Effects of salinity (NaCl) on the content photosynthetic pigments in barley varieties (Hordeum vulgare L.)
Keywords:
barley, salinity, chlorophyll, carotenoids, tolerance,Abstract
Barley varieties contrasting in their tolerance (according to preliminary results) to salinity (Asem, Sault, Odesskaya - 100) were taken to study the content of photosynthetic pigments in saline conditions. With increasing concentration of NaCl decreased concentration of chlorophyll a and b, and carotenoids. In tolerant varieties Asem and Saule content of photosynthetic pigments in saline conditions was higher than in non-resistant variety Odesskaya-100. Photosynthetic pigments content directly affects the rate of photosynthesis, which directly influence on crop yields. Contents of photosynthetic pigments are an integral indicator of plant resistance to adverse environmental conditions.References
