Despite increasing efforts towards habitat and species protection in Europe since the 1990s, when the Fauna-Flora-Habitat directive was adopted, the proportion of threatened plant species has steadily increased. One...
Water-impermeable seeds have structures (βwater gapsβ or lens in legumes) for detecting environmental cues that cause them to become water-permeable (nondormant). Physical dormancy is common in legume species, whose...
A water-impermeable testa may act as a barrier to seed imbibition, imposing dormancy. JanskΓ‘ et al. test six pea accessions of contrasting dormancy type for their ability to imbibe. The strophiole is identified as the...
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 <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...
