Persistence and Changes in Morphological Traits of Herbaceous Seeds Due to Burial in Soil

open access: yesAgronomy, 2020
Seeds in soil banks can survive for many years before conditions become more suitable for germination. Meanwhile, seeds undergo changes in morphology and viability. In this study, we launched an artificial seed bank experiment that included 26 species of
