Natural leachates ofEucalyptus globulus (throughfall, stemflow, and soil percolates) were collected daily during rainy spells in the vegetative period (February-July), and their effects on the germination and radicle growth ofLactuca sativa were measured. Concurrently, the effects ofL. sativa of topsoil and leachates from decaying litter were determined. The results suggest that toxic allelochemicals released byEucalyptus globulus may influence the composition and structure of the understory of the plantation and that this effect is attributable mainly to the decomposition products of decaying litter rather than to aerial leachates. The soil may neutralize or dilute allelopathic agents, at least below the top few cms.
在营养生长期（2 月至 7 月）的雨季，每天采集按树（桉树属）的天然沥出物（穿透雨、茎流和土壤渗出液），并测量其对莴苣种子萌发和胚根生长的影响。同时，还测定了表土和枯枝落叶分解物沥出液对莴苣的影响。结果表明，按树释放的有毒化感物质可能会影响人工林的林下植被的组成和结构，而这种影响主要归因于枯枝落叶的分解产物，而不是空中沥出物。土壤可能会中和或稀释化感物质，至少在几厘米深的表层以下是这样。
