Abstract

A biological phenomenon by which one plant releases some chemicals in the environment that affect the rate of germination, its seedling emergence and physiology and overall growth of neighboring plants is called allelopathy. The significance of study was checked allelopathic phytochemical potential of Daraikh (Melia Azedarach L.) leaves on Wheat. Leaves litter were used to examine the allelopathic effects of Daraikh (Melia Azedarach) at five concentrations (100, 200, 300, 400 g, control) parameters studied germination percentage (%), Speed of germination, plant height (cm), root length (cm), Shoot length (cm), coleoptile length (cm), Fresh weight (g) and dry weight (g), Tiller (plant-1) and chlorophyll content (ยต cm-2) of Triticum aestivum. All concentration of Leaves litter of Melia Azedarach showed pronounced inhibitory effect on all parameters of Triticum aestivum. Melia Azedarach exerted phytotoxic influence on Triticum aestivum at initial growth stages. Melia Azedarach exhibited a significant negative impact on germination of Triticum aestivum at 100, 200, 300, 400 g litter of leaves than control (Sterilized soil) repectively. Melia Azedarach halted the coleoptile length of Triticum aestivum @ 400 g leaves litter. Powdered leaves of Melia Azedarach in clay loam soil appeared to have strong allelopathic inhibition under maximum concentrations on growth and germination of Triticum aestivum. Hence, Melia Azedarach proved a strong allelopathic plant that should be planted aside from field to avoid harmful impacts during early growth stages of Triticum aestivum.
