Extreme temperature events have resulted in annual insurable losses exceeding $80 million for the U.S. apple and pear industry for the last five years. These temperatures are forecast to increase leading to more frequent extreme temperature events. Our knowledge of apple and pear responses to hot and cold temperature extremes is based off older varieties, and is insufficient to assess current and future risks for newer varieties.
Our group is made up of 22 scientists from six states (WA, OR, MI, NY, PA, ME) and seven institutions (WSU, OSU, Michigan, Cornell, Penn State, U Maine, and USDA-ARS). We will work to better understand physiological responses of apple and pear trees to extreme temperatures, and seek to identify the genetic control of those responses. A better understanding of these processes can help growers choose the best varieties to grow.
We will also model historical and future risk of extreme temperature events and assess the economic impacts of climate change on apple and pear production. Models developed here can be used to assess shifting risk for growers and help inform capital investment and regional cultivar choices.
We will integrate project-based discoveries with applied research experiments to refine (or develop new) strategies that continue to help growers limit losses from extreme temperatures.
This project will help sustain the U.S. as a leader in pome fruit production and will prepare growers to better manage yearly risks of losses from temperature extremes that we will increasingly face in the future.
