ABSTRACT. – Sap flow response of cherry trees to weather condition. The main goal of our study is to measure water-demand of cherry trees budded onto different rootstocks by sapflow equipment and to study the sap flow response to the meteorological factors. The investigations are carried out in Soroksár in Hungary at ‘Rita’ sweet cherry orchard. The pattern of sapflow was analyzed in relation of solar radiation, vapour pressure deficit and air temperature. Between solar radiation and sap flow was found a parabolic relation, daily pattern of sapflow is in close relation (cubic) also to vapour pressure deficit. No significant relationship existed between sapflow and air temperature. The sapflow performance of sweet cherry trees on different rootstocks showed typical daily characters.
