Correlation Analysis between Cracking and Mineral Element Content of Apricot Fruit

[...]Ca deficiency is the main factor affecting fruit cracking in apricot. [...]apricot is one of the most widely distributed and cultivated trees in the north. The correlations between Zn and Mn contents and cracking index were weaker; and the correlations between Fe, K, Mg and Cu contents and cracking index were extremely weak. [...]Ca content is one of the main factors affecting the fruit cracking of apricot. [...]the cracking degree and its influencing factors differ greatly among different regions, different fruit tree species and different years, and different cultivars also have different absorption ability for exogenous Ca. [...]how to promote the absorption of Ca by fruit after application of exogenous Ca and to ensure that the Ca2+ in fruit is maintained at a high level is the issue that needs to be solved in the next step.
