Fig. 5From: Dating branch growth units in a tropical tree using morphological and anatomical markers: the case of Parkia velutina Benoist (Mimosoïdeae) a–e Modalities of longitudinal growth observed in branches sampled in P. velutina. Schemes show growing axes and grey symbols are leaves borne by SGU. The symbol “=” indicates that a new SGU is formed after leaf shedding on the previous SGU, whereas symbol “─” indicates that a new SGU is formed without leaf shedding on the previous SGU. Sequences a, b and c take place over approximately 1 year, whereas sequences d and e take place over several years (here ca. 3 years)Back to article page
