Abstract
The aim of this paper was to study continuous and discrete parameters of plant-water relations in mature apricot trees, in order to analyse the physiological basis of these plant-based sensors as well to determine the most sensitive indicator of plant water deficits. The experiment was performed during 1998-2001 in twelve-year-old apricot trees (Prunus armeniaca L., cv. Búlida), growing under field conditions in Murcia, Spain (semi-arid climate, with 1500 mm average annual evaporation and 350 mm rainfall) in a clay loam texture soil (128 mm m-1 available soil water content and 1.45 Mg m-3 bulk density). Trees were submitted to two drip irrigated treatments: a control treatment irrigated at 100 % of seasonal ETc and a water deficit treatment (WD) irrigated at 50 % of the control treatment. The diurnal courses of leaf water potentials, leaf conductance, net photosynthesis, leaf temperature, sap flow and trunk diameter fluctuations were studied throughout one growing season. The deficit ...
