A new study published in Current Forestry Reports, the result of a collaboration between CNR-IRET, the University of Québec, Northern Arizona University, the Slovenian Forestry Institute, and WSL, synthesizes recent advancements and identifies knowledge gaps in the phenology of both belowground and aboveground organ development in extra-tropical forest ecosystems.
Phenology, the study of periodic life cycle events in plants, is essential for understanding tree health, resource competition, and the impact of climate change on ecosystems. By examining the phenological processes of various organs, the study aims to provide a comprehensive understanding of how these processes are interconnected and how they influence ecosystem dynamics. The article highlights the importance of integrating ecophysiological knowledge into phenological research.
Leaf phenology would benefit from more studies focusing on autumn events. Indeed, compared to the beginning of the growing season, much less is known about its end, despite its significance in understanding processes such as carbon uptake and nutrient cycling. Advancing knowledge on cambial phenology and wood formation will require greater attention to angiosperms, as research on xylogenesis has historically focused on gymnosperms.
Similarly, an in-depth exploration of phloem phenology is essential for better understanding the links between phenological processes in different organs. Finally, the study highlights that the phenology of both fine and woody roots remains less explored than that of other organs and emphasizes the need for more extensive research on these structures.
