Abstract
Flower formation in higher plants is a very complex process controlled by genetic as well as environmental factors (for review see e.g. Bernier, 1988). Although it is an integrated process, two major phases can be recognized: floral evocation and development. The term “evocation” designates the transition of the vegetative apical meristem to a “floral” meristem — that is a flower primordium generating meristem — following stimulation by internal and/or external “signals”. After this initial event the phase of floral development follows, starting with the appearance of floral primordia and ending with the mature flower composed of functionally and structurally distinct organs. During this process the type, number and position of the organs constituting the flower is strictly regulated. How is this achieved and what are the underlying mechanisms? The study of morphogenetic mutants displaying various types of abnormalities could be a first step to answering these questions.
