| 中文摘要 | 本試驗目的為調節文心蘭‘檸檬綠’品種開花期和提高花序品質。6月除芽後,自10月到切花採收期,以架設於植物上方1.7 m之400 W高壓鈉燈,採投射方式於落日後連續延長電照,分為2小時與燈水平距離4.5及9.0 m; 3小時與燈水平距離4.5、9.0及13.5 m;4小時與燈水平距離4.5及9.0 m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1分枝長度和分叉數。各個處理(2小時、4.5及9.0 m/3小時、4.5、9.0及13.5 m/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%。整體而言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。 |
| 英文摘要 | The purpose of this experiment was to regulate flowering period and to improve inflorescence quality of Oncidium Gower Ramsey 'Honey Angel]. New buds of all plants emerging in June were removed. From October to the time of harvest, 400W high pressure sodium lamp as supplementary lighting started from sunset .The lamp was setup at 1.7 m height above the plants. The four lighting period treatments were designed due to the different horizontal distances from the lamp in which 4.5 m and 9.0 m distance with lighting for 2 hours, 4.5 m, 9.0 m and 13.5 m distance with lighting for 3 hours, 4.5 m, 9.0 m for 4 hours and the control (no supplement lighting). The Results showed that these lighting tgreatment after sunset could delay flowering period. Under 2-hours lighting, the flowering period of the treatment was delayed to coming February to 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 remaind in December to Fobruary next year. The cut flower quality was also improved by lighting treatment, as the length of flower stalk, flower part, the lowest branch and branch number of flower stalk were increased. The proportion of grade A was 10, 30, 46.7, 46.7, 43.3, 23.3, 36.7 and 0% respectively via 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. It concluded that the new bud removal on June with high pressure sodium lamp supplement lighting after sunset could be available to delay the flowering period and improve inflorescence quality of "Oncidium" Gower Ramsey 'Honey Angel'. |
