- 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.
