A greater cavitation resistance, a greater cellular dehydration resistance?
Résumé
Hydraulic failure, characterized as tree's inability to transport water to its living cells, has been identified as the key factor triggering a cascade of physiological processes leading to increased cell mortality. As leaves are the headquarters of photosynthetic processes and gas exchanges, maintaining them alive seems crucial for trees growth and survival. Thus, it is now imperative to determine whether a greater cavitation resistance at the leaf level correlates with a greater resistance to cell mortality to identify the species that could help maintaining our forest ecosystems.
