تأثیر آللوپاتیک گیاهان پوششی بر روی جوانه زنی و رشد بذر گندم

According to the reports that there is the potential allelopathic effects of cover crops and sugar beet seed extract, Laboratory experiments were conducted in 2014 at the Agriculture Faculty of Agriculture, University of Mohaghegh Ardabili in a completely randomized design with three replications on seed germination and growth of wheat. To illustrate the effect of allelopathic of cover crops aqueous extracts including rey (Secale cereal), hairy vetch (Vicia villosa), sugar beet (Beta vulgaris) and rye and vetch mixture and distilled water (as a control) and osmotic solution of each cover crops were examined on seed Wheat of Zagros (037) cultivar with a total of 27 treatments. The results showed that the greatest effect of allelopathic of aqueous extracts on seed germination of wheat were, for sugar beet, rye, rye / vetch and vetch respectively. It also indicated that the aqueous extracts of the plants tested any greater deterrent effect than the osmotic effect of sucrose solution on the germination of wheat.
