The snapdragon (Antirrhinum majus. L.) cv. 'Maryland Pink' and 'Light Pink Butterfly II ' were grown using two methods of raising seedlings and four night temperature settings for pinching cultivation in winter. For both cultivars, the flowering of the second node shoots was earlier, and the yield of cut flowers was increased using the method of raising seedling without temporary planting. A suitable night temperature for cut flower production of'Maryland Pink'was suggested to be a minimum of 11℃ starting from the middle of November. The largest yields of cut flowers of 'Light Pink Butterfly II' was obtained when the plants were grown under a night temperature over 11℃ starting from the middle of November, then increased to 16℃ from the middle of December. But the stem length of 'Light Pink Butterfly II' were shorter when the plants were grown under a night temperature of 16℃.
