Effects of aqueous extract of Eucalyptus globulus on germination and seedling growth of sorghum.

The application of leaf extracts of Eucalyptus globulus decreased the seed germination of sorghum with increase in the leaf extracts concentration. The extracts also inhibited the shoot and root length of sorghum seedlings with increase in Eucalyptus extracts concentration but the number of lateral roots was increased. The extracts also influence the biochemical parameters (protein content, sugar content, total phenol content and nitrate reductase activity).
