Although a very useful term, rejuvenation is biologically incorrect; the 

meristem is always juvenile.

 

 

How is the term "incorrect"? It's a descriptor of the physiological state
not of cellular type. Yes meristematic tissue is typically totipotent but
that is not what is being referred to in the term rejuvenation - it's the
new growth arising that has physiological characteristic of a seedling i.e.
non flowering, ability to root, erect stature etc etc. In comparison to
mature tissue that has flowered, is difficult to root and typically grows at
an angle.
