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?
In sea beet, Beta vulgaris ssp. maritima, seed dormancy largely controls germination timing, is highly heritable and varies geographically; climate might select for this trait. Wagmann et al.Β assess geographical...
Several ecologically important plant families in Mediterranean biomes have seeds with morphophysiological dormancy. Hidayati et al.Β study four species of the intractably dormant Australian genus Hibbertia (Dilleniaceae)...
