| 英文摘要 | Compared to evergreens, deciduous tree species need to achieve a complete vegetative and reproductive growth cycle over the course of their shorter growing season each year. However, the cell-level anatomical and physiological mechanisms underlying the higher photosynthetic capacity in deciduous group than in evergreen group are not well known. Ten deciduous and ten evergreen angiosperm tree species from a subtropical common garden were compared in terms of cell-level anatomical and physiological traits related to photosynthesis. After phylogeny was considered by phylogenetic independent contrast analysis, the higher light-saturated area-based photosynthesis (AN) in deciduous species was evolutionally associated with increased stomatal conductance and mesophyll conductance. The difference in mesophyll conductance between evergreen and deciduous groups was mainly determined by mesophyll and chloroplast surface area exposed to intercellular air space rather than other anatomical traits. Furthermore, deciduous group displayed a faster induction speed of AN than evergreen group, mainly caused by the maintenance of higher stomatal conductance in deciduous group. Therefore, deciduous tree species generally had higher AN under both constant high light and fluctuating light. These photosynthetic physiology and anatomical traits at cell level allowed deciduous trees to fulfil carbon gains comparable to evergreen species despite their shorter growing season. |
