本研究將春石斛Dendrobium Lucky Girl成熟株置於不同溫度與濕度下,黑
暗貯藏 28 日以模擬海運來探討海運可能之適當溫度與濕度。結果經 6、12 與 18℃
貯藏後,在一般溫室(日夜溫28/20℃)栽培到開花時,有葉率各為54%、49%與23%;
而未貯藏者為70%。貯藏濕度試驗於6與12℃貯藏下,將相對濕度控制於71%、85%
及99% RH,在6℃貯藏下,3個濕度處理之葉片品質都維持良好,到開花時有葉率
皆在82%以上。以12℃貯藏則深受濕度所影響,在 85% RH下,有葉率為87%,高
濕(99% RH)或低濕(71% RH)則各為50%與 36%。開花品質於6與12℃貯藏者,有
花節數比例為 52%-55%,18℃貯藏者較低,為 40%-43%,未貯藏者為 59%-67%。
每節位之花朵數為2.1-2.8朵;花序長度除了以18℃貯藏者小於10 cm,其他以6與
12℃貯藏者都大於 12 cm。植株經過貯藏後,盆花壽命約為 5 週,未貯藏者約為 6
週。12℃貯藏會縮短催花日數,其始花日數為 71-75 日,未貯藏者為 80-82 日。綜
合這些結果,顯示 Lucky Girl 春石斛若要海運歐美,維持葉片品質較為困難,以 6
與12℃貯運較適合,但以12℃貯運則需將相對濕度維持於85%左右。
Mature plants of a nobile dendrobium, Dendrobium Lucky Girl were stored at 6, 12 and 18 for 28 ℃
days as a simulation of marine shipment and then the plants were cultivated in a greenhouse at day/night
temperature of 28/20 . ℃ When the plants began to flower the percentages of nodes with leaf were 54%, 49%
and 23% for the plants stored at 6, 12 and 18 , respectively, as compared with 70% in the control without ℃
storage. Another group of plants were kept at 71%, 85%, and 99% RH when stored at 6 and 12 . More than ℃
82% of leaves remained intact on the three humidity treatments when stored at 6 . ℃ High leaf retention
occurred in plants at 85% RH when stored at 12℃. There were 52% to 55% of nodes that produced flowers
in plants stored at 6 and 12℃, as compared with 40% to 43% when stored at 18 , and 59% ℃ to 67% in the
control. There were 2.1 to 2.8 florets in each node of stem. The floret diameter was 4.5 to 4.9 cm. Plants
stored at 6 and 12℃ produced 12 cm or longer inflorescences, while those stored at 18℃ had 10 cm or
shorter inflorescences. The longevity of the flower was 5 weeks approximately, as compared to 6 weeks in
control. Plants stored at 12℃ flowered on days 71-75 after cultivation in the greenhouse while the unstored
plants took 80 to 82 days to flower. Results show that the suitable storage conditions were 6 ℃ or 12 with ℃
the relative humidity controlled at 85% for exporting Dendrobium Lucky Girl plants by marine shipment.
