Formation of Cambium Ring

  • The intrafascicular cambium gets activated to perform the meristematic activity.
  • The parenchymatous cells of the pith rays that are present adjacent to the intrafascicular cambium dedifferentiate to become meristematic.
  • The meristem so formed through the dedifferentiation of the cells of the pith rays is called secondary meristem or interfascicular meristem.
  • The interfascicular meristem joins with the strip of intrafascicular meristem to form a complete cambium ring or vascular cambium.

Vascular cambium is formed by joining of intrafascicular and interfascicular cambia. Hence, it has components of primary as well as secondary meristem. It performs intra stellar secondary growth.
