In this context, interest in the sizes of fusiform cambial initials is justified, as a directing factor on the morphologies that can be produced: because all axial cell types in secondary xylem as well as phloem are ultimately derived from fusiform initials, there is a limit to the ontogenetic independence between cell types.
Vascular cambium activity in primary xylem was intense; the fusiform initials were long, radially flattened and tangentially tapering with overlapping ends.
According to our results, it can be concluded that the crystals in the secondary xylem correspond to those deposited in the fusiform initial cells of the vascular cambium.
