萬代蘭是臺灣新興之花卉作物，目前多作為切花外銷日本。萬代蘭Pachara Delight 'Blue'、Kulwadee Fragrance 'Black' 栽培於臺南地區設施內一年四季均可抽梗開花，唯冬季低溫期產量較少。萬代蘭花序生長呈一S 型曲線，花序發育與花梗生長速率顯著受季節溫度影響，冬季低溫時花梗生長較慢且較晚開花。夏季採收之切花經低溫11℃儲運後易發生寒害，且瓶插壽命亦較短，保鮮管液中添加氯化鈣則可降低寒害情形；而冬季採收之切花，儲運後較不會發生寒害且有較佳之瓶插壽命。
Effects of Season and Temperature on Vanda Cut Flower Production and Storage in Tainan
Yang, Y. and W. C. Hu
Vanda is a newly developed flower crop in Taiwan, and is exported to Japan as cut flower. Vanda Pachara Delight 'Blue' and Kulwadee Fragrance 'Black' grow in Tainan, could produce spiking flower all year round in the green house, but the cut flower production was less during cold winter season. Growth of Vanda flower stalks was a S type curve. Inflorescences development and stalk growth rate were significantly affected by season and temperature. Vanda flower stalks grew slowly and flowered lately in cold winter. Cut flowers harvested in summer were seriously chilling injured after storage at 11ºC, and had shorter vase life. Tube solution containing CaCl2 could lesson chilling injury. In the other hand, cut flowers harvested in winter had less chilling injury and longer vase life.
