Gibeaut conducted the research on Bing, Chelan, Sweetheart and Regina varieties in The Dalles, Oregon, said Lynn Long, OSU extension horticulture specialist. He determined that most of the buds remained dormant throughout the cold temperatures of late February, though he found some visual signs of fatality among buds in the most advanced stages due to cold temperatures on Feb. 21.

The detailed results can be found on Gibeaut’s blog.
