摘　　要：以28个切花多头菊品种为试验材料,通过15个农艺性状测量和评分,将性状赋值64分作为品种入选值,筛选出耐低温优良切花多头菊品种18个,表现光反应周期和生育期短或较短,当花芽分化期经历日最低温8℃,花蕾形成和发育正常,切花品质符合市场需要,研究结果可为冬季切花多头菊设施栽培品种选择和组培苗繁育提供参考。Using 28 spray cut chrysanthemum varieties as experimental materials,through the measurement and scoring of 15 agronomic traits,and assigning 64 points as the threshold value for variety selection,18 cold-resistant excellent spray cut chrysanthemum varieties were screened.These varieties exhibited short or relatively short photoperiodic response cycles and growth periods.They were able to normally form and develop flower buds when exposed to the lowest daily temperature of 8℃during the bud differentiation phase,and the quality of the cut flowers meet market demands.The research results can provide references for the selection of varieties for winter spray cut chrysanthemum facility cultivation and the breeding of tissue culture seedlings.
