| 摘 要： | 以135个牡丹品种为试材, 归纳了花芽分化数量和梯度类型, 将同枝条的芽数聚类为少(3～4) 、中等(5～7) 、多(8～10) 3类; 花芽分化梯度为小、中、大3种类型。选取10个代表品种进行促成连续二次开花研究。结果表明, 花芽分化数量的多少及梯度的大小直接影响着开花次数, 花芽分化数量少、梯度大的品种不能同株促成连续二次开花; 花芽分化数量中等或多、梯度小的品种可以同株促成连续二次开花, 其中‘如花似玉’二次开花率达75% , 且两次开花品质均优良。

| Abstract: | The types of flower-bud differentiation in 135 cultivars of tree peonies(Paeonia suffruticosa) were identified and grouped as few(3-4),medium(5-7) or many(8-10) in number of flower-buds and small,medium or large in flower-bud differentiation gradient.Ten representative cultivars were chosen and investigated for their behavior in forcing successive secondary flowering.The results indicated that the flower-bud number and differentiation gradient were directly related with secondary flowering.The cultivars with fewer flower-buds and large differentiation gradient could not be forced for successive secondary flowering in the same plant,while the cultivars with medium-numbered or many flower-buds and small differentiation gradient flowered successively from January to April 2006 in the same plant by forcing.Among the latter,Paeonia 'Ru Hua Si Yu' had a secondary flowering percentage of 75% and produced good quality flowers during the primary and secondary flowering. |
