中文摘要 | 本試驗旨在探討不同濃度的激勃素(Gibberellic acid)及巴克素(Paclobutrazol)對彩色海芋盆栽品質之影響。彩色海芋「Areis」及「Neroli」二品種塊莖於種植前,分別浸泡於50、100、200ppmGA3溶液中15分鐘並且以浸泡水為對照組,結果顯示GA3處理對兩品種均有促進開花效果,「Areis」品種以100ppmGA3處理的開花數最高,較對照組提高337%;「Neroli」品種以50ppmGA3處理開花數為6.0支/盆較對照組2.3支/盆高,與100ppm及200ppm處理沒有顯著差異。GA3及巴克素對彩色海芋「Black Magic」試驗,顯示GA3處理促進開花且達極顯著差異;以100ppmGA3處理可增加株高且達極顯著差異;巴克素處理顯著抑制株高生長且濃度愈高抑制效果愈強。 |
英文摘要 | In order to understand the effect of applying GA3 and Paclobutrazol on the growth and flowering of potted plant in Zantedeschia spp., Experiments were conducted during 1998. Tubers of 'Aries' and 'Neroli' were soaked in GA30 (water control), 50, 100, 200 ppm for 15 mins. The results showed that tubers treated with GA3 could promote flowering in both speices. 'Aries' treated with GA3 at concentration of 100 ppm obtained the highest flower number. The flower number from treatment of applying with GA3 50 ppm was 6.0 flowers/pot and significantly higher than that of check 2.3 flowers/pot in 'Neroli'. The flower number were not significantly different among treatments applied to 'Neroli'. In the experiment of applying GA3 combined with Paclobutrazol to 'Black Magic', the flower number of treatment with GA3 at 100 ppm showed that GA3 could significantly increase flower number. There was significantly difference in promoting flower number as well as plant height applied with GA3 100 ppm to 'Black Magic'. Paclobutrazol was effectively controlled the growth of plant height and the higher the concentration resulted the shorter in plant height. |
