Abstract

藍紫色花為蝴蝶蘭中極罕見之花色，屬內可利用的種原不多，本研究前已透過屬間雜交成功育成Rhynchonopsis Tariflor Blue Kid ‘1030-4’，藍紫色表現強烈且無褪色情形，其開花習性屬夏開型蘭花，本研究探討光週期對其開花之影響，並期以人為方式調控花期，以達到商業生產所需。研究結果顯示，無論是延長日長或暗期中斷的長日處理均可促進R. Tariflor Blue Kid ‘1030-4’ 提早抽梗與開花，相較於自然日長處理，延長日長處理與暗期中斷處理分別提早45.5 d 與31 d 抽梗，兩個長日處理也較自然日長處理的植株分別提早34 d 與17 d 開花，延長日長處理對促進植株的抽梗與開花比暗期中斷效果更佳。開花品質方面，延長日長處理的花朵數 (15.6 朵) 顯著高於暗期中斷處理 (8.8 朵) 與對照組 (自然日長) (5.9 朵)，暗期中斷處理的花朵數雖然較對照組多，但兩者並無顯著差異，各處理之花徑並無顯著性差異。花梗長度以延長日長處理的植株最長 (47.2 cm)，其次為暗期中斷處理 (44.7 cm)，而對照組 (自然日長) 之花梗長度為最短 (37.2 cm)；花序長度亦呈現相同趨勢，延長日長處理之花序長度最長 (21.7 cm)，其次為暗期中斷處理 (20.1 cm)，而對照組 (自然日長) 之花序長度則低於其它處理組，為16.9 cm。各處理之平均單朵花壽命以延長日長處理最長，為20.1 d，其次為暗期中斷處理 18.2 d，而對照組自然日長之花朵壽命最短，為17.5 d。 Indigo Phalaenopsis is rarely seen in the commercial market and just a few germplasm are available in the genus for indigo flower breeding. Rhynchonopsis Tariﬂor Blue Kid ‘1030-4’ with a deep and nonfading blue color has been bred successfully by intergenic hybridization. The purpose of this study is to discuss the effect of photoperiod on the flowering of Rhnps. Tariﬂor Blue Kid ‘1030-4’, and plan to regulate artificially the flowering period for commercial production. The results of the study showed that long-day treatments including extending day length (ED) and dark break (DB) could promote the early stalk emergence and flowering of Rhnps. Tariflor Blue Kid ‘1030-4’. Stalk emergence of plants treated with ED and DB were 45.5 d and 31 d earlier than natural day length (ND) treatment, respectively, and flowering time that was 34 d and 17 d earlier than control, respectively. ED has a better effect than DB on promoting stalk emergence and flowering. The number of flowers in the ED treatment (15.6 flowers) was significantly higher than that in the DB treatment (8.8 flowers) and control (ND) (5.9 flowers), however, there was no significant difference between DB and control. There was no significant difference in the flower diameter among the three treatments. The longest stalk (47.2 cm) in that of ED, followed by DB treatment (44.7 cm), while the shortest stalk of the control group (ND) was 37.2 cm. The inflorescence length also showed the same trend. The longest inflorescence (21.7 cm) in that of ED, followed by DB treatment (20.1 cm), while the shortest inflorescence appeared in the control (16.9 cm). The longest longevity of a single flower in ED was 20.1 d, followed by DB treatment (18.2 d), while the shortest longevity was 17.5 d.
