Chronology of organogenesis and elongation periods of growth units (GU) of annual shoot over 1 year. a Organogenesis (dotted line) and elongation activity of each GU (solid line). b Periods of axillary productions (symbols: respectively cataphylls, brachyblasts or auxiblasts) of shoot meristem and shoot elongation (solid line) for GU1 (black), GU2 (red), GU3 (green) and GU4 (blue) during one annual growth
