“…Future research should conduct more manipulative studies to tease apart specific control factors of root exudation. In addition, Ohta et al (2019) [60] reported that the exudation rates were different among trees of different provenances. Some studies found Korean pine [61] and Larch [62] have geographical variation.…”

Research Highlights: Understanding of the spatial variation of root exudation on a regional scale can help understand the response of plant physiological activities to environmental changes. Background and Objectives: Although root exudation has become an important topic in belowground ecology, its relationship with root traits and environmental factors is poorly understood. Our objective was to explore how root traits and environmental factors influence root exudation. Materials and Methods: We used a multi-factorial design consisting of three tree species spanning across sites located at three latitudes to assess root exudation dynamics, which was measured using a syringe-basis incubation system. Results: The strongest and clearest effect observed in our study was a decrease in root exudation rates of Korean pine (Pinus koraiensis Sieb. et Zucc.) and larch (Larix gmelinii (Rupr.) Kuze.) at sites located in higher latitudes. Root exudation rates were positively related to mean annual temperature, mean annual precipitation, and negatively related to soil total organic carbon. Conclusions: Root exudation in coniferous species decreased at sites located in higher latitudes. Despite differences in root exudation rate among sites located at different latitudes and species with suitable variation in root morphological traits and environmental factors, we could not identify consistent influencing factors on root exudation rates.

“…The stand had not been managed after planting until our field survey, and the canopy was closed without any gaps. Here, we used clonal stands of the three provenances that had also been used in Ohta et al (2019): Yoshino, Yanase, and Yaku. These provenances were planted within 50 m of each other at the upper, middle, and lower parts of the slope, respectively.…”

“…Thus, this species is ideal for testing trait–growth relationships at the intraspecific level. A previous study conducted in the same common garden had shown that the root exudation rate and nutrient status of leaves and roots were higher in provenances with a high growth rate, indicating that adaptive divergence in nutrient‐uptake strategies among provenances causes a difference in growth rates (Ohta et al, 2019). Based on this, we tested the prediction that provenances in which leaf and whole‐tree traits are associated with high NAR (e.g., high photosynthetic rate, conductive tracheid, and high nitrogen content) and high LAR (e.g., low LMA, low wood density, and high fraction of leaf mass) show high RGR in terms of height and diameter.…”

To elucidate the physiological and morphological factors underlying intraspecific variation in growth rate, we examined the variation in leaf and whole-tree traits for three geographical variations of ca. 45-year-old Japanese cedar (Cryptomeria japonica D. Don) with contrasting heights and radial growth in a common garden. Traits that reflect leaf-level photosynthesis, water relations, and whole-tree level crown structure in relation to light use and hydraulic architecture were measured. Overall, intraspecific variation in growth characteristics in field-grown adult trees was regulated by whole-tree properties rather than leaf properties. Most leaf traits were similar among provenances. Nevertheless, the leaf traits exhibited highest maximum net photosynthetic rate, dark respiration rate, and light compensation point in provenances whose native habitats are most similar to the common garden in the present study. Together with previous reports that this provenance has higher root nutrient acquisition capacity than the other two provenances, it can be said that organ-level resource use strategies are coupled in a tandem manner. At the whole-tree level, hydraulic architecture-as explained by axial variation in the hydraulically weighted tracheid diameter-can be linked to leaf distribution with respect to light use strategies as well as water transport capacity, leading to differences in growth characteristics among provenances. The study of intraspecific variation in growth characteristics in trees with a wide range of native habitats is expected to be a useful indicator for predicting changes in growth potential and forest dynamics in response to climate change in each habitat.

“…This finding indicates that the different strategies of BVOC emission would be favored under different environments together with other carbon allocations, such as growth 26 and root exudation 27 . The defense-growth trade-off might be a driver of the geographic variation of traits 28 in C. japonica , but diversification of strategies for water and nutrient utilization should be another driver in heterogeneous geology and climate where water and nutrient availabilities are much different among the locations of the populations 27 . During the last glacial period, the distributions of fungi inhabiting Japanese cedar may have been geographically structured, although they would have also been inhabiting other hosts.…”

Biogenic volatile organic compounds emitted from plants are important constituents of atmospheric chemistry and play a major role in the resistance of plants against various environmental stresses. However, little is known about how abiotic and biotic environments on a geographic scale relate to diversifications of the emission. Here, we present variations of terpenes stored in and emitted from leaves of a single species in a common garden, using genetically differentiated local populations of Japanese cedar, the most dominant and widely distributed tree species in Japan. Furthermore, we determined the composition of fungal communities in 50 locations, based on the presence or absence of 158 fungal species inhabiting the cedar. The results showed that terpenoids, especially those that are emitted, were highly diversified and geographically structured among the 12 populations. The total amount of stored terpenes was negatively affected by warm and less-snow climates. On the other hand, variations in some emitted terpenoid species among the populations were correlated to antagonistic fungal species inhabiting the Japanese cedar. We propose that the diversification of composition and amount of stored and emitted terpenoids in the tree species is not only structured by climate, but also antagonistic fungal communities through biological interactions.
