Impact of Preharvest Weathering, Without Sprouting, on the Quality of Soft White Winter Wheat in the U.S. Pacific Northwest

Creator:: Smith, Jordan L.
Abstract:: When wheat is exposed to rain in the period before harvest, it sometimes causes the problem of pre-harvest sprouting (PHS). Wheat that undergoes sprouting has poor end-use quality and is less valuable. In recent years, the U. S. Pacific Northwest (PNW) has experienced increased summer showers sometimes causing widespread PHS....
