INDUCTION OF JUVENILITY AND ROOTING OF SOME WOODY ORNAMENTALS
In experiments between 1978 and 1989, ornamental members of the Cupressaceae family and Tilia tomentosa displayed more or less clearly distinguishable histological and morphological marks in their juvenile and adult (sometimes also in transitional) stages of development, the juvenile always being the better rooters. Adult specimens of the above mentioned plants could be reverted to the very juvenile stage by vegetative propagation, shading, etiolation, changing the position of shoot, or other treatments. The first new leaves, however, retained their adult shape and only the further, entirely newly initiated ones began to display transitional or juvenile characters.
