The results showed that the calcium treatment during production improved the comprehensive quality of Huangguan pear fruit, delayed and reduced the occurrence of browning of fruit core, and enhanced its storage effect in the cold storage. Therefore, the calcium treatment improved the quality of stored pear fruit.展开更多

The results showed that calcium（ Ca） spraying during young fruit period increased Ca and VCcontents in the fruit,improved SOD and POD activities,and declined K content,K/Ca and the occurrence of fruit cracking. When spraying calcium inhibitor during young fruit period,it aggravated fruit cracking.展开更多
