Abstract
Blueberry production is increasingly threatened by extreme heat events in the Pacific Northwest. High temperatures during flowering reduce pollination and limit fruit development through direct damage to critical parts of the flower. Developing and ripe berries can also be directly damaged by extreme heat. The purpose of this publication is to describe both the conditions under which extreme heat can damage blueberry flowers and fruits and the likelihood of high temperatures occurring during critical developmental periods within Washington State. Spatial analogs of future heat stress and strategies to mitigate the negative effects of extreme heat are also reviewed. Information regarding future risks and mitigation measures will help the blueberry industry to protect their crop from the negative effects of extreme heat.
