This is a process similar to that which occurs in bamboo, which also have stems that lengthen primarily via intercalary meristem growth (Judziewicz et al.
The intercalary meristem is situated at the basal portion of the blade, near the junction with the pneumatocyst, and new tissues are constantly moved along the longitudinal axis of the blade (Hoek et al.

At the base of the blade and at the base of the sheath of grasses, for example, an intercalary meristem provides continuing mitotic activity long after the leaf is fully developed.
As the leaf develops, cell division occurs at two locations: the upper intercalary meristem at the base of the blade and the lower intercalary meristem at the base of the sheath (Figure 2-5).

In general, traits such as the main stalk total length, main stalk internode length, uppermost lateral branch length, and lowermost tiller length, which reflect activity of the intercalary meristem, tended to be positively correlated with each other.

The QTL located on LG 5 was also shown to affect the uppermost lateral branch length, a trait also involved in the elongation of the intercalary meristem.
The mode of action for gibberellic acid inhibitors like TE involves accumulation of active ingredient molecules at the intercalary meristem region, subsequent inhibition of gibberellin biosynthesis, and slowing of cell expansion in sheaths and basal regions of leaves (Kaufmann, 1986).
The internodes of the main stalk begin to elongate after tassel differentiation (and after axillary meristem differentiation) through the formation of new cells by an intercalary meristem located near the base of each internode above the first (Kiesselbach, 1999).
Within a growing internode, the younger, undifferentiated tissues are near the intercalary meristem at the base of the internode and become progressively more developed and mature higher up the internode.
