摘　　要：葡萄产量与品质和花序数量、特点、结构等密切相关。葡萄品种资源众多,不同品种结实系数、花序着生节位以及花序的结构等存在差异,花芽分化的高低与修剪有关。为对葡萄花序有更好的认识,以及为更好地利用葡萄种质资源、葡萄育种亲本选择以及栽培管理措施的实施提供一定理论参考,本研究对205份葡萄种质资源的花序特点进行了调查分析。研究发现:葡萄花序类型有花序紧凑型、花序松散型、无卷须型、卷须紧靠花序型、卷须非紧靠花序型等,欧美杂种花序着生初节位分布在3和4,其结实系数为1或2。欧亚种初节位分布在4和5,其结实系数主要为1。抽生花序节位的芽比非抽生花序节位的芽大。花序增长速度在开花前7d时最大。The grape yield and quality is closely accociated to the number of inflorescence, characteristics. Nu- merous grape variety resources, different varieties of each new inflorescence slightly the living quantity, the joint po- sition, and the structure of inflorescence, these characteristics not only influence the grape harvest, also affect the use of the tree and cut way and other management measures. To better understand grape inflorescence, select elite grape germplasm resources and partenal lines for crossing, and optimize cultivation management,we systemically analyzed the inflorescence of 206 grape germplasm accessions. The result indicated that the inflorescence of flowers showed large variations, for instance, compact flowers, loose flowers, flowers without tendrils, tendril close to the flowers etc. European and American hybrid flower festival at the beginning of a spike in distribution in 3 and 4, one of branches of panicle number mainly for 1 or 2. Eurasian section at the beginning of a distribution in 4 and 5, one of branches of panicle number mainly to 1.
