AB  - 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
(<i>Solanum tuberosum</i> 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.
