Abstract

The progress and development of crops like potato are harmfully affected by increased heat stress throughout the world. Stress caused by increased heat adversely affects germination and seedling growth which result in a reduced crop development and yield. The present research was carried out to know the influence of heat stress on growth indices and physiological processes of potato (Solanum tuberosum L.). The heat stresses C- Control (25 °C); T1-45 °C, and T2-40 °C were applied in separate growth chambers to the plants, after 25 days from their germination. Increased heat stress considerably decreased the chlorophyll a and b pigments of potato plants. Increased heat stress reduced the growth of potato and resulted in a major reduction of the leaf relative water content, leaf fresh weight and leaf dry weight of potato. Proline and soluble sugar concentrations were evidently enhanced in potato plants when they were associated with increased heat stress.
