中文摘要 | 於人工氣候室與梅峰(海拔2100公尺)研究溫度對繡球花花芽形成之影響,以建立繡球花在臺灣本土之花期調節基礎資料。於人工氣候室15/13℃處理24天後,植株莖頂已達分化五個花序原體階段。而20/15℃處理者,以分化五個花序原體或進入花序原體產生分枝階段。於78天後,25/20℃處理者僅有20%的植株進入花芽創始階段,30/25℃處理之植株仍處於營養生長。南投縣魚池鄉業者於1997年七月上旬運至梅峰高冷地之植株,經15-39天後花芽已創始。桃園縣新屋鄉業者於2001年七月將植株運至梅峰,結果植株經50-60天後花芽已創始;於八月運達者,經63-74天後達花芽創始階段。營養生長之繡球花的莖頂發育階段和莖頂直徑呈線性相關,當莖頂直徑為0.32-0.46 mm時,始迅速膨大並分化花序原體。 |
英文摘要 | Effect of temperature on flower formation of Hydrangea macrophylla ‘Leuchtfeuer’ was studied in phytotron and Mei-feng highland field conditions in order to establish the information of regulation of flowering in hydrangeas in Taiwan. After the 15/13℃ treatment for 24 days, the hydrangeas had inidtiated five primary inflorescence primordia, while the 20/15℃ - treated plants had initiated both primary and secondary inflorescence primordia. After treatments for 78 days, 20% of the 25/20℃ - treted plants had initiated inflorescences, while all of the 30/25℃ - treated plants remained vegetative growth. Hydrangeas, supplied by a grower at Yu-Chih area in Nantu, had initiated inflorescences in 15 to 38 days after plants' transferring to Mei-Feng in July 1997. Hydrangeas, supplied by a grower at Hsin-Wuhr area in Taoyuan, had initiated inflorescences in 50 to 69 days after transferring to Mei-feng in July, and in 63 to 74 days for those transferring in August 2001. Shoot apical diameter (<0.32 - 0.46 mm) was linearly related to the shoot developmental stage in the phytotron or highland field-grown vegetative plants, but after inflorescence initiation, the shoot apical diameter expanded rapidly. |
