Abstract: Plants may be affected directly or indirectly by allelochemicals which may be released from plants or microorganisms. In this study, the allelopathic effect of leaf leachate of Eucalyptus camaldulensis Labill was examined on germination, growth, morphological and physiological criteria of sorghum (Sorghum bicolor) and kidney-bean (Phaseolus vulgaris). Leaf leachate was tried at 5, 10 and 20% concentrations and sterilized distilled water used as control. Seed germination, seedlings dry matter, shoot/root length were significantly reduced by all concentrations in both species (at 0/05 level). Decrease in chlorophyll content, soluble sugar content and consequently protein content is proportional to the increase in concentration of leaf leachate in both species.
