Late Planted Winter Wheat: Growing Slowly But Surely
As with many growers we had a difficult time getting all of our winter wheat planted in the “Optimal” planting date window in 2009. A significant number of winter wheat acres across Wisconsin were planted under the full knowledge of reduced crop insurance coverage as well as reduced yield. Given that the 10-day weather outlook calls for reduced temperatures as well as potential flurries I was interested in the “state” of our November 13th planted winter wheat in Janesville WI. In Image 1. we see that the radicle, seminal roots, and coleoptile have all emerged. In wheat the radicle and seminal roots will be the first structures to appear. Only after the seminal roots and radicle begin to imbibe water will the coleoptile begin to elongate.
