%X Interpretation of primary growth markers (modules)
is neglected in sustainable resource management processes, yet it opens up
prospects for long time series on tree crown development, necessary for their characterization
in the current context of climate change. This study aimed to assess the morphological
variation of crown shoots in <i><span style=\"font-family:Verdana;\">Parkia biglobosa</span></i><span style=\"font-family:Verdana;\"> in the face of a changing
environment. Axis growth modules of 420 individuals of different ages were
retrospectively analyzed in the presence or absence of shading during the wet
and dry seasons in seven localities in Cote d¡¯Ivoire. The results showed that
the developmental environment of individuals did not influence the growth
modules dimensions (P &gt; 0.05). However, module size remained significantly
different between locations (P &lt; 0.05). The southern part of the gradient is
still favourable and has priority for the establishment of permanent plots. The
modules morphology differs from the youngest to the oldest individuals (P &lt;
0.05). The rainy season remains the ideal period for the implementation of
agroforestry reforestation programmes based on this species (P &lt; 0.05). </span><i><span style=\"font-family:Verdana;\">Parkia
biglobosa</span></i><span style=\"font-family:Verdana;\"> is a monochasial sympod (Pseudo-monopod) with a relay axis that
follows the Paul Champagnat architectural model in the young stage, and
transits to the Wilhelm Troll model later in the adult and old stage. This
information contributes to the understanding of the functioning of crown and
the adaptation of this species to a varying environment. It could guide choice
of suitable environment and ideal genotype for the implementation of a
reforestation or agroforestry programme based on </span><i><span style=\"font-family:Verdana;\">Parkia biglobosa</span></i><span style=\"font-family:Verdana;\">.</span>
