Salinity tolerance of sugar beet (Beta vulgaris L.) cultivars in terms of growth, proline and soluble sugars concentrations, and Na+/K+ and Na+/Ca2+ ratios were analyzed in this study. Three-week-old seedlings of three sugar beet cultivars, ‘Gantang7’, ‘SD13829’, and ‘ST21916’, differing in salinity tolerance, were treated with 0, 50, 100, and 200 mM NaCl.(More)
Sugar beet (Beta vulgaris L.) is a natrophilic species well adapted to salinity and water stress. To investigate the physiological impact of salt on osmotic stress response, in the present study, 3-week-old seedlings were treated with a series of additional external NaCl concentrations (5–150 mM). Seedlings were also subjected to 0 or 240 mM sorbitol in the(More)
Salinity is one of the major abiotic stresses that limit the growth and productivity of sugar beet (Beta vulgaris L.). To improve sugar beet's salinity tolerance, the ZxNHX and ZxVP1-1 genes encoding tonoplast Na(+)/H(+) antiporter and H(+)-PPase from xerophyte Zygophyllum xanthoxylum were co-expressed by Agrobacterium tumefaciens-mediated transformation.(More)
