Spraying of gibberellins on juvenile conifers hastens the maturity period and thus leads to early seed production.
Differentiation, Dedifferentiation and Redifferentiation
-
In tissue culture experiments, leaf mesophyll cells are put in a culture medium to form callus. This phenomenon may be called as:
Differentiated cells regaining the capacity to divide is dedifferentiation.
The living differentiated cells, that by now have lost the capacity to divide can regain the capacity of division under certain conditions. This phenomenon is termed as dedifferentiation. Same occurs in tissue culture of leaf.
That is every question in Plant Growth and Development for this filter.
