| Outline of Final Research Achievements |
To confirm the cause of snow tolerance variation in barley cultivars, concentrations of non-structural carbohydrate and stages of spike initiation were investigated before and after snow cover. It was indicated that low concentration of non-structural carbohydrate lead to heavier snow injure, that cultivars with earlier spike initiation were lower concentration of non-structural carbohydrate, and that there was the difference of concentration of non-structural carbohydrate depended on the combination of vernalization allele and photoperiod responsibility allele. It was revealed that the earliness of spike initiation was one of factors inducing the snow tolerance variation among barley cultivars.
