摘要

本試驗旨在探討盆徑及摘心對盆菊（Dendranthema x grandiflorum（Ramat.）Kitam.）紅玉品種生育之影響，以評估小型盆菊最適之盆徑大小及摘心程度。摘心處理採留3、5及7節等三種處理，盆徑則採3、6及9 cm等三種處理。試驗結果顯示，摘心處理以留5及7節者的株高較高；始花天數以留7節之處理最快，次為留5節分別為62天及68.6天。盆徑試驗之結果顯示，株高、展幅及側枝數均以盆徑3 cm之處理最小，9 cm最大；始花天數以盆徑9 cm之處理最快為59.5天，盆徑6 cm之67.5天次之，盆徑3 cm之73.7天。盆徑及摘心處理對側枝數之交感效應顯著，在3公分盆中留3節處理其側枝數較留5節及7節少，而在9公分盆中留3節處理則比留5及7節多。株高比盆高之比值以9 cm盆3種不同摘心處理均低於2，外觀品質佳。

The Experiment was conducted to evaluate the effects of pot size and pinching on growth of pot mums. Three treatments of pinching including 3, 5 and 7 nodes left and three treatment of pot size with 3, 6 and 9 cm in diameter were adopted. The results showed that plant height was higher by pinching with 5 and 7 nodes left, lateral shoot numbers obtained the most by pinching with 7 nodes left, moreover, days to flowering was the shortest by pinching with 7 nodes left. In respect to the effect of pot size, plant height, plant width and number of lateral shoots obtained the highest in 9 cm diameter and smallest in 3 cm diameter. The days to flowering were also the earliest in 9 cm diameter. The number of lateral shoots was significantly application pinching x pot size interaction. The plant height to pot height ratio below 2 in 9 cm pot for 3 pinching treatment evaluated as the most better.
