| 520 | 3 | _aTwo cucumber (Cucumis sativus)cultivars, Seraset F1 and Rabina F1, and two pepper (Capsicum annuum)cultivars, California Wonder and Charliston 52, were grown hydroponically for six weeks to investigate the effectiveness of supplementary potassium (K)and phosphorus (P)applied to the root zone of plants grown at high (60 mM)NaCl concentration. Treatments used in this experiment were (i)control: nutrient solution alone, (ii)high salt: nutrient solution plus 60mM NaCl, and (iii)high salt with supplementary P and K: nutrient solution plus 60mM NaCl, 1mM KH2PO4, and 2mM K2SO4. Supplementary 1mM KH2PO4 and 2mM K2SO4 was added to nutrient solution for four weeks. Plants grown at high salt produced less dry matter and chlorophyll than those in normal nutrient solution for both cucumber and pepper cultivars. Reductions in both dry matter and chlorophyll concentrations were greater for pepper than cucumber. Supplementary K and P restored dry matter and chlorophyll concentrations for both species to levels similar to the control. Membrane permeability increased with high salt application and these increases were greater for pepper. Supplementary K and P restored membrane permeability in both species to levels similar to the control. Plant daily water use was decreased by high salt but it was restored with supplementary K and P to levels similar to the control. Sodium (Na)concentration in plant tissues increased for both species in the high salt treatment. Concentrations of P and K were in the de®cient range in the plants grown at high salt and supplementary K and P application corrected these de®ciencies | |
