Generally, drought stress at seedling stage caused significant reduction in plant height, dry matter and leaf water potential while significant increase was obtained in stomatal resistance and root-shoot ratio. In addition to visual stress ratings, varietal differDEes were observed on these parameters. Two corn inbreds, MO17 and CM102 [Chong Ming 102], gave consistent reaction when subjected to both high temperature and gradual
