This study is aimed to investigate the effects of kaolin and gibberellic acid on sunburn and quality of pomegranate fruit cv 'Rabab Neiriz'. Kaolin was applied on branches and fruits at two concentrations, 2.5 and 5 percent, followed by two monthly replications. Gibberellin was applied as another treatment at 150 mg/l at same time of first application of kaolin. Results indicated that application of kaolin at 5 percent significantly increased fruit and aril size, and reduced fruit skin thickness. However, application of kaolin in both concentrations and gibberellic acid showed a significant increase in aril water content. Anthocyanin content of aril reduced in fruits treated by 5 percent of kaolin. Gibberellic acid prevents sunburn intensity and percentage in comparison to those of control. The lowest rate of sunburn intensity and percentage was observed in kaolin treated fruits and there was no significant differences between 2.5 and 5 percent of it. As a conclusion, Kaolin is an effective treatment for reducing sunburn and increasing fruit quality in pomegranate fruit.
