This study was carried out to investigate the effect of low temperature raising on the flowering and cut flower quality of Eustoma grandiflorum cv. Early Bicolor Purple from April 1995 to May 1996. Temperature of raising greenhouse was beyond the limit of rosette formation, mean 25degreeC or minimum 20degreeC, from the early of June to the early of September 1995. Low temperature treatment of seedlings, developed four leaves, at 12+-1degreeC for 30days, made it possible to harvest from the late of February to the late of April 1996. Cut flower quality of low temperature treated plants, represented by length and weight of cut flower, and number of flowers, was of equally high level to that of non treated plants.
