摘要: 【目的】 研究巴旦木花粉生活力,比较分析柱头可授性,为巴旦木人工授粉及相关研究和巴旦木良种选育提供理论依据。【方法】 以6个国内外巴旦木品种为材料,采用I2-KI染色法、离体萌发法法测定不同开花天数的巴旦木花粉活力的变化;用联苯胺-过氧化氢法测定巴旦木各品种的柱头可授性。【结果】 2种方法测定的花粉活力最大的为米星,最小的为麻壳;石头、尖嘴黄、鹰嘴的雌蕊在花开放后第2 d花柱长度达到最大且具有较强的可授性,米星、布特、麻壳的雌蕊在花开放第3 d花柱长度达到最大且具有较强的可授性。【结论】 采集花后第2 d的花粉对花后第2 d的石头、尖嘴黄、鹰嘴和第3 d的米星、布特、麻壳柱头进行人工授粉。

Abstract: 【Objective】 To provide a reference and theoretical support for the practice of artificial pollination and related research of almonds in the hope of providing a preliminary theoretical basis for the further smooth study of affinity pollination.【Method】 Six almonds varieties at home and abroad were used as experimental materials, I2-KI staining method was used to determine the changes of pollen activity of almonds varieties on different anthesis days, and benzidine hydrogen peroxide method was used to determine the stigmatization of almonds varieties.【Result】 The pollen vigor determined by the two methods was the largest and the smallest was Make; the pistil length of Shitou, Jianzuihuang and Yingzui reached the maximum and strong acceptability on the second day after anthesis, and the pistil length of Mission, Butter and Make reached the maximum and had strong acceptability on the 3rd day after anthesis , and the pistil length of Shitou, Jianzuihuang and Yingzui reached the maximum and strong acceptability on the 3rd day after anthesis, and the pistil length of Mission, Butter and Make reached the maximum and strong acceptability on the 3rd day after anthesis.【Conclusion】 The pollen collected on the second day after anthesis and the Shitou on the 2nd day after anthesis, Jianzuihuan, Yingzui and the Mission, Butter and Make stigmas on the 3rd day were artificially powdered, which provided the theoretical basis for the breeding of almond varieties.
