Abstract
Abstract The effect of salinity on potassium (K), calcium (Ca), magnesium (Mg), phosphorus (P), and nitrate–nitrogen (NO3–N) concentration and partitioning was studied in a hydroponic culture of own-rooted grapevine, cultivar Thompson seedless (Vitis vinifera L.), or grafted onto the rootstocks 110R, 140Ru, 1103P, SO4, and 41B. Plants were grown in 25 L pots and exposed to salinity by irrigation for a period of 60 days with 50% Hoagland No. 2 nutrient solution also containing 5, 25, 50, or 100 mM NaCl. At the end of the stress period, concentrations of K, Ca, Mg, P, and NO3–N were measured in leaf blades, leaf petioles, shoots, trunk, and roots. Leaf blade, leaf petiole, and shoot P concentrations increased with salinity, whereas that of NO3–N and K decreased in all parts of the vine. Salinity had no effect on shoot Ca and Mg, trunk P and Mg, and root P, Ca, and Mg concentrations. Rootstock genotype significantly influenced the nutrient concentrations of different vine organs, except those of blade and root Ca, petiole Mg and NO3–N, shoot P and NO3–N, and trunk P and NO3–N.
