بررسي اثر تركيبات آلوپاتيك جو خودرو (Hordeum spontaneum) بر ميزان پروتيينها، كربوهيدراتها و فعاليت برخي از آنزيمهاي گندم (Triticum aestivum L.)

A study on allelopathic compounds derived from Hordeum spontaneum on carbohydrates, proteins and some enzymes of wheat (Triticum aestivum L.)

Growth and physiology of plants influence by allelochemicals realeased from weeds by various methods. In this investigation, the effects of Hordeum spontaneum 10% w/v aqueous extracts on carbohydrates and proteins content and some oxidative enzymes activity of two wheat cultivars (Tajan and Shirodi) were studied. In the presence of allelopathic derived from Hordeum spontaneum, total proteins reduced in Tajan but increased in Shirodi cv. Polysaccharid content increased in Shirodi leaves by Hordeum spontaneum allelochemicala while the highest amount of reduced sugar observed in Tajan roots. We observed an decrease in ascorbate peroxidase, peroxidase and catalase activities, however polyphenoloxidase activity were increased. Protease activity decreased in the leaves while it increased in roots. The electrophoretic patterns of enzymes were differ with compared to control. Thus allellochemicals effect on different enzymes by various methods.
