Abstract

There is an increasing interest in breeding salt tolerant plants due to salinization and a growing food demand. Since the current methods of identifying salt tolerant plants take rather long and are expensive, there is an upcoming interest in a new method of identification: measuring K+ efflux. With a non-invasive ion flux measurement (MIFE) the K+efflux in roots is measured after introduction of salt (NaCl). Comparison of experiments which measured K+efflux in barley, wheat, grapevine rootstock and irises indicate that there is a relation between the capability of a plant to retain K+and salt tolerance. The higher the K+efflux, the lower the salt tolerance. To optimize measurements and compare outcomes, a universal method is proposed regarding measuring place, measuring time and NaCl concentration. Overall, K+efflux proves to be a solid indicator of salt tolerance and could therefore improve breeding programmes for salt tolerance.
