王裕權、張元聰、陳燿煌、王仕賢、吳慶杉。 2006。 洋桔梗育苗技術之研究。台南區農業改良場研究彙報 48: 47-59。
本試驗主要探討不同種苗來源、光源、苗齡及溫度等育苗條件對洋桔梗苗株生長及切花品質之影響。其中不同的種苗來源，對洋桔梗各種性狀影響較大，進口種苗的簇生率是 0﹪，高冷地育苗卻超過10﹪，株高和莖徑則三種種苗來源無明顯差異，節數與葉片數以進口種苗最多，但節間長與葉幅寬以高冷地育苗表現最佳。第一朵花高度以進口種苗的 69.8 c m最高，但花朵數不受種苗來源的影響，花徑也是進口種苗較大，而花梗長以平地冷房育苗的 16.6 c m最長，盛花期最晚。不同品種會影響洋桔梗的簇生率、株高、莖徑與葉幅寬，另外節數、節間長與葉片數則較不受影響。在開花品質方面，除盛花期外，第一朵花高、花苞數、花朵數、花徑與花梗長都會受不同品種所影響。種苗來源在株高上無明顯差異存在。 不同光源下育苗後對洋桔梗切花品質 有顯著差異存在。其中以冷陰極管 -綠光及白光育苗之株高及莖徑最佳。以12週苗齡其 簇生率最高 19.7%，其次為10週8.0%，最佳為8週8.0%。不同溫度處理以20/ 10℃ 處理 其 簇生率最低 4.6%，其次分別為25/ 10℃ 9.0%及30/ 10℃ 14.4%。
Studies on Seedling Technology of Eustoma
Wang, Y. C., Y. T. Chang, Y. H. Chen, S. S. Wang and C. S. Wu
In this research, we suggested that different sources of seedlings had more significant effects on growth and flowering characteristics of Eustoma . The percentage of rosettes was 0% and 11.1% in imported seedlings and highland seedlings, respectively. There were no difference among three seedling sources for height of shoots, diameter of stems, and numbers of flowers and flower buds. In imported seedlings, we got most numbers of nodes and leaves, most height of first flowers ( 69.8cm ) and most width in diameter of flowers. However, the best length of internodes and width of leaves was showed in highland seedlings. In lowland seedlings, there were the most length of flower stalks ( 16.6 cm ) and the latest days to full blooming stage.
There is no difference in growth characteristics of Eustoma in different cultivars. But, there were difference in the height of first flower, numbers of flower buds and flowers, diameter of flowers, and length of flower stalks except full blooming.
Through the different light treatment, characters had significant effect on growth of Eustoma . There was significant difference in plant height, and stem diameter by ‘ CCFL Green' and ‘ CCFL white' light. There is significant difference in the percentage of rosettes from the 12th through the 8th week seedling stage. There is significant difference in different vernalization temperature. But the lower vernalization temperature treatment ( 20/ 10 ℃ ) percentage of rosettes (4.6 %) batter than other treatment.
