Abstract
「台農4號一白雪」文心蘭為農業試驗所選育之白花文心蘭新品種，其花朵於開放後逐漸由黃色轉為白色，然而於慣行栽培下其唇辮無法順利轉白，造成生產與銷售之困擾。本計畫目的即為建立白雪文心蘭唇瓣之轉色調控技術，以解決轉色困難之問題。試驗結果發現白雪唇瓣花色受光照強度影響，光強度越高其唇瓣黃色著色程度也越高，因此適度增加遮陰即可促進轉白效果。「美白養液」則是針對白雪文心蘭所開發之轉色調控技術，目前已完整建立可應用於不同季節、產區及栽培設施之標準作業流程，包括採後處理法與花期處理法。藉由栽培設施之光控調整以及美白養液之搭配使用即可使白雪文心蘭唇辮順利轉為白色，確保切花品質與提升產業利益。
Oncidesa Tariflor Snow White ‘Tainung No.4-Snow White’ is a cultivar of TARI. Its labellum color would change from yellow to white after flowering, but the environment of conventional cultivation was not suitable for conversion of lip color. The objective of this research was to establish a flower color control technology to solve this problem. The result showed that lip color was affected by light intensity. Lip color would tend to get white under lower light intensity. So we could improve flower color by adding shading level appropriately. The operating procedure of how to use ‘Flower color control nutrient solution’ to whiten the lip color of Oncidesa ‘Tainung No.4-Snow White’ was developed, including postharvest operation and anthesis operation. So growers could improve quality of Oncidesa ‘Tainung No.4-Snow White’ cut flowers by controlling light conditions and using ‘Flower color control nutrient solution’.
