Germination Characteristics Is More Associated With Phylogeny-Related Traits of Species in a Salinized Grassland of Northeastern China

Knowing the determinants of seed germination helps us understand plant adaptive strategies to environment and predict population community regeneration under climate change. However, multiple factors, including traits that influence their relative importance, have received little attention. Here, experiments were conducted on newly collected seeds for 89 herbaceous species from salinized Songnen grassland. We tested effects phylogeny-related morphological physiological percentage initial time contribution shaping variation. found biennials had higher percentages rates than annuals perennials. Species with brown those yellow black seeds. Eudicots germinated faster monocots, morphophysiological dormancy required more initiate other kinds dormancy. Phylogeny-related factors explained variation in traits. Seed mass volume large-seeded, but not small-seeded group positively correlated percentage. Our findings provide important information understanding across local adaptation
