Abstract
In recent years, colorless pomegranate arils changed to critical damage in the pomegranate orchards of Iran.
This issue has concerned growers and exporters of this economic commodity.
Thus, several researchers studied the physiological disorder of pomegranate white arils (PWA). Regardless of other factors affecting PWA, this study was conducted to evaluate the effect of foliar application of Fe and Zn fertilizer on the reduction of PWA. The factorial experiment was carried out in a completely randomized block design with 3 replications where each replication comprised 4 trees.
The first factor, cultivar in two levels (Khazar and Shisheh-Cap) and the second, fertilizer treatments in 12 levels (ferrous sulfate at three levels of 0, 0.5, and 1%, Zn sulfate at three levels of 0, 0.5 and 1%, liquid Fe chelate (Fe-EDDHA 0.6) at three levels of 0, 0.5 and 1%, ferrous sulfate, and Zn sulfate combination at three levels of control, each with equal concentrations 0.5% in one compound and 1% in another combination.
The results showed that the amount of PWA in Khazar was lower than Shishe-Cap (17.29%) and foliar application of Fe and Zn fertilizer decreased significantly white arils in both Khazar and Shisheh-Cap. The least white arils were observed via foliar application of Zn sulfate 1% in Khazar and Fe sulfate 1% in Shisheh-Cap decreased amounts of PWA 88.34 and 82.94%, respectively, compared to the control.
Based on the results of the presented study, foliar application of Zn sulfate 0.5 and 1% in Khazar and Fe sulfate 1% in Shisheh-Cap as superior treatments were recommended to improve the physiological disorder of pomegranate white arils.
