Abstract
本試驗目的為調節文心蘭一檸檬綠品種開花期及提高花序品質。6月除芽後，自10月到切花採收期，以架設於植物上方1.7m之400W高壓鈉燈，採投射方式於落日復連續延長電照，分為2小時與燈水平距離4.5及9.0m；3小時與燈水平距離4.5、9.0及13.5m；4小時與燈水平距離4.5及9.0m及無電照對照組等處理。結果顯示，落日後連續延長電照可延遲開花期。花期以2小時電照處理可延後至隔年2至3月、3及4小時處理可調節至隔年2至4月，對照組則維持於當年12月至隔年2月。花序的品質也由落日後延長電照處理所增進，即增加花序總長度、花部長度、莖部長度、第一分枝長度和分叉數。各個處理（2小時、4.5及9.0m/3小時、4,5、9.0及13.5m/4小時、4.5及9.0,m/對照）之A級切花比例分別為10、30、46,7、46.7、43.3、23.3、36.7和0％。整體而官除芽配合高壓鈉燈電照處理可調節文心蘭‘檸檬綠’品種開花期並提高切花品質。
The purposes of this experiment were to regulate flowering period and to improve cut flower quality of Oncidium Gower Ramsey ‘Honey Angel’. New buds of all plants emerging in June were removed. From October to the time of harvest, 400 W high pressure sodium lamps were setup as supplementary lighting started from sunset. To obtain different light intensity, lamps were setup at 1.7 m height above the plants, at a space of 4.5 m, 9.0 m and lighting for 2, 3 and 4 hours. For 3 hours lighting treatment, an additional spacing treatment of 13.0 m was also setup.
The Results showed that supplemental lighting treatments after sunset could delay flowering period. Under 2-hours lighting, the flowering period of the treatment was delayed to February and March. Under 3-hours and 4-hours lighting treatments, the period was delayed to the coming February to April. As for the control, the flowering period remained in December to February next year. The cut flower quality was also improved by lighting treatment, the length of flower stalks, flower size, the lowest branch and branch number of flower stalk were all increased. The proportion of grade A cut flower was 10, 30, 46.7, 46.7, 43.3, 23.3, 36.7 and 0% for the following treatments, 4.5 m & 9.0 m for 2 hours, 4.5 m, 9.0 m &13.5 m for 3 hours, 4.5 m & 9.0 m for 4 hours, and the control, respectively. In conclusion, new bud removal in June in conjunction with supplement lighting after sunset from October could be employed to delay flowering period and improve cut flower quality of Oncidium Gower Ramsey ‘Honey Angel’.
