Sodium sulfate exposure slows growth of native pecan seedlings Phyton

Pecan [Carya illinoensis (Wanngenh) K. Koch] is one of the most important nut crops in arid and semiarid regions of Mexico. Here, most pecans are grown in saline soils having poor permeability which are further degraded by the use of low-quality irrigation water. Salinity adversely affects both pecan nut quality and yield. Little work has been done to explore the physiological effects of salinity on native pecan trees. Here we examine physiological changes determined by exposure of pecan seedlings to sodium sulfate (Na2SO4) at four concentrations: 1000, 2000, 3000 and 4000 mg/L applied twice weekly over a 70 d period. Control plants were similarly irrigated but with water free of Na2SO4. The aim was to identify and quantify the putative salinity damage to...
