The Effects of Edible Coatings on the Postharvest Quality of Citrus Fruits as Affected by Granulation

Table 1

Main causes of granulation in citrus.

CausesReference

Delay in harvesting and/or late maturity[4, 19, 20]
Vigorous and rapid tree growth[12, 21]
Quick ripening[21]
Adverse atmospheric condition: cold weather during the maturity period[5, 20]
Sink competition among the different plant parts, i.e., fruits, roots, and leaves.[9, 22, 23]
Rootstocks and cultivars type[3, 24]
Higher water potential in juice cells[25]
High temperatures during flowering and fruit set[12]
Calcium deficiency[20]
Enzymes activity: polyphenol oxidase (PPO), peroxidase (POD), superoxide dismutase (SOD), catalase (CAT), pectin-methylesterase (PME), and cellulose[26]
