ntroduction
Crops grown in the arid and semi-arid regions are often
exposed to adverse environmental factors such as high soil
salinity. The reduction in the plant growth in the saline
environments may be due to either water relations or the toxic
effects of Na+ and Cl ions on the metabolism. Na+ influx
into the root cells elevates the cytoplasm Na+ concentration
and causes toxicity symptoms.
