摘  要：
利用热红外成像远程动态控制系统,实时检测非洲菊单支花和花束的舌状花瓣、管状花瓣、茎秆在真空预冷过程中的温度分布和变化,并对冷藏后瓶插期间切花的鲜质量变化率、气孔导度和蒸腾速率进行分析。实验发现,在相同降压速率、冷却时间条件下,单支花和花束不同部位的降温速率和瓶插指标均有明显差异(P<0.05),单支花的预冷终温平均比花束低11.2℃,瓶插寿命比花束长1.7 d。

摘  要：
The temperature distribution and variation of the ligule-shape petal,tubular petal and stem of individual and bunches of cut gerbera during vacuum cooling was measured by thermal infrared imaging.Relative fresh weight,stomatal conductivity and transpiration were analyzed during vase period.The results showed that the temperatures and three indexes were marked differently(P<0.05).The average precooling end-temperature and vase life of individual flowers were 11.2℃ lower and 1.7 days longer than bunches of flowers respectively.This research has important value in the determination of pre-cooling end-temperature,the optimization of cooling processes and the evaluation of pre-cooling effect of different amounts of cut flowers.
