Description
An experiment was carried out to clarify the relationships of growth characteristics and nonstructural carbohydrate (NSC) storages in relation to snow endurance in winter annual forage crops. Twenty one varieties of oats, barley and rye differing in snow endurance were sown in the fall of 1982 in the experimental field at Hokuriku Natl. Agri. Expt. Stn. Dry matter weights and concentrations and compositions of NSC were measured before snow fall. Dry matter weight of roots was in the same order as snow endurance among the three species while no significant differences were observed in those of tops among them. Roots should play an important role as a storage of reserves for snow endurance. As for the NSC concentrations of the three species, rye was the highest, oats was the lowest and barley was in between. NSC concentrations also differed significantly among the varieties in each species. The varietal differences in NSC concentrations were very large in rye. The highest were more than two fold over the lowest, but the concentration ranged less in barley and least in oats. The NSC storing capacities seemed to be of genetical factors in the species and varieties examined. The species or varieties higher in NSC concentrations were higher in snow endurance, indicating that high NSC genotypes may lead to snow endurance. High NSC strain may be available through plant breeding efforts.
