Ontogenetically, the monocot cambium originates from the primary thickening meristem (PTM), which is a region of actively dividing meristematic cells, located around the apical meristem and extending down the periphery of the stem, where this continuation of PTM is referred to as STM.

To simulate larval damage I used forceps to destroy either the single apical meristem or all visible axillary meristems.
The shrinkage of the internodes is caused by the inhibitory effects of PGRs on the division and elongation of the sub-apical meristem without restricting the function of the apical meristem, which is responsible for stem growth and extension.
In contrast, cytokinins have the opposite developmental role in the root apical meristem, where they control root meristem size via regulation of auxin distribution (which stimulates cell proliferation and maintains totipotency in the root apical meristem (RAM); Stahl and Simon, 2010; Ruzicka et al.
