Allelopathic Effect of Water Extract of shoot and leaves of Glycyrrhiza glabra and Eucalyptus camaldulensis on seed Germination of mung bean under laboratory condition
Tauheed ul Haq
Abstract
The current study was undertaken to evaluate the allelopathic potential of Glycyrrhiza glabra and Eucalyptus camaldulensis leaves and stem extract on the seeds germination, radical & plumule length, fresh & dry weight of V. radiata (L.) R. Wilczek. The experiments were conducted in petri dishes with three replicates in ecology lab department of botany University of Peshawar, Pakistan in 2022. Different concentration of plant extract (0 %, 25 %, 50 % and 100 %) were used in the study. Five ml leaves and stem extracts of both plants of different concentration were applied to each treatment except control. The result of the study shows that the both plant extract adversely affects all the tested parameters in mung bean. The allelopathic effect of tested plant are dose depended i.e the allelopathic effect of Glycyrrhiza glabra leaves and stem extract negatively affect all tested parameters, as the concentration of the extract increase the adverse also increase. Hence it could be concluded that the leaves and stem extract contain water soluble allelochemicals which adversely affect the tested plant. So it is suggested that mung bean plant should not be planted close to G. glabra and E, camaldulensis due to adverse effects on its growth.
