摘要: 采用留树保鲜和不留树保鲜的方式,研究采前喷施氨基酸钙对红美人杂柑果蒂周边果皮龟裂、褐变,果实落果,果实品质,及贮藏期间果实病害发生的影响。结果发现,采前喷施氨基酸钙,在留树保鲜和不留树保鲜的过程中均可以显著(p<0.05)减少龟裂数。贮藏40 d时,对于留树保鲜与不留树保鲜的处理,采前喷施氨基酸钙均可显著降低果蒂周边果皮组织中苯丙氨酸解氨酶和多聚半乳糖醛酸酶的活性。不留树保鲜下,喷施氨基酸钙显著降低了果实贮藏75 d时褐色蒂腐病、青绿霉病、酸腐病、炭疽病的发病率。留树保鲜下,喷施氨基酸钙显著降低了后期果实的落果率。在留树保鲜和不留树保鲜的过程中,喷施氨基酸钙显著提高了贮藏10 d时果实中的可溶性固形物、总糖、可滴定酸含量。总的来看,喷施氨基酸钙有助于减少果皮龟裂,降低病害发生率,提高果实品质。

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 40th 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 75th 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 10th day during the on-trees and regular storage. In general, spraying amino acid calcium could reduce peel cracking, disease incidence and improve fuit quality.
