摘　　要：以6个大丽花品种‘Heat Wave’、‘New Baby’、‘Parc Rincess’、‘My Love’、‘Onesta’、‘Fuzzy Wuzzy’为研究材料,对其进行催芽分根、嫩茎扦插,比较不同品种的分根系数及扦插生根率。结果表明:(1)子根纺锤形,辐射状排列的‘Heat Wave’分根繁殖系数高,为6-8;子根椭球形、不规则排列的‘Onesta’分根繁殖系数低,为2-3;(2)嫩茎扦插20天后,各品种生根率均在65%以上,不同品种间存在显著差异,‘My Love’最高,为86.02%,‘Heat Wave’则最低,为65.95%,大丽花适宜采用嫩茎扦插进行繁殖。6 kinds of Dahlia pinnata varieties：‘Heat Wave＇,‘New Baby＇,‘Parc Rincess＇,‘My Love＇,‘Onesta＇,‘Fuzzy Wuzzy＇were researched as materials, taken on the force sprouting and split root、young stem cutting, compared ramet coefficients and rooting rate. The results showed that ：（1） ‘Heat Wave＇ had a high propagation coefficient（6-8）of spliting toot, whose second tuberous root were fusiform and arranged radially; ‘Onesta＇＇s propagation coefficient was low（2-3）, whose second tuberous roots were ellipsoidal and randomly arranged;（2）After cutting 20 days, the rooting rate of the 6 varieties were all over 65%, there was a significant difference among them, the highest was ‘My Love＇, 86.02%, and the lowest was ‘Heat Wave＇, 65.95%, so young stem cutting was suitable being taken in Dahlia pinnata propagation.
