摘要
研究了苦丁茶叶片水抽提液、根系分泌液对茶树等６种受体植物的种子萌发及其幼苗生长的影响，结果表明，苦丁茶叶片水抽提液、根系分泌物均含有化感物质，并在一定浓度范围内能抑制参试受体种子的萌发及其幼苗的生长；土壤能积累苦丁茶的化感物质，当累积到一定浓度时对茶树及其它植物发生化感抑制作用。
The allelopathic effects of aqueous extract of leaf and root exudates of Ilex macrophylla Bl. on the germination and seedling growth of 6 accepter plants,i.e. tea plant, radish, rice, cucumber, manybean, cabbage were studied. The study indicated that there are allelochemicals existed in aqueous extract of leaf and root exudates. Allelochemicals accumuted in soil can inhabite the growth of nearby plants if the concentration is high enough.
