Study of some physiological characteristics of potato tissue under salinity stress
Journal Title: International Journal of Farming and Allied Sciences - Year 2018, Vol 7, Issue 1
Abstract
Potato is one of the most important crop plants and plant tissue culture is very important in the cultivation of plants. Salinity is one of the environmental factors that affects plant growth. In this research, some of the physiological characteristics of potatoes cultivated by tissue culture method are investigated. After preparing the lateral buds and sterilizing, were cultured in the MS medium. For the effect of salinity, concentrations of 0, 25, 50, 75 and 100 mM NaCl have been used. After the growth of buds, the leaves were sampled and the photosynthetic pigmentation, soluble sugars, proline, protein, and other characteristics were evaluated. The results show that salinity reduces photosynthetic pigmentation. The amount of protein, soluble sugars and fresh weight have also been reduced with salt stress, but the amount of proline has increased somewhat due to salinity, which is in response to salinity stress.
