A little later, however, the internodes elongate quite rapidly, pushing the nodes farther apart and lengthening the stem. Before this stage begins, buds appear at the lower nodes and develop by lengthening their internodes into full-sized stems along with the lengthening of the main stem. This is called tillering or stooging. Thus one seed normally produces several stems, sometimes as many as a dozen or more. The nu

A little later, however, the internodes elongate quite rapidly, pushing the nodes farther apart and lengthening the stem. Before this stage begins, buds appear at the lower nodes and develop by lengthening their internodes into full-sized stems along with the lengthening of the main stem. This is called tillering or stooging. Thus one seed normally produces several stems, sometimes as many as a dozen or more. The number of tillers produced depends upon several factors. Some varieties naturally produce more tillers than others. Thin seeding promotes the growth of a larger number of tillers than a thicker rate of seeding. Winter wheat usually tillers more than spring wheat. Poor or infertile soils retard the production of tillers. Thus it is seen that many more heads or spikes are pro- duced on a given area than there were kernels planted, the number depending upon the several factors above mentioned. The length of the stem, when fully grown, varies with the variety and soil. Some varieties grow only to 3 feet in height, while others under the same conditions may reach a height of 4 or 5 feet. Aside from the variation in the length of the stem, there is also found variation in the number of tillers, thickness of the stem wall, and in the number of nodes. In describ- ing or identifying varieties of wheat, the color of the stem, particularly that of the upper internode, is of considerable.
