We investigated fluctuations in the fruit maturation period (from flowering to harvest), anthocyanin content, and reduced ascorbic acid content in strawberry (Fragaria×ananassa Duch.) depending on the differences in harvest time, and discussed their relationships with the cultivation environment (solar radiation, temperature). The fruit maturation period of ‘Nyoho’ and ‘Toyonoka’ decreased significantly as cultivation progressed. In both cultivars, the fruit maturation period had a high correlation with solar radiation and temperature, and in particular, a complete proportional relationship was observed between integrated maximum temperature and fruit maturation period, suggesting the possibility of predicting harvest dates using the regression formula. Although the anthocyanin content of ‘Nyoho’ was higher than that of ‘Toyonoka’, a difference in harvest time was scarcely observed between the two cultivars. Furthermore, the correlation between the anthocyanin content and solar radiation or temperature was significantly low compared with the fruit maturation period, but that in ‘Toyonoka’ tended to be higher than that in ‘Nyoho’, indicating the characteristics of both cultivars. The reduced ascorbic acid content was the same in both cultivars, significantly decreasing in the middle of the cultivation period, and its correlation with solar radiation and temperature fluctuated irrespective of their variations.
