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.

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.
