Ecophysiology of Seed Dormancy in the Australian Endemic Species Acanthocarpus preissii (Dasypogonaceae)

• Background and Aims Seedlings of Acanthocarpus preissii are needed for coastal sand dune restoration in Western Australia. However, seeds of this Western Australian endemic have proven to be very difficult to germinate. The aims of this study were to define a dormancy-breaking protocol, identify time of suitable conditions for dormancy-break in the field and classify the type of seed dormancy in this species.
