The effects of sodium chloride on the water status, growth, and physiology of sugar beet subjected to a range of soil water potentials were studied under controlled conditions. Sodium chloride increased plant dry weight and the area, thickness, and succulence of the leaves. It increased the water capacity of the plant, mainly the shoot, but there was no evidence that it altered the relationships between leaf relative water content and the leaf water, osmotic, and turgor potentials or changed the way stomatal conductance and photosynthesis responded to decreasing leaf water potential.
The greater leaf expansion in sodium-treated plants is thought to be the consequence of adjustments made by leaf cells to accommodate changes in ions and water in a way that minimizes change in water and turgor potentials. It is also suggested that the greater water capacity of treated plants buffers them against deleterious changes in leaf relative water content and water potential under conditions of moderate stress.
