Abstract

Abstract:

In the present study, the effects of preharvest spraying amino acid calcium on peel cracking, peel browning, fruit drop, fruit quality and the occurrence of fruit diseases of citrus hybrid Hongmeiren were explored during the on-trees and regular (off-trees) storage. The results showed that spraying amino acid calcium could significantly (p<0.05) reduce the number of cracks during the on-trees and regular storage. During the on-trees and regular storage, spraying amino acid calcium significantly decreased the activities of phenylalanine ammonia-lyase and polygalacturonase on the 40^th day. For the regular storage, spraying amino acid calcium significantly decreased the incidence of phomopsis stem-end rot, citrus green mold, citrus sour rot and citrus anthracnose on the 75^th day. For on-trees storage, spraying amino acid calcium significantly decreased the fruit-dropping rate in the later stage. Besides, spraying amino acid calcium significantly increased the content of soluble solids, total sugar and titratable acid on the 10^th day during the on-trees and regular storage. In general, spraying amino acid calcium could reduce peel cracking, disease incidence and improve fuit quality.

Key words: amino acid calcium, citrus hybrid, peel cracking, fruit quality
