综述了萜类化合物的化感作用及其与植物群落演变的关系，重点讨论了萜类化合物的生物合成，常见类型与存在的主要植物种类进入环境的途径，水中的溶解性等等；同时论述了萜类化合物对植物种子，幼苗的抑制，促进作用及其自毒现象。

ECOLOGICAL CHARACTERISTIC OF TERPENOIDS AND THEIR ALLELOPATHIC EFFECTS TO PLANTS

Terpenoids which widely exists in the higher plants is one of the metabolite of plants, and it plays a important role in the ecological systems. The relationship between the allelopathic effects and the community succession was reviewed. In this paper some subjects such as the bio synthesis of terpenoids, main plant species containing terpenoids, major compounds of terpenoids, ways of the terpenoids entering into environment and their water solubility were discussed. It was also expounded that the terpenoids can cause inhibition, promotion and autotoxic action on seed germination and seedling growth. The factors affacting these effects were also discussed.
