中文摘要 | 仙丹花(Ixora chinensis Lam.)以白色、綠色、黑色及銀色遮光網處理後,切花品質依切花採收月別而有差異。於1月至3月採收之切花以無遮光處理者之花莖最長,平均長約70.2公分,黑色網下之花莖最短,平均長約35.3公分,僅約為無遮光處理者的一半。於4月至6月時,亦以不遮光之切花花莖最長,平均長約64.43公分,黑色網下之花莖最短,平均48.92公分長。於7月至12月時,各色網下之切花長度差異不大。至於單株全年總產量,各色遮光網下之切花產量差異不大。但若以不同月別之切花產量比較,則不論何種顏色之遮光網,均以4月至6月時之產量最高,其中又以黑色網下之產量較其他處理之產量為高。7月至9月時,以不遮光對照組之產量最高,10月至12月時,則以銀色網下之產量最高,黑色網下之切花產量最低。1月至3月時,各處理之產量均低,其中又以綠色、銀色及黑色網下之產量最低。 於12月至3月之低光度、低溫期,夜間以人工補光處理,可使切花花莖加長,並略為提早開花;若以電熱線加溫,則不但可增加花莖長度、加大花序直徑、並可使其提早開花約28天。 |
英文摘要 | Shading with white, green, black and silver PE screens produced significant quality differences of the cut flower of Ixora during January to June. Plants grown under black PE screen produced the longest flowering shoots during July to September, while plants without any shading treatment produced the shortest flowering shoots. During October to December, there was no difference in the quality of cut flowers. During January to March, the longest flowering shoots were obtained under nonshading (average length 70.2 cm), while the shortest flowering shoos were under black screen (average length 35.3 cm). During April to June, the best flowering occurred under nonshading (average length 64.43 cm), while the shortest flowering shoots (average length 48.92 cm) appeared under black screen. The yield of cut flower showed insignificant difference under different shading treatments. However, the yield was lowest during January to March, and highest during April to June. Lightening with 60 W incandescent lamp from 11:00 pm to 2:00 am during late November to March resulted in a little longer flowering shoots, and shortened the days to flowering simultaneously. The effect of flowering date shortening and shoot length increasing was prominent if electric heater was introduced. The treated plants flowered 28 days earlier and flowering shoot length increased by 8.1 cm. |
