Stem-Shoot system in wheat

Wheat stem generally possesses height from 60-70cm (in case of three gene dwarf verities) to 125cm (tall varieties). The stem of wheat plant is round or cylindrical. In most varieties of the bred wheat the stems are hollow, accept at the nodes where they are solid but in a few varieties of durum wheats the internodes are completely filled with the soft pith. There are 5 - 7 nodes on the stem. Stem is solid on nodes and hollow in between the internodes. Maximum portion of wheat is covered with leaf sheath. Stem is often glabrous or some times it is hairy.
