Fire and germination in a tropical savanna
Are seeds using heat from fires as a signal to end physical dormancy and germinate?

Function of the pleurogram
Water-impermeable seeds have structures (“water gaps” or lens in legumes) for detecting environmental cues that cause them to become water-permeable (nondormant). Physical dormancy is common in legume species, whose...
Pea seed testa and its role during the establishment of physical dormancy
A water-impermeable testa may act as a barrier to seed imbibition, imposing dormancy. Janská et al. test six pea accessions of contrasting dormancy type for their ability to imbibe. The strophiole is identified as the...
Sand temperature and moisture break seed physical dormancy
Seasonal periodicity of seed germination and its relationship to seasonal changes in temperature and soil moisture have been well studied in seeds of species with physiological dormancy. However, relatively little...

Physical dormancy and the water gap in Geranium
Physical dormancy and the water gap in <i>Geranium</i> A water gap is a small opening that forms on breaking of dormancy in physically dormant seeds or fruits. Gama-Arachchige et al. examine the development...
