Inhibitory Effect of Wild Onion (Asphodelus Tenuifolius Cav.) on the Seedling Growth of Zea Mays L.

Abstract

Allelopathy is a mechanism in which allelo-chemicals produced by plants may inhibit or enhance the associated plant growth. In the present investigation it is observed that the higher concentration of shoot and seed extracts of Asphodelus tenuifolius Cav. have shown the inhibitory effect on germination of the tested crop, Zea mays L. Further, different concentrations of shoot and seed extracts of A. tenuifolius Cav. have shown significant inhibitory effect on germination of seedlings and growth attributes of Zea mays L. Plants, which were not treated with any extracts (control) showed maximum germination and growth pattern. Whereas at lower concentrations of shoot and seed extracts of A. tenuifolius Cav., significant growth was observed in shoot and root length of Zea mays L.
