    摘要:

    利用熱紅外成像遠(yuǎn)程動態(tài)控制系統(tǒng),，實時檢測非洲菊單支花和花束的舌狀花瓣、管狀花瓣、莖稈在真空預(yù)冷過程中的溫度分布和變化,，并對冷藏后瓶插期間切花的鮮質(zhì)量變化率,、氣孔導(dǎo)度和蒸騰速率進(jìn)行分析,。實驗發(fā)現(xiàn),，在相同降壓速率、冷卻時間條件下,，單支花和花束不同部位的降溫速率和瓶插指標(biāo)均有明顯差異（P<0.05）,，單支花的預(yù)冷終溫平均比花束低11.2℃，瓶插壽命比花束長

    Abstract:

    1.7 d,。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 pre-cooling 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. 
