Abstract:

The allelopathic influence of aqueous extracts of Eucalyptus camaldulensis L. on germination (%) and seedling growth (fresh and dry weight) of wheat have been determined. It was noted that aqueous extracts at a concentration of 10, 15 and 20% had inhibitory effect on wheat seed germination and effect was found significantly higher than untreated control treatment. Fresh and dry weight of seedling was also reduced significantly over control. The inhibitory effects were increased as the extract concentration increased. These findings indicate that wheat sown in fields which had leaf litter of Eucalyptus camaldulensis L. will be adversely affected regarding germination, growth and ultimately yield of wheat.
