Fluctuations in flowering time and cut flower quality due to changes in temperature in the Tohoku region (Japan) were investigated in a summer-to-autumn flowering-type cultivar (Iwa-no-hakusen) or an autumn flowering-type cultivar (Jinba) cultivar of chrysanthemum. After long day treatment, plants were grown under natural daylength, and high and low temperature conditions in a temperature gradient chamber (TGC), in which the air temperature was similar to that observed under field conditions.
