Investigating the effect of Gall on Biochemistry compounds Quercus persica trees(Case Study: Blouran area, Lorestan Province)

Gall is a type of plant tissue deformation induced by some insects that often use it as feeding or as a shelter. One of the most important hosts of Gall inducing factors is Persian Quercus persica tree. In this research, the effect of Gall inducing factors on Biochemical compounds were studied with investigating the amount of antioxidant activity, condensed tannin, total tannin, total protein, flavonoid compounds, total phenol, non-soluble sugar and soluble sugar in a leaf that were randomly sampled from healthy twigs and with Gall of oak trees in Iran in Blouran area, Khorramabad city. The results showed that the amount of total phenol, total tannins, condensed tannin, insoluble and soluble sugar in twigs with Gall had significant increase than twigs with no Gall. Also, there was no significant difference in flavonoids compound, antioxidants and protein even though in twigs with Gall it more than twigs without Gall. The results indicate the effectiveness of secondary compounds change of oak leaves due to Galls.
