Abstract
The present study was designed to determine the allelopathy effects of aqueous extracts of leaves of two medicinal plants of Sapindus mukorossi Gaertn and Leucaena leucocephala (Lam.) de Wit. on seed germination, radicle length, mitotic index and chromosomal aberrations in two verities of vegetable crop pea (Pisum sativum), the most popular in India. The results of the present experiments revealed that the extracts of the two medial plants have an inhibitory effect on seed germination, radicle growth, mitotic index and chromosomal aberrations in crop pea owing an occurrence of allelochemicals.
