Study of the water regime of some cherry varieties in the north-eastern conditions of Romania

Abstract

The soil and climate conditions in the North-East area of Romania are considered suitable for sweet cherry cultivation, but sometimes problems may arise due to the intensification of global climate changes, mainly in terms of the water component. This study was conducted during the year 2022 using three sweet cherry tree cultivars as biological material: 'Van’, 'Andreiaș’ and 'Margonia’ from Research Station for Fruit Growing (RSFG) Iași. The aim of this research was to evaluate physiological aspects of the water regime of the sweet cherry tree by determining the rate of dehydration, water content as well as the stomatal conductance of the leaves from different levels of the trees. Physiological determinations were carried out in three different phenological stages according to Biologische Bundesanstalt, Bundessortenamt and CHemical Industry (BBCH) scale: full flowering (BBCH 65), fruit growth (BBCH 75), and fruit ripening (BBCH 89) and were correlated with the registered climate data.
