After its application, the systemic fungicide penetrates into the plant and migrates acropetally
even into the parts of the plant not reached by the application (Stubler et al.
In Myriophyllum spicatum the inflorescence is a cylindrical spike raised on an elongated peduncle with acropetally
arranged unisexual flowers.
It translocates both acropetally
and basipetally to the roots or by leaves.
In this context, Sell (1980) suggested that the enrichment axes flower basipetally while the inflorescence branches develop acropetally
As apparent from the Figures, the total number of central and peripheral vascular bundles declined acropetally
from the peduncle to the rachis till it attained minimum values of 4 and 12 respectively at the internode below the terminal spikelet.
Internode lengths increased acropetally
for both cultivars, with the steepest increase between the second and apical phytomers.
Thus, its enrichment zone is made up of paracladia which repeat the acropetally
following synfiorescence (Fig.
Photosynthate may travel acropetally
from parent to offspring, but not in reverse (similar to a previous model of translocation; Caraco and Kelly 1991).
