Do variations in dormancy and germination across achenes from peripheral, intermediate and central positions contribute to the success of the cold desert annual Heteracia szovitsii?
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...
Substantial evidence supports morpho-physiological dormancy (MPD) as the basal kind of seed dormancy in flowering plants. However, for seeds of waterlilies (Nymphaea, Nymphaeaceae), only physiological dormancy (PD) is...
Germination of species with hard woody indehiscent endocarps has troubled seed scientists for many years. To understand how germination is regulated in such species Chia et al. show that the conditions required for...
The contribution of variation in seed bank dynamics to local adaptation is not well studied. Postma et al. investigated the extent to which genetic and environmental factors affect dormancy cycling and mortality of...
Thermal thresholds for seed dormancy release and germination are important tools for predicting germination timing. Orrù et al. study germination in seeds of Vitis vinifera subsp. sylvestris collected from four...
Seeds from different populations of the same species often show distinct germination responses to the smoke-derived chemical karrikinolide (KAR1), thus limiting its potential for use in weed management. Gorecki et al...
Karrikinolide (KAR1) is a smoke-derived chemical that can trigger seeds to germinate, and shows promise as a tool for flushing out weed seeds from the soil seed bank. Long et al. demonstrate that weeds of Brassicaceae...
