Growth and development of potatoes under salinity and water deficit

Abstract

The agronomic and physiological responses of potato to salinity and to water deficits were determined. The experiment consisted of five treatments: three salinity levels and two restricted amounts of water. Plant height, leaf area and fresh weight accumulation were significantly affected by the salinity and moisture treatments. Stem number, leaf elongation and the content of dry-matter in leaves, stems and tubers were hardly affected. Harvest index, an important agronomic trait, was markedly improved by the different treatments.
