Physiological response of vitis vinifera L. (cv. chenin blanc) grafted onto different rootstocks on a relatively saline soil

CITATION: Southey, J. M. & Jooste, J. H. 1992. Physiological response of vitis vinifera L. (cv. chenin blanc) grafted onto different rootstocks on a relatively saline soil. South African Journal of Enology & Viticulture, 13(1):10-22, doi:10.21548/13-1-2195.The original publication is available at http://www.journals.ac.za/index.php/sajevCertain physiological parameters, namely leaf water potential, stomatal resistance and rate of photosynthesis of Chenin blanc grafted onto 10 rootstock cultivars on a relatively saline soil under irrigation in a hot region (V), were measured for two growing seasons. Soil electrical resistance, which varied from 632 to 271 ohms in the shallower soil layers (
