Measuring Soluble Ion Concentrations (Na+, K+, Cl−) in ...

2010-3-8 · Abstract. The control of Na + and Cl − uptake from soils, and the partitioning of these ions within plants, is an essential component of salinity tolerance. Genetic variation in the ability of roots to exclude Na + and Cl − from the transpiration stream flowing to the shoot has been associated with salinity tolerance in many species. The maintenance of a high uptake of K + is also ...
