Abstract: Studies on the effects of salinity and temperature at germination and seedling growth stage of Corn cv. Sunahry were carried out. Water uptake by seeds was directly proportional to temperature and inversely to salinity stress. Decrease in temperature and increase in salinity, decreased and delayed the initiation of germination. Optimal temperature for germination and growth was 30°C. There was a direct relationship between growth and osmotic potential of the medium. Chloride type of salinity was more deleterious than sulphate, both at germination and growth stage. Above optimal temperature an interaction between temperature and salinity was observed.
