 note = {In northern regions such as Hokkaido (Japan), sugar beet seedlings soon after germination often suffer from extensive frost damage in spring, resulting in serious loss of yield. Enhancement of freezing tolerance at the early seedling stage is necessary for sugar beet cultivation. However, little is known about physiological responses of sugar beet to low temperatures and the ability of sugar beet to acquire freezing tolerance. Cold acclimation is enhancement of freezing tolerance by exposure to low, nonfreezing temperatures. In order to investigate the physiological responses of sugar beet (Beta vulgaris L.) seedlings at the cotyledon stage to low temperatures, we analyzed contents of soluble carbohydrates in cotyledons during incubation at low temperatures. The total amount of soluble carbohydrates remarkably increased during incubation for 7 days at 5℃ or 10℃, though only a slight increase or no increase was observed at 15℃ or 20℃. Identification of the individual components of carbohydrates revealed that the amount of maltose was two-times larger than that of sucrose in sugar beet cotyledons treated at 5℃. This finding will facilitate an understanding of the physiological response of sugar beet seedlings to a low temperature and the ability of sugar beet seedlings to acquire freezing tolerance.},
