摘要

本試驗之目的在探討施用勃寧激素和巴克素對繡球花「Bodensee」盆花品質的影響。使用勃寧激素100ppm可以增加繡球花「Bodensee」的植株高度、展幅及分枝性，巴克素的施用則明顯會抑制植株的高度、展幅、分枝長及花序直徑。根據理想盆花品質指數來評估，以勃寧激素100ppm處理者較佳。然而以外觀品質評估，則以勃寧激素100ppm及巴克素12.5ppm與對照處理相同。比較葉長與葉寬比值之結果顯示，勃寧激素及巴克素之處理均比對照組之比值大，顯示此兩種生長調節劑處理均具使葉長寬之比例增加之效應。

The objective of this study was to determine the effect of Promalin and Paclobutrazol on the growth and flowering of hydrangea ”Bodensee” (Hydrangea macrophylla (Thunb.) Ser.). Plants treated with Promalin at 100 ppm were significantly increased plant height and plant width and produced more number of shoots. In contrast, when plants treated with Paclobutrazol, plant height, width, number of shoots and diameter of inflorescence were significantly reduced. According to an evaluation based on the index of ideal pot flower quality, flowers of better quality were obtained from the treatment of promalin at 100 ppm. However, evaluation of appearance quality indicates that the quality of flowers in treatments of Promalin at 100 ppm and Paclobutrazol at 12.5 ppm was similar to that in control. Promalin and Paclobutrazol treatments had a greater effect on the ratio of leaf length to leaf width than control, which suggest that these two growth regulators would have an effect on increasing in ratio of leaf length and width.
