Background And Aims: Little is known about environmental factors that break morphophysiological dormancy in seeds of the Annonaceae and the mechanisms involved. The aim of this study was to characterize the morphological and physiological components of dormancy of Annona crassiflora, a tree species native to the Cerrado of Brazil, in an ecophysiological context.
Methods: Morphological and biochemical characteristics of both embryo and endosperm were monitored during dormancy break and germination at field conditions.
