination,seedlings growth,antioxidant enzyme activities in ginseng roots,growth of ginseng pathogens and ginseng callus,and more.It is presumed that inhibitory allelopathy is one of the many possible factors contributing to the replant failure of ginseng and American ginseng.Based on that,the paper points out problems in current researches on the allelopathic effect of ginseng and American ginseng: the allelochemicals are consist of a mixture,which one plays the specific role is not clear;concentrating on a single allelochemical while ignoring the interaction among allelochemicals.It is suggested that further study for this area should be focused on the interactions among allelochemicals and interactions between allelochemicals and environmental impact factors.Another area of needed research is that of the migration and transformation of allelochemicals in soil and microbial involvement in allelopathy on the growth of ginseng and American ginseng.
