Abstract
本研究利用Den. Lai's Lovely Momo一年生以上營養繁殖株，以人工合成之藥劑（代號T）配合適當溫度條件，可達良好的催花效果，可提高總花朵數達21朵、增加可開花節數達5節，每節花數平均4.4朵，隨處理濃度越高，花朵數越多，花朵橫徑越小，畸型花出現的機會增加。處理環境方面，於較溫暖的B溫室下進行處理，約可縮短到花日數20日，在葉月碳氮比分析方面，利用Dol. Lai's Yukisakura為材料進行催花處理後，可觀察到第l周即有明顯的可溶性糖類上升，應與花芽創始有關，第2周後可溶性糖含量持續下降，可推測是用於花序之形成與發育。未來可配合適當植株成熟度、施用濃度及溫度環境，應用於春石斛蘭產期調節體系，增加市場競爭力。
This research was conducted to use artificial drug T with appropriate temperature to induce flowering of Den. Lai's Lovely Momo older than one-year. Drug T promoted floral buds efficiently; it could increasing flower number to 21, nodes with flower to 5 nodes, average of 4.4 flowers per node. The higher the concentration of T, the more flowers would be, but diameter of flowers would decrease and also got higher frequency of malformed flowers. As regards temperature effects, treatment conducted in warmer greenhouse B could shorten days to flowering ,approximately shorten 20days. Den. Lai's Yukisakura was also used to analyze level of Nitrogen and total suspended solids (TSS) after flower induction treatment. After plants treated for one week, TSS level were obviously increasing which was presumed to correspond to flower initiation. By the second sampling (the second week ), the total TSS of leaves decreased continually, it was presumed to be used for inflorescence formation and development. In the future, treatment modified with drug T at appropriate plant maturity, concentration and suitable temperature, it could be apply to production regulations of Dendrobium pot flower and to improve competition of Taiwan dendrobium in product markets.
