Germination control by a hard seed coat: insights from a tropical legume.

ABSTRACT: Classifying seed dormancy is an essential task for plant propagation; however, several plant species lack information about the kind of dormancy the seeds have or inaccurate reports are passed on without an in-depth investigation. We investigated Copaifera langsdorffii, a widespread tropical species with several contrasting reports about seed dormancy in the literature, particularly on the role of their hard seed coat on germination control. The effect of aril (seed appendage related to the prevention of germination) and dormancy-break treatments on germination were evaluated. Seed coat permeability and the role of seed size and aril on imbibition have been investigated. Seed drying and storage were carried out to investigate a possible acquisition of dormancy. The influence of aril and se
