Plant Growth and Development under Salinity Stress
Plant growth and development are adversely affected by salinity – a major environmental stress that limits agricultural production. This chapter provides an overview of the physiological mechanisms by which growth and development of crop plants are affected by salinity. The initial phase of growth reduction is due to an osmotic effect, is similar to the initial response to water stress and show...
متن کاملSalinity Affects the Timing of Phasic Development in Spring Wheat
Understanding effects of environmental factors on crop phenological development is useful for predicting crop growth stages and scheduling management practices. We evaluated the effect of salinity on the rate of leaf appearance and the duration of critical stages of growth in wheat (Triticum aestivum L.) in terms of both thermal unit (TU; “C day) and phyllochron intervals. Two hard red spring w...
متن کاملSalinity Effects on Photosynthesis and Growth in Alternanthera philoxeroides (Mart.) Griseb.
Alternanthera philoxeroides, alligator weed, was grown at five different NaCl concentrations to determine the effect of salinity on factors related to the net rate of CO(2) uptake (P(n)). Over the range of 0 to 400 millimolar NaCl, P(n) declined 51%. Stomatal conductance declined in parallel with P(n) and as a result there was no reduction in intercellular CO(2) concentration and therefore no r...
متن کاملSalinity and light effects on growth, photosynthesis, and respiration of Grateloupia filicina
Effects of salinity and irradiance on growth, photosynthesis, and respiration of the commerŽ . cially important red alga Grateloupia filicina Lamouroux C. Agardh were examined in laboratory cultures. G. filicina thalli showed various degrees of growth over a broad range of experimental conditions, with a maximum growth rate of 13% d observed at 20‰ and 100 mmol photons m s. Salinity also altere...
متن کاملEffects of Cadmium and Salinity on Growth and Photosynthesis Parameters of Brassica Species
Hydroponic experiment was conducted to investigate the sole and combined effects of cadmium and salinity on growth and photosynthesis of Brassica napus (cultivar Abasin) and Brassica juncea (cultivar NIFA-Raya). Cadmium (as CdCl2; 3 and 6 μmol L) and NaCl (100 and 200 mM) were added either alone or in combination in Hoagland solution along with non-treated controls. Cd and NaCl treatments impos...
