Are winter and summer dormancy symmetrical seasonal adaptive strategies?
Dormancy in higher plants is an adaptive response enabling plant survival during the harshest seasons and has been more explored in woody species than in herbaceous species. Nevertheless, winter and summer shoot meristem dormancy are adaptive strategies that could play a major role in enhancing seasonal stress tolerance and resilience of widespread herbaceous plant communities.
This review article highlights research priorities such as the identification of seasonal factor thresholds and the analysis of biochemical compounds implicated in the dormancy modes of induction and release. Gilliespie and Volaire provide an overview of the growth-stress survival trade-offs inherent in summer and winter dormancy which reinforces the existing body of research on plant adaptations to extreme conditions under climate change.
