영문 초록

These experiment was carried out in order to study the seedling growth and the frequencies of M₂chlorophyll mutations on various moistured barley seeds which were heated as pre-irradiation treatment. Youngwol-yukgak was used as a material variety. Some results obtained are summarized as follows; 1) Reduction of seedling height, as criterion of biological injury, was greatly appeared due to irradiation only compared with pre-irradiation heat treatment. 2) The growth of seedling was more sensitive than that of root especially in low moistured seeds. 3) Pre-irradiation heat treatment at 60-70℃ for 5 hours markedly increased the chlorophyll mutation frequency.
