217: Combating Climate Chaos with Adaptive Winegrape Varieties

Erratic weather like deluge rain, longer falls, and patches of drought disrupt vinifera’s adaptation to long-sustained winters. Jason Londo, Associate Professor of Horticulture in the School of Integrative Plant Sciences at Cornell AgriTech explains how big weather changes in the Pacific North East can cause vines to wake up earlier posing a risk to freeze or frost damage. By researching acclimation and deacclimation, Jason is working to breed and select varieties for enhanced cold resistance, drought resistance, pest resistance, plus good fruit quality. In the future, to reduce inputs in vineyards and increase economic sustainability we need to put the right grape in the right climate.
