The periderm (cork layer) is produced by the cork cambium, which appears after the first year of growth. The secondary phloem is produced by the vascular cambium, which appears after the first year of growth. The vascular cambium also produces the xylem, which makes up the sapwood. The heartwood is the innermost layer of wood, and it is formed from the older xylem. Therefore, the correct order is 1-5-4-2-3-6.
