“…High LMA is an indicator of conservative ecological strategy and is a general feature of leaves from unproductive or stressful environments (Reich, Walters, & Ellsworth, ; Wright et al., ). Accordingly, high LMA is favoured in areas with frequent or severe frost (González‐Zurdo et al., ; Mediavilla, González‐Zurdo, Babiano, & Escudero, ; Ogaya & Peñuelas, ).…”

Occupancy of cold habitats by evergreen species requires structural modification of photosynthetic organs for stress resistance and longevity. Such modifications have been described at interspecific level, while intraspecific variation has been underexplored. To identify structural and anatomical traits that may be adaptive in cold environments, we studied intraspecific variability of needles of Scots pine (Pinus sylvestris L.), a wide‐ranging tree, along a 1,900 km temperate–boreal transect in Europe. Needles from 20 sites representing mean minimum winter temperatures between −4.0 and −19.9°C and mean annual temperatures between 8.3 and −1.7°C were sampled for measurements of leaf mass per area (LMA, g/m2), leaf density (LD, g/cm3) and 30 other morpho‐anatomical traits. Needles from cold sites lived longer, were shorter, showed higher LMA and LD, had narrower and more collapse‐resistant tracheids, thicker epidermal cells with thicker cell walls and wider resin ducts occupying larger fraction of needle volume in comparison to needles from warmer sites. Along the steep climatic gradient, needles presented a coordinated phenotypic spectrum of external and internal traits that are largely interpretable in functional, adaptive terms. This intraspecific pattern of covarying traits provides insight into the adaptive syndrome associated with stress tolerance and extended needle longevity under cold conditions of high latitudes.

“…At low temperatures, More N is allocated to the light-harvesting complex to absorb more light energy for photosynthesis. At high temperatures, previous studies have suggested that more N should be invested in the RuBP carboxylase process to optimize the photosynthesis efficiency [54][55][56][57]. Thus, the response of J/V ratio to leaf temperature is parabolic, with a peak at an optimum temperature in subtropical evergreen plantation ( Figure 5).…”

“…The seasonal variation in the J/V ratio is due to the difference in the partitioning of leaf nitrogen between different fractional pools [53]. This partitioning involves the distribution of leaf nitrogen between the Rubisco and light-harvesting fractions [54][55][56]. At low temperatures, More N is allocated to the light-harvesting complex to absorb more light energy for photosynthesis.…”

Photosynthesis is arguably the most important biochemical process on Earth, which is dramatically influenced by environmental conditions. How environmental factors drive stomatal conductance and biochemical processes of leaf photosynthetic rate has not been sufficiently investigated in subtropical China. In this study, we analysed the effects of stomatal and biochemical parameters on the photosynthetic rate of native Masson’s pine (Pinus massoniana Lamb.) and exotic slash pine (Pinus elliottii Engelm.) in response to leaf temperature and vapour pressure deficit (VPD) in subtropical China, based on leaf gas exchange measurements in 2016. Our results showed that there was no significant difference in the light-saturated photosynthetic rate (Asat) between native Masson’s pine and exotic slash pine. The seasonal patterns of maximum rate of the carboxylation (Vcmax25) were basically consistent with seasonal patterns of Asat for both species. The positive effect of leaf temperature on Asat was mainly produced through its positive effect on Vcmax25. Leaf temperature had no significant effect on stomatal conductance. Vcmax25 and gs simultaneously affected Asat in response to VPD. Our results highlighted the importance of biochemical processes in limiting leaf photosynthetic rate in response to environmental conditions in subtropical evergreen coniferous plantations.
