  風鈴花‘冠軍’切花品種在秋季播種,經生長箱涼溫育苗一個月,可以在台灣冬季生產切花。分別以株距20、30和40公分栽培風花切花品種 ‘冠軍-鮮桃’,其主枝和側枝的切花品質彼此間並無差異,但以株距30公分栽培較佳,可增加切花枝數。風鈴花可以利用電照處理來控制花期,‘冠軍-天藍’品種在定植後第7週和第9週進行電照處理,其盛花期分別是在第15週和17週。風鈴花在抽苔前做挖心處理可以增加側枝的長度、莖粗、鮮重和花朵數,提高切花的品質,另外挖心處理會增加50公分以上的側枝數,也就是會增加切花枝的數量。

Feasibility of the Lowland Cut Flower Production for Campanula Medium L. in Taiwan

Chen, C. J., W.C. Sun. and W.J. Hu

Abstract

   The cut flower cultivar ‘Champion‘ of Campanula medium L. could be germinated at 20℃ in a growth chamber for one month and grown in the field in autumn. It could produce cut flowers during winter in Taiwan. There is no difference in cut flower quality of main or lateral inflorescences when the planting distance were 20, 30 or 40 cm. It could produce more cut flowers when the planting distance was at 30 cm due to more branch inflorescences. The flowering period of Campanula medium L. was evaluated by night break. Night break at 7th and 9th weeks after planting the cultivar ‘Champion-Blue‘ flowered at 15th and 17 weeks. Pinching shoot tip before bolting increased the numbr and quality of cut flowers, such as length andnumber of lateral branches, stem thickness, fresh weight and number of the cut flowers.
