ALLELOPATHIC EFFECT OF Eucalyptus camaldulensis L. ON SEED GERMINATION AND SEEDLING GROWTH OF mungbean Vigna radiata (L.) Wilczek.

Abstract

The present study entitled “Allelopathic effect of leaves extract of Eucalyptus camaldulensis L. on the seed germination and seedling growth of mungbean Vigna radiata (L.) Wilczek” was carried in the Phytoecology Lab., Department of Botany, University of Peshawar, Pakistan.  The leaves extract was made of 5g, 10g and 15g of powder which were soaked in 100ml distilled water from 24, 48 and 96 hrs. The germination % was found more in the control and 5g/100ml extract as compared to  10g/100 ml and 15g/100 ml concentrations. As the concentrations were increased, the inhibitory effects of the leaves extract on seed germination were found to be increased. The length of radical and plumule were also measured more in the control followed by 5g (24 hrs) treatment and low at 15g (96hrs) treatment. These findings suggest that Vigna radiata and other closely related crops should not be planted close to the Eucalyptus camaldulensis L. which causes inhibitory effects on the seed germination and growth of neighbouring species. It is suggested that the allelopathy of Eucalyptus camaldulensis may be exploited in management of weeds in different crops after ascertaining the required tolerance and susceptibility of crops and weeds.
