Foliar application is one of the fast and effective methods for providing of plants nutrition requirement, especially in the critical stages of growth. In this study, the effects of Nano chelated form of both iron (Fe) and manganese(Mn) each at three levels (0, 0.5 and 1%) were investigated on some qualitative traits of chr('39')Bidaneh Sefidchr('39') grapevine at two stages of unripe and ripe berries. Based on results, the amount of pH, titratable acidity (TA), total soluble solids (TSS), ascorbic acid and anthocyanin in unripe berries were affected significantly by different dose of Fe spray. Moreover, the different level of Mn was affected significantly unripe berries pH, TA, TSS and ascorbic acid content however; Mn not significantly affected unripe berries anthocyanin compared to control vines. The lowest berries pH content (2.5) was related to control vines at unripe stage and the highest of berries pH content (3.75) observed in 1%Fe-treated vines at ripe stage. Moreover, the lowest berries TA content (0.9 %) was related to 1%Fe-treated vines at ripe stage and the highest of berries TA content (1.75) observed in control vines at unripe stage. The lowest berries TSS content (9 0Brix) was related to control vines at unripe stage and the highest berries TSS content (25.4 0Brix) observed in1% Mn-treated vines at ripe stage. Also the results showed that the lowest berries anthocyanin content (0.02 mg/100g) was related to control vines at unripe stage and the highest berries anthocyanin content (0.071 mg/100g) observed in 0.5% Mn-treated vines at ripe stage. The maximum amount of berries ascorbic acid (24.6 mg/100g) was related to 1% Mn-treated vines at ripe stage and the minimum amount of berries ascorbic acid (9.04 mg/100g) observed in control vines at unripe stage. Totally, based on results, foliar spray of Fe and Mn Nano chelated led in improvement in qualitative traits of grape berries two during unripe and ripe stages.
