Abstract :

Present study was carried out to study the allelopathic effect of aerial and underground parts of Eucalyptus alba L. on germination and early growth seedling of Berseem (Trifolium alexandrinum L.) in vitro and in vivo conditions. Different plant parts viz., leaf, bark, flower, root extracts were used to run the experiment under laboratory and pots respectively. Maximum germination was observed in all the extracts of plant parts over control whereas, maximum shoot length and root lengths were observed at 25% concentration of leaf and flower extract and 100% concentration of bark and root extract of Eucalyptus respectively. In case of in vivo conditions maximum germination, shoot length and root length was observed in 25%, 50% concentrations respectively in all the extracts as compared to control. Germination and early seedling growth of four extracts were reduced significantly. The relative responses of different extracts were Foliar>Root> Flower> Bark subsequently.
