Abstract
Seeds of barley (Hordeum vulgare var. dolma) were subjected to heat shocks ranging from 30-90oC for 1-6 hours duration. Heat treatments up to 60oC for 3 hours stimulated the growth of seedlings as evident by increased seedling height which is due to the synthesis of special type of proteins called “Heat Shock proteins”. Presence of heat shock proteins is confirmed by giving various temperature shocks to the growing seedlings at different temperature ranging from 30-60oC for 1-7 hours and there is decrease in the rate of seed germination and seedling growth at higher temperature.
