TOLERANCE TO SALINITY IN CULTIVATED PLANTS: AN AGRONOMIC VISION

Abstract

Stress, both biotic and abiotic, negatively affects the growth of plants. Particularly, salinity stress decreases the productivity of agricultural crops, and consequently the profitability of the affected production units. The excess of salinity causes ionic and osmotic stress and there have been considerable advances in the understanding of the biochemical, physiological and molecular processes that activate plants in the presence of salt. In this review, the response of plants to abiotic stress caused by salts and the importance of tolerance is analyzed from an agronomic perspective.
