Abstract

Tree fruit nursery production is becoming a highly specialized horticultural sector applying a high level of technology, automation and even modeling. Providing adequate water supply to rootstocks and young plantlets is an essential requisite but often, to avoid the risk of dryness, nurseries apply excess irrigation rates, with both physiological, quality and ecological costs. The present study uses experimental data to model the fluctuation in sap flow from apple rootstocks in two different climatic areas, a rather continental climate in eastern Albania and a Mediterranean one in western coast of Albania. The study was conducted on two commercial nurseries. Sap flow sensors based on the stem heat balance (SHB) method were installed on mounded daughter rootstocks of Pajam 2 apple rootstocks. Soil water potential was measured at two different depths. A portable meteorological station measured meteorological variables enabling the calculation of VPD (vapour pressure deficit) and ET (evapotranspiration).
