Abstract

Allelo-chemicals produced from leaves, roots, bark, fruits and seeds of many plants influence the growth and germination of another adjacent plant. A lab experiment was conducted to study the allelopathic effect of aqueous extracts of Eucalyptus leaves (Eucalyptus camaldulensis L.) on germination percentage and seedlings of three varieties of wheat. Experiment was laid out in steel trays with CRD factorial arrangement, having four replications in agronomic lab of University College of Agriculture and Environmental Sciences, The Islamia University of Bahawalpur, Pakistan during 2015. It has been observed from the experiment that aqueous extracts of Eucalyptus leaves at a concentration 10, 15, 20 and 25% had negative effect on wheat germination percentage and found significantly higher fresh and dry weight of Seedling in control treatment. With increasing the extract concentration of Eucalyptus the inhibitory effect also increased. The findings indicate that wheat sown in field under or near eucalyptus trees has inhibitory effect on germination, growth and ultimately resulting in lower yields of wheat.
