Calcium regulates K+/Na+ homeostasis in rice (Oryza sativa L.) under saline conditions
To investigate the Cake Set effects of Ca2+ on cation accumulation and K+/Na+ selectivity, in this study, two-week-old rice (Oryza sativa L.) plants were exposed to 25 or 125 mmol/L NaCl with or without 10 mmol/L CaCl2.At low salinity (25 mmol/L NaCl), Ca2+ significantly decreased Na+ accumulation in roots, increased K+ accumulation in shoots, and
