“…Tree after long-term growth in different ecological environments undergo adaptive geographic variation to the local habitat, forming different geographic provenances [ 32 ]. However, each species has a certain range of adaptation to the environment, and the variation of functional traits has a certain limit too [ 33 ]. The results from the present study demonstrate high intraspecific variability in leaf traits among provenances and individual trees within provenances.…”

Background Studies on intra-specific variability in leaf functional traits is important to evaluate adaptation of the species to predicted climate change, and to develop long-term conservation strategy. The main objectives were to investigate the relationship between the functional traits leaves and C, N, P stoichiometry of Chinese fir from different geographical provenances and their relationship with the main environmental factors of provenance. Results In this study, we measured 12 leaf functional traits on 36-year-old Cunninghamia lanceolata trees from 13 provenances. Analysis of variance (ANOVA) was performed to examine the variability. Redundancy analysis (RA) was computed to examine the relationship between geo-climatic factors of provenance origin and leaf functional traits while Pearson’s correlation coefficient was computed to assess inter-trait correlations. The results showed statistically significant differences (P < 0.01) in intraspecific leaf traits among provenances, except leaf P content. The relationships among leaf traits are consistent with the general trend observed in the leaf economic spectrum. Mean annual temperature appeared to be a key factor that influences intraspecific leaf traits variability compared to mean annual precipitation. Conclusion These results provide useful insights about adaptation of leaf trait of Chinese fir in a changing climatic condition. Thus, our findings shed light on the importance of interspecific trait variability in Chinese fir and the potential effect of climate change.

“…Plant species can respond to environmental variations through intraspecific leaf trait plasticity. For example, the leaf traits of Pinus tabuliformis vary at the regional scale (Zhang et al 2017). Therefore, a large species distribution range may lead to large intraspecific variation in leaf traits (Albert et al 2011, Siefert et al 2015.…”

Understanding the relationships among leaf and size traits and environment factors is essential for understanding and predicting the dynamics and ecophysiological processes of moso bamboo (Phyllostachys edulis) forests across their distribution range. Here, we evaluated these relationships at six sites within the moso bamboo distribution area in China. Specifically, we collected climate (mean annual temperature and precipitation) and soil physicochemical data from the sites, and we measured 14 leaf traits and 2 size traits (height and diameter) of both new and old moso bamboos and evaluated the relationship among environment factors, size traits and leaf traits. Climate factors had significant effects on the leaf traits of new bamboos but on those of old bamboos. For instance, mean annual precipitation (MAP) was the main driver of leaf-trait variation in new bamboos but not in old bamboos. Specifically, MAP was significantly negatively correlated with leaf mass (LM), leaf dry matter content, single leaf area (LA), and leaf width, but positively correlated with specific leaf area and the leaf length to width ratio. Moreover, potential evapotranspiration and solar radiation (SR) significantly affected the leaf nutrient traits of new bamboos. Mean annual temperature and actual evapotranspiration were significantly positively correlated with bamboo height. Bamboo diameter at breast height (DBH) had more explanatory power with respect to leaf traits than plant height, and LA, leaf length and width, and LM all decreased with increasing DBH in new bamboos. A structural equation model showed that soil physicochemical traits significantly affected leaf traits, but not size traits, of new bamboos. Overall, our study indicated an age-dependent response of bamboo leaf traits to environmental factors, although bamboos do not have secondary growth. These results suggest that future environmental changes, including climate change, will lead to age-related responses of bamboo leaf traits, which may further result in changes in stand structure and productivity of moso bamboo forests.
