Fig. 3

The combination effect of mineral oil, potassium sulfate, and calcium sulfate on berry ascorbic acid content of Sultana grapevine. The means with common letters in each column according to Duncan's test are not significantly different (P < 0.05). V0 = 0.00% mineral oil, V1 = 1.00% mineral oil; K0 = 0.00% K2SO4, K1 = 3.00% K2SO4; C0 = 0.00% CaSO4, C1 = 2.00% CaSO4
