Abstract
The histological study of the de novo formation of shoot and root meristems from inter-nodal segments of Torenia fournieri showed that buds are formed exclusively from epidermal cells and roots from endogenous perivascular tissue. It seems that there are no particular epidermal cells which are preferentially involved in the initiation of buds. This study showed the different and apparently specific potentialities of superficial and endogenous tissues.
