Abstract
Data of a formerly presented fertilization trial were re-arranged to make apples of different physiological status be characterised with nutritional relations.
Fruits of similar morbidity in senescence disorders were grouped in classes.
Due to local environmental conditions, a high calcium content is a regular property of fruits in this country.
Data suggest that increased sink power of apples may be correlated to storage potential, and the increased sink power changed the N/P ratio and K/Ca ratio in a reverse manner in leaves and fruits.
As the fruit lose in their physiological status, an increase of N/P ratios met with a decrease of K/Ca ratios in fruits, and vice versa, the fruit storage life was negatively correlated to decreased N/P ratios and increasing K/Ca ratios in leaves.
