Abstract

The degree of saline tolerance of crops varies with species and varieties. Germination being a critical stage of plant growth, many investigators reported retardation in germination and growth of seedlings due to higher salinity levels. The varietal difference in saline tolerance will be a useful source of selection of tolerant varieties. Sorghum has been classified as a medium tolerant crop to salinity (Richards, 1954). Yet, only a meagre knowledge is available on the salt tolerance of South Indian Sorghum varieties. The present study is devoted to an investigation on the response of fivevarieties of sorghum to salinity in the early stage.
