Features of the Assimilation Surface of Sweet Cherry Trees of Different Ripening Terms

Abstract

The article presents the results of a study of the assimilation surface of sweet cherry trees of different pomological cultivars. The aim of the research was to study the morphological and varietal characteristics of the deciduous cover of sweet cherry trees, depending on the timing of fruit ripening. As a result of observations and analysis, the morphological features of the leaf apparatus of trees, leaf area and total leaf surface were determined as one of the main indicators of the photosynthetic potential of fruit trees. It was established that a characteristic feature of the varieties Turquoise, Drogana yellow and Donetsk coal was an increase in the area of the leaf blade with the age of the trees. Sweet cherry cultivars of late ripening were characterized by a smaller area of the leaf blade compared to cultivars of early and medium maturity. The size of the leaf blade did not depend on the strength of the growth of the fruit tree.
