The Stone Fruit Physiology program at WSU has investigated tree fruit hardiness for nearly two decades. The webinar on Oct 29 covered recent research highlights and provided a demonstration of cold damage assessment. This is the second video of a four-part series from the sweet cherry cold hardiness webinar. In this video, Sweet cherry cold tolerance, dormancy, and floral development, Jonathan Magby, WSU PhD candidate in the Horticulture Department, gives a research update on sweet cherry cold tolerance, dormancy and floral development for 30 different genotypes.
