Effects of rootstock and irrigation regime on hydraulic architecture of Vitis vinifera L. Cv. Tempranillo

Abstract

Rootstock hydraulic properties are probably the keys to drought or waterlogging resistance. This work evaluates the effects of two rootstocks (110R, SO4) and two irrigation levels (ET0, 0,5 ·ET0) on the hydraulic architecture of Tempranillo. The experiment was carried out on potted plants near Barcelona (Spain). Hydraulic resistance in trunks was measured by low pressure method and using a High Pressure Flow Meter (HPFM). The trunks of Tempranillo grafted onto 110R showed a lower resistance than the ones grafted onto SO4. The grafting point showed a higher resistance than the cultivar segment and the rootstock segment. HPFM results were more consistent than low-pressure measurements.
