摘　　要：为了探讨季节变化对切花月季花枝产量及品质的影响,以切花月季"卡罗拉"为材料,研究了不同季节切花月季的花枝品质及产量的差异。结果表明:在春秋两季,气温适宜",卡罗拉"生长良好,花枝品质优,产量适中;在夏季高温环境下,"卡罗拉"以营养生长为主,产量较高,花枝直径和重量增加,花瓣数减少,花蕾变小;在冬季低温环境下,以生殖生长为主,花枝直径和重量减小,花瓣数增加,花蕾变大。因此,低温胁迫对"卡罗拉"花枝品质的影响大于高温胁迫,在切花月季的冬季生产过程中应注意防范低温危害。In order to discuss the influences of seasonal change on yield and quality of flowering branch of Rosa hybrida,Carola was used as material to study the differences in yield and quality of flowering branch of Rosa hybrida between different seasons.The results indicated that in spring and autumn with moderate temperature,Carola grew well with high quality and moderate yield;in summer with high temperature,vegetative growth was governing for Carola,so the yield was relatively high,the diameter and the weight of flowering branch increased,the petal number decreased,and the flower bud became smaller;in winter with low temperature,reproductive growth took the advantage of the whole growth,so diameter and the weight of flowering branch reduced,the petal number increased,and flower bud became larger.Therefore,the low temperature stress influences quality of flowering branch of Carola more than high temperature stress,it should pay attention to avoid low temperature damage during production process of Rosa hybrida in winter.
