Teosinte X Corn

The ears are from F1 plants of teosinte X corn. Teosinte and these hybrids wait until the short days of Fall to start setting seed. I forget the number of hours of daylength they want. But to induce earlier bloom and beat the frosts, these plants had their daylength artificially shortened by being covered with an inverted trashcan early each evening (taken off later the next morning).
