(En)Summary: Evidence is presented of the production of stress proteins in response to high temperature and water stress in barley seedlings. A brief period at 37 deg Centigrade induced the production of heat shock proteins and increased the capacity of the seedlings to recover from exposure to higher temperatures (42-45 deg Centigrade). In particular, a 70 kD HSP was found. Novel proteins appeared after PEG induced water stress. Laboratory physiological screening methods were used for selection among genotypes. A lack of correlation among the response to physiological tests at different stages of growth led to the postulation that the genetic mechanisms of drought tolerance are independent and process-specific for each stage of barley developmentCollection: AGRIS Collection
