Allelopathic effect of leaf extract of Morus alba L. on germination and seeding growth of some pulses

摘要

Laboratory study was conducted to see the allelopathic effect of leaf leachate concentrations of Morus alba L. on germination and seedling growth of Peas (Pisum sativum). Lentil (Lens esculenta) and Broad beans (Vicia faba), Data recorded at the conclusion of the study exhibited both stimulatory as well as antagonistic effects on all the recorded parameters i.e. germination, root length, number of secondary roots, shoot length and vigour index. In peas and broad beans up to 50 percent concentrationof leaf leachate there was a stimulatory effect on all the recorded parameters while beyond 50 percent leaf leachate concentration there is an antagonistic effect on the recorded parameters except for germination in broad beans. In lentil leaf leachateconcentration up to 25 percent stimulated the germination and seedling growth but beyond 25 percent antagonistic effects were recorded for all the parameters,
