| Abstract | ||
| Two pot experiments ware carried out at the college of Agric and Forestry , Mosuel Univ ,in summer growing season of 2000 to determine the allelopathic effect of Sorghum halepenses on seed germination and growth of Sesamum indicum , Vigna sinensis , Solanum melongena , Cucumis melo Reticulatus .While second experiment had to investigate the allelopathic impact of Cyperus esculentus , Glycyrrhiza glabra , Helianthus annus Eucalyptus camaldulensis , Citrus rotundus on seed germination and rhizomes growth of S.Halepenses.Data was subjected to the convertional analysis of complet Randomized Design C.R.D. Results indicated that the plumule , radical and seedling dry weight of different species had inhibited when it treated with the aqueous extraction of S.Halepenses rhizomes if it compared with with leaves vegetative extraction . On the other hand , the leaves of Citrus rotundus , Eucalyptus camaldulensis and Helianthus annus Were significantly effect on seed germination of S.halepenses . Root extraction of Glycyrrhiza glabra had stimulated effect and increased the plumule length and dry weight of S.halepenses while Eucalyptus camaldulensis , Citrus rotundus leaves had inhibitor effect on growth of S.halepenses . | ||
