Abstract
Abstract Aubergine eggplant plants (Solanum melongena L.) were grown under greenhouse conditions with nitrogen and phosphorus fertilization individually, or both, and with a large amount of organic matter and CaSO4 in the soil superficie. The irrigation water was strongly brackish. In the plants, nitrate and phosphate showed an obvious mobility, whereas chloride and sulfate were relatively immobile. Cations in the form of potassium and ammonium were highly mobile, during the growth cycle, whereas the other cations tested were immobile. Translocation of anions was weak with little change in concentration throughout the growth cycle, whereas cations showed marked variations in different stages due to the influence of NH4 + and K+ mobilization. The accumulation of cations was offset by hydrogen extrusion to maintain foliar pH within physiological limits. Sharp changes in pH were buffered by the effect of citric acid as an organic anion, which absorbed the excess positive charge. Alterations in cations increa...
