Compared the response of the plant Solanum tuberosum L. mid-varieties Nakra to chloride salinity which depending on lighting conditions. Regenerated plants were produced in vitro from apical meristem and grown on half-strength Murashige and Skoog medium using a hydroponic unit in controlled-climate conditions. At the age of six weeks, the plants were exposed to salt stress (125 mM NaCl, 7 days); at the same time, plants were grown on white light with red or blue light. Plant response to salt stress was estimated by growth and physiological parameters. Potato plant tolerance to chloride salinity rose after short-term exposure to blue light, which has been first shown in this study. The protective effect of blue light was based on its ability to stimulate the accumulation of low-molecular weight organic compounds with antioxidant activity. |
