Only 1O-day pretreatment of germinated seeds at 5℃ or 10℃ was enough to enhance the floral bud differentiation in the spring variety'Duanye 13', whereas at least 20-day pretreatment was required for the promotion of floral bud differentiation in the winter variety'Yidianhong'. Non-vernalized'Duanyi 13'plants flowered 70 days after transplanting in a warm (above 15℃) and long photoperiod (16h) growth condition, but non-vernalized 'Yidianhong'plants did not flower 90 days after transplanting in the same growth condition as'Duanye 13'.
