Factors That Affect Fruit Set

Factors That Affect Fruit Set

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.

Katie Gold Named New Grape Pathologist

Katie Gold has been named as the new assistant professor of Grape Disease Ecology and Epidemiology at Cornell AgriTech in Geneva. Katie is currently completing her Ph.D. at the University of Wisconsin - Madison. Upon completion of her Ph.D., she will conduct postdoctoral research at the NASA Jet Propulsion Lab (JPL) in California from August 2019 through January 2020. While at JPL, Katie will gain experience with the latest hardware and software for remote imaging with future application to digital agriculture and grape production. She will begin her tenure-track assistant professor position on February 1, 2020 with responsibilities that are 60% research and 40% extension.

Her research and extension seminars were on the topics of "Hyperspectral systems for pre-symptomatic potato disease detection" and "Agricultural sensors in Grape IPM", highlighting some of the tools and approaches that she will bring to the position. Katie is already setting up collaborations for her grape work in New York and plans to attend the American Society for Enology and Viticulture - Eastern Section Meeting in Geneva this July.
