Title: Inhibitory allelopathic effects of weed leaf leachates on germination and seedling growth of wheat (Triticum aestivum L.)
Abstract: A laboratory germination experiment was conducted to assess the effect of leaf leachates on 14 major weed species of study area, namely, Ageratum conyzoides L., Ammania baccifera L., Anagallis arvensis L., Caesulia axillaris Roxb., Chenopodium album L., Commelina benghalensis L., Cyperus difformis L., Cyperus rotundus L., Desmodium trifolium (L.) D. C., Lathyrus aphaca L., Ludwigia perennis L., Melilotus indica (All.) Fl. Pedem., Phyllanthus niruri L. and Rumex dentatus L. on germination and seedling growth of two varieties of Triticum aestivum L., namely, UP 2338 and HUW 234. The fresh leaves of mature weeds were cut into small pieces and were used to prepare leachates of 5, 10, 15 and 20% concentration. Treatment of wheat seeds with these leachates showed that nearly all the test weeds had inhibitory effect on per cent germination, shoot length and root length of both the test cultivars at different concentrations. The inhibitory response was found to be positively correlated with the leachate concentration. Statistically significant reduction in nearly all the test parameters of both the cultivars by leaf leachates of all the tested weeds was found to correspond to 15% treatment level.
