A Study of seed germination and seedling growth of eggplant (Solanum melongena L.) affected by various solvents extract of leaves of Eucalyptus (Eucalyptus globulus Labill)
In order to investigate the allelopathic effects of leaf extracts of E. globulus on germination and seedling growth of eggplant cv. Mahali Jahrom an experiment was carried out using a completely randomized design arranged in a factorial scheme with 3 replicates. Treatments included 5 types of extracts including aqueous, methanolic, ethyl acetate, acetonic and benzene and different concentrations of extract at 5 level (0, 1.25, 2.5, 5 and 10 gram per liter). At the end of experiment germination and seedling growth characters including germination percentage, germination rate, shoot length, root length, fresh and dry weights of seedling were measured. Result indicated that the inhibitory effect was proportional to the concentrations of the extracts and higher concentration had the strongest inhibitory effect on germination and seedling growth. Results also revealed that in all cases ethyl acetate had most negative effect on germination and seedling growth of eggplant whereas aqueous extract followed by acetonic extract caused highest germination percentage, germination rate and seedling growth.
