　　 本研究於彰化縣大村鄉臺中區農業改良場 ( 平地 ) 及南投縣臺大山地實驗農場春陽分場 ( 海拔 1,100 m) ，測試 60 個菊花栽培品種及選育營養系。其中 23 個對春夏季高溫期之開花反應，有 15 個參試品種 ( 系 ) 於臺中區農業改良場三月份至八月份間種植可以開花。依臺中區農業改良場六、七、八月種植之二連續月份開花日數差異，將參試菊花之開花反應分為三群。第一群有 12 品種及選育營養系，其花下節數多、且開花延遲達 20 天以上；第二群有 4 品種及選育營養系，開花延遲達 10~20 天；第三群有 7 品種及選育營養系，開花延遲達 10 天以下。

關鍵字： 菊花，開花，熱延遲。

　　Flowering responses, in terms of days to flowering and number of nodes below the flower, were studied in 23 cultivars or breeding selections by planting monthly at Taichung District Agriculture Improvement Station (lowland) and Chung-Yang farm (altitude 1100m) in spring and summer, respectively. Fifteen out of 23 cultivars or selections flowered when planted monthly from March, 1999 to August, 1999 at lowland. Three groups can be classified according to their differences of days to flowering between two successive months from June to August. The groups I consisted of 12 cvs. or selections, which flowering was prevented or delayed for more than 20 days. Groups II contained four cvs or selections, which could flower but with heat delay for 10 to 20 days. In the group III, there were seven heat-tolerant cultivars or selsecions with heat delay fewer than ten days.

Key words: chrysanthemum, flowering, heat delay.
