Based on the valuable antioxidant activity of citrus fruits, in present study the effect of rootstock and the type of tissue on some fruit quality parameters including phenol, flavonoid, antioxidant and the content of hesperidin and naringin of orange and mandarin was studied. The experiment was conducted as a factorial design based on complete randomized blocks with four replications. Results showed that, the amount of titrable acid of thampson novel fruit was higher than that of page mandarin. Both fruits produced a higher titrable acid when citromelo was used as rootstock. The content of vitamin C of fruits of sour orange was higher than that of citromelo. Antioxidant activity and the content of total phenol, total flavonoid, and hesperidin of thampson novel fruits were significantly high. Contrary to the hesperidin, between thampson novel orange and page mandarin the content of naringin of page mandarin was at the highest level. Fruits on citromelo showed a higher antioxidant activity, flavonoid and hesperidin content. No difference on the amount of total phenol and naringin was observed between two different rootstocks. The accumulation of measured antioxidant compounds of peel is noticeable. Finely based on the obtained results it can be concluded that although the concentration of pharmaceutical and nutritional compounds strongly related to genetic, it seems that a higher quality and quantity of such compound could be achieved using a suitable rootstock.
