DIURAPHIS NOXIA به شته روسي TRITICUM AESTIVUML ارزيابي تغييرات چند عامل بيوشيميايي در مقاومت هفت ژنوتيپ گندم

Evaluation of some biochemical factors for resistance of seven bread wheat(Triticum aestivum L.) genotypes to Russian aphid (Diuraphis noxia)

In order to evaluate the variation in wheat leaf total free phenol, total free amino acids, free proline and total protein in reaction to Russian aphid, an experiment was carried out on 7 bread wheat genotypes(witli different levels of resistance). The experiment was performed in greenhouse conditions at Shiraz 1999 The results indicated that Russian aphid caused stress on all genotypes and total free phenol increased in all of them. High level of resistance in genotypes was correlated with free proline content before contamination (r=0.87,p
