Abstract
Recently, a pomegranate physiological disorder called 'aril browning' or 'aril paleness' in which a part or all of the arils show discoloration, affect the quality of fruit and such fruits are not suitable for consumption. The present research design to evaluate the effects of jasmonates, salicilates and potassium nutrient on reducing this disorders and improving fruit quality. Ten treatments including salicylic acid (0.3, 0.6 and 0.9 mM), methyl jasmonate (0.5, 1 and 2 mM) potassium sulfate (0.5, 1 and 1.5%) and distilled water (control), were sprayed on pomegranate tree 10 and 45 days after full bloom and after harvest. Different parameters related to quality of fruit were measured. The obtained results indicated that salicylic acid could improve the total acidity, TSS, chroma and hue angel of skin and b* index of arils. Although the phenolic content of arils increased in all treatment compare to control, the differences were not significant. The highest antioxidant activity was observed in the 1.5% potassium sulfate treatment and the differences with the control were significant.
