蒐集之孤挺花商業品種共34 品種，進行栽培生育調查，結果篩選出單瓣品種#199、#75 及#105 及重瓣品種#211、#148 與TSS1 等6 品種適合做切花生產。在防雨設施具遮蔭網室內栽培6 品種孤挺花，其花莖長度較露天及防雨網室栽培為長，以#199 及#211 品種表現較佳。將TSS1品種之花莖分三時期成熟度進行採收並比較切花之瓶插壽命，結果以stage 2 採收之花莖瓶插壽命較佳。不管任何孤挺花品種，只要切花先於預措液中30 分鐘，皆可促進切花儲運後之瓶插壽命，而在品種比較中則以‘Queen Silvia’之瓶插壽命較佳，整體瓶插壽命可達9.3 天，其次是‘Mega Star’，整體瓶插壽命可達8.7 天。孤挺花‘LO’若有先以C 液進行預措處理，經貯運7天後，整體瓶插壽命與未貯運之效果差不多，可維持切花瓶插品質。選擇適合切花之孤挺花單、重瓣各6 品種進行雙鱗片繁殖比較，結果各品種間具差異性，單瓣品種以以#210 表現較佳，每球小鱗球繁殖數為30.1 球、小鱗球平均重量為1.4 g；重瓣品種以以‘TSS1’表現最佳，每球小鱗球繁殖數為40.3 球、小鱗球平均重量為2.5 g。以雙鱗片進行組培量化繁殖，結果以N0B0 之處理在誘導率、總再生小芽數及增殖倍率之效果較佳，以N2T2 處理之效果最差；以小花梗為培殖體進行組培量化培養基測試，結果以含N4B6 之生長調節劑處理之總再生小芽數及增殖倍率最佳。孤挺花‘TSS1’種球進行不同栽培環境養球比較試驗，結果以不具遮蔭網室種植之種球其周徑及重量表現較佳。
34 commercial amaryllis varieties were collected and cultivated to evaluate as cut flower. The result showed that varieties of single-flowers including #199, #75, #105 and varieties of double-flowers like #211、#148 as well as TSS1 are suitable for cut flowers. These six cultivars of amaryllis were cultivated in shaded net-house with rainproof facility. The scape lengths of amaryllis grown in shaded-net house with rainproof facility were longer than those grown in open-field and rainproof net-house without shaded-net. Among all, cultivars #199 and #211 were better than others. Maturity of scapes of TSS1 was separated into 3 stages. Cut flowers of TSS1 of different stages were harvested and used to evaluate the vase life. The result showed that the vase life was longer when cut flowers were harvested at stage 2. Regardless of any amaryllis variety, the cut flowers pretreated with preservative solution for 30 minutes could improve the vase life after storage. Comparing the vase life of different varieties, ‘Queen Silvia’ was the better one with a longer vase life, lasting up to 9.3 days, followed by ‘Mega Star’ which vase life was 8.7 days. The vase life of amaryllis ‘LO’ after 7 days of storage was similar to the control group if pre-treated with preservative C which showed that quality of the cut flowers can be maintained. Comparing twin-scale multiplication in six varieties of single-flower and six varieties of double-flower, the results showed that multiplication were different depended on varieties. #210 was better in the six single-flower varieties, which have 30.1 multiplication bulbs and the average weight of bulbs was 1.4g. While ‘TSS1’ was the best in six double cultivars with 40.3 multiplication bulbs and the average weight of bulbs was 2.5g. As to propagation test by tissue culture, explants cultivated in N0B0 treatment showed the best induction rate, total number of shoots and proliferation rate while those in N2T2 treatment were the worst. When using the pedicels as explants, different PGR treatments were compared and the result showed that total number of regenerated buds and multiplication rate were the best when treated with N4B6. Comparing the effects of different environments on growing of bulblets ‘TSS1’, those raised in the unshaded net-house performed better in circumference and weight.
