摘要: 目的】 研究葡萄花芽形态分化时间和各时期的特征,为解决葡萄大小年结果现象提供理论依据。【方法】 以葡萄新品种蜜光和宝光为试材,夏黑为对照,采用石蜡切片法对花芽分化过程的花芽分化形态进行观察和对比分析。【结果】 蜜光宝光和夏黑花芽分化均可分为未分化期、花序开始分化前期、花序原始体发现期、花序主轴期和花序第二穗轴期5个时期; 6月上旬到8月上旬为夏黑花芽的分化盛期(约60 d);6月上旬到7月中下旬和5月下旬到7月中下旬为蜜光( 约40 d)和宝光花芽的分化盛期(约50 d)。【结论】 蜜光、宝光和夏黑花芽分化进程各个时期的形态特征基本相同。夏黑花芽分化进程较缓慢,各阶段持续时间相对较长且各阶段互相重叠;蜜光和宝光花芽分化相对集中,分化进程相对较快。

Abstract: Objective】 The study aims to observe the initiation time of flower bud differentiation and the speed of differentiation in different grape cultivars in the hope of providing theoretical foundation for alternate year bearing. 【Method】 The paraffin section method was used to observe the bud structure in the process of flower (cultivars Miguang, Baoguang and Summer Black).【 Result 】 The results showed that the whole process of the morphological differentiation of flower bud could be divided into the undifferentiating stage, the early differentiation of inflorescence stage, the inflorescence anlagen appearance stage, the formation of the main axis of inflorescence primordium stage, and the second branching of inflorescence primordium stage. The peak period of flower bud differentiation of Summer Black , Miguang and Baoguang occurred between the early June and the early August(about 60 days), between the early June and the mid to late June (about 40 days) and between the late May and the mid to late June(about 50 days) respectively.【Conclusion 】 In general, the morphological characteristics were basically the same in each stage in the three cultivars. The process of flower bud differentiation was slower, the duration of each stage was relatively longer and the stages were more overlapped with each other of Summer Black than Miguang and Baoguang.
