中文摘要 | 本試驗探討以加馬射線照射鬱金香(Tulipa gesneriana L.)鱗莖及生長抑制劑處理以控制株高,提昇盆花品質之效應。加馬射線照射劑量分別為0、2.5、5、7.5及10格雷(Gy)五處理。試驗結果顯示,照射劑量愈高,其抑制株高之效應越明顯;以5Gy處理之株高22cm較符合最佳盆花品質標準。生長抑制劑處理,包含paclobutrazol、uniconazole及chlormeguat三種生長抑制劑及各三種濃度,分別以鱗莖浸漬,土壤灌注及葉面噴施等三種處理方法。結果顯示paclobutrazol處理之最適濃度浸漬法為5ppm,灌注法為12.5ppm,噴施法為25ppm。uniconazole處理,浸漬法為5ppm,灌注法為10ppm,漬施法為20ppm。chlormeguat處理,在浸漬、灌注法均無顯著效應。 |
英文摘要 | An experiment was conducted to determine the effect of Gamma-irradiation and growth retardants on the plant height and flower quality of potted tulip. Gamma-irradiation was applied at dosages of 0, 2.5, 5, 7.5 and 10 Gy, the results showed that the higher the dosage treated the shorter the plant height. The optimum dosage was 5 Gy because it controls the plant height about 22 cm and near the best quality. The growth retardants include paclobutrazol, uniconazole and chlormeguat, all treated in three concentration by bulb dip、drench and spray three methods. Results showed the optimum dosage for paclobutrazol were 50 ppm for dip, 12.5 ppm for drench and 25 ppm for spray. The optimum dosages for uniconazole were 5 ppm for dip, 10 ppm for drench and 20 ppm for spray. The dip and drench method were not able to control the plant height of the tulip pot-flower in chlormeguat. |
