Box 1 the economic cost of salinity the major economic cost of salinity is the reduced income to farmers caused by the reduced yield areas where salinity occurs are always arid or semiarid, and so crops are always limited by water, but they can also be limited by the salt concentration in the soil, especially when rainfall is below average. Salinity stress alters nutrient uptake and causes the damage of root and leaf anatomy in maize.
This review deals with the adaptive mechanisms that plants can implement to cope with the challenge of salt stress plants tolerant to nacl implement a series of adaptations to acclimate to salinity, including morphological, physiological and biochemical changes these changes include increases in the root/canopy ratio and in the chlorophyll. To cope with salt stress plants respond with physiological and biochemical changes that aim at the retention of water despite high external osmoticum and the maintenance of photosynthetic activity and these enable plants to become tolerant an understanding of the mechanisms by which salinity affects photosynthesis would aid the improvement. The main point is that excess salinity in soil water can decrease plant available water and cause plant stress there are several factors that hinder water flow from the soil to the roots one is the soil-root contact, and as the root dries out it shrinks away for the soil particles therefore, soils of higher salinities retain a greater amount of water, thus.
