Allelopathic Effects of Eucalyptus Globulus Labill. on Seed Germination and Seedling Growth of Eggplant (Solanum Melongena L.) [pdf]Paper  abstract   bibtex   
Eucalyptus spp. are known to contain various substances that are allelopathic. The objective of this study was to determine allelopathic effects of various solvent extracts (aqueous, methanolic, ethyl acetate, acetonic and benzene) of Eucalyptus globulus leaves in five concentrations ( , , , and g/L) on seed germination and early seedling growth of eggplant cv. Black Beauty. The experiment was carried out using a completely randomized design arranged in factorial scheme with three repl icates. The results showed that all extracts had inhibitory effects on germination and seedling growth although degree of their inhibitions was different. Methanolic extract had the highest inhibitory effect on germination percentage and rate, root and sho ot lengths and fresh and dry weights of eggplant seedlings whereas aqueous extract followed by acetonic extract had the lowest inhibitory effects. In all extracts, the reduction in germination and growth of eggplant seedlings increased significantly with i ncreasing concentration. The results suggest that leaf extracts of E. globulus had potent allelopathic activity although the activity differed depending on extract and concentration.
