摘　　要：花芽分化是葡萄产量形成的生理基础。为了解葡萄不同节位芽发育的情况,本试验以6年生藤稔品种为试材,通过在枝条不同节位进行修剪并仅保留顶部2个芽的处理,研究了不同节位芽萌发新梢的开花及结果习性。结果表明,不同节位的修剪处理均不同程度地增加了结果枝的粗度和花序数,果穗和果实性状也有所提高。Floral differentiation of buds is the physiological basis of grape yielding.In order to investigate the bud differentiation at different nodes of grapevine branch,we used 6-years-old grapevine（Vitis vinifera L.cv.Fujiminori） as trial materials in this study,in which the branches selected were pruned at various nodes and only two buds kept at the top of them to be studied on their flowering and bearing.The result showed that the pruning treatment could not only increase the number of flowers per inflorescence and the diameter of fruit branch,but also improve fruit quality.
