Abstract
Studies on the germination of Hordeum jubatum seeds indicate that they were highly tolerant of salinities up to 1.0%, with little reduction in germination. Each increase in salt concentration did, however, delay the time of germination. Seedling growth proved to be more sensitive than germination to salinity stress, with newly germinated plants showing a decrease in size with each salinity increment. Results of growth studies were similar to those in germination tests; plants decreased in size with decreased osmotic potential of the salt solution. The germination stage and later periods of active growth were nearly equal in their ability to withstand salinity stress.
