A statistical model to estimate and describe bud fruitfulness in Pinot noir in cool environments was developed. The study compared Pinor noir fruitfulness at three different sites during winter dormancy by light microscopy and actual fruitfulness established three weeks after budburst. Strong differences were observed between inflorescence primordia counts and actual inflorescence number after budburst. When examined microscopically, fruitfulness was evenly distributed along the cane with the exception of the first two nodes, which were significantly lower. In contrast, actual fruitfulness after budburst showed site differences and interactions between fruitfulness and node position. Cane starch was a significant predictor for inflorescence count.
