Abstract
Aim. The effect of various concentrations of sodium chloride on growth parameters, the activity of antioxidant enzymes, the amount of photosynthetic pigments and total sugar beet proteins was studied.
Methods. The objects of study were varieties of sugar beets Tarifa, Taltos and Cooper. Plants were grown in a controlled greenhouse for 60 days at different salinity levels (0.2 and 0.5% NaCl and Na2SO4). The parameters of leaves and roots, the activity of catalase (CAT) and benzidyl-peroxidase (BPO), the content of photosynthetic pigments and total proteins during the growing season were determined.
Results. Although leaf and root parameters were stimulated or not affected at low salinity, a higher salt concentration significantly reduced all signs of growth. At a high salinity level, the Tarifa variety had a significantly higher leaf area and root with compared to other varieties. In the variety Tarifa, the activity of CAT was higher than in other varieties, but the activity of BPO, the content of total protein and photosynthetic pigments was higher in the varieties Taltos and Cooper. The salinity of the medium reduced physiological and biochemical parameters in different varieties of sugar beets to varying degrees, and these features of the varieties should be taken into account in breeding work.
