This is why control of growth and branching is of utmost importance
for the rose, like for other ornamental plants grown in pots.
Industrial horticultural production systems require an optimisation
of the production area, particularly in the greenhouse, resulting
in the densification of crops. These growing conditions favour leaf
expansion and branch elongation, with a risk of etiolation when
the overall climatic conditions are poorly controlled. However,
this excessive elongation of branches considerably depreciates the
