| 为了充分掌握中原牡丹的开花授粉和结实习性，分析其育种利用价值，更好地为牡丹新品种培育提供参考。试验选取有一定育性的‘满园春光’、‘红斑白’和‘亭亭玉立’等11个中原牡丹品种为试材，分析自交、杂交、开放性授粉等不同方式的结实情况研究，结果表明：中原牡丹品种自交也有微量的结实，异花高于自花结实率，自交自花为0.31粒/朵，自交异花为0.76粒/朵；不同授粉方式下，人工杂交的结实率(9.4粒/朵)和坐果率(90%)均高于开放性授粉和自交；平均种子干重均在0.31～0.36g/粒，种子干重最大的为杂交组合‘彩菊×蝴蝶飞舞’(0.587 5 g/粒)。说明中原牡丹授粉方式是以异花授粉为主，人工定向杂交可有效提高其结实率。 |

| To comprehensively understand the flowering, pollination and fruiting characteristics of peony in Zhongyuan area, and to analyze its breeding and utilization value, providing a reference for the cultivation of new varieties of peonies. In this experiment, 11 peony varieties from Zhongyuan area, including 'Manyuanchunguang', 'Hongbanbai' and 'Tingtingyuli', were selected as test materials. The fruiting conditions were investigated using various methods such as self-crossing, hybridization, and open pollination. The results showed that self-crossing of varieties in Zhongyuan area had a small amount of fruiting, and the fruit-setting percentage of cross-flowering was higher than self-flowering, the setting percentage of self pollination during selfing were 0.31 grain/flower, and the setting percentage of cross pollination of selfing were 0.76 grain/flower. Under different pollination methods, the setting percentage(9.4 grain/flower) and the fruit setting rate(90%) of artificial hybridization were higher than that of open pollination and self-crossing, the average dry weight of seeds were 0.31~0.36 g/grain, and the largest dry weight of seeds(0.5875g/grain) of the hybrid combination was 'Caiju×Hudiefeiwu'. It is concluded that cross-pollination is the main method of pollination for peonies in Zhongyuan area, and artificial directional hybridization can effectively improve the setting percentage. |
