One of the components that influences yields in grapevines is the number of berries that set and mature on each cluster, or "fruit set". Each flower cluster contains many individual flowers, each of which has the potential to become a grape. However, not every flower will successfully pollinate or develop a healthy embryo and the surrounding tissue that becomes the fruit that we want.

This article covers some of the factors that influence fruit set in grapes and summarizes practices that growers could use to influence set. It was originally published in the June 2013 issue of the Finger Lakes Vineyard Notes.
