Impacts of Exogenous Calcium and Calcium Inhibitor on Fruit Cracking of Apricot

摘要

Calcium nitrate and EGTA( calcium inhibitor) were sprayed on Dafeng Apricot during young fruit period. 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.
