The aim of the study was to investigate the seed and seedling anatomy, as well as to identify the reserve degradation pathway during the germination
process in Euterpe oleracea seeds. Longitudinal and transversal sections of endosperm and embryo seeds, as well as transversal sections of different
parts of the seedling were analyzed. The seeds are ruminated with the endosperm formed by cells of several sizes and forms, as well as by presenting
very large walls and pits. The embryo is formed by a hypocotyl-radicle axis, procambium and parenchyma with several idioblasts composed of
raphides. The seed endosperm has the hypocotyl base and haustorium as sites of starch accumulation. The results obtained by scanning and
transmission electron microscopy demonstrate that the endosperm cells present several pits with plasmodesma connections and the haustorium can
regulate the endosperm degradation process. Seedling sections between the endosperm and haustorium indicate that the testa projections can have the
function of transport during the degradation process of the endosperm reserves.
