Sex-specific responses to winter flooding, spring waterlogging and post-flooding recovery in Populus deltoides

Abstract Winter flooding events are common in some rivers and streams due to dam constructions, and flooding and waterlogging inhibit the growth of trees in riparian zones. This study investigated sex-specific morphological, physiological and ultrastructural responses to various durations of winter...
