“…This study focused on 11 provenances of F. hodginsii, including the local provenances within Fujian Province and the non-local provenances from other provinces. All individuals were 23-year-old mature individuals with root growth essentially stagnant; hence, the interaction between the soil and their root system also tended to be stable in this garden environment [48][49][50]. Interestingly, the exotic F. hodginsii provenances in this study (i.e., GZLP, HNDX, JXSY, and GDSX) have higher soil nutrient content (C, P, K, Ca, Mg, Fe, and Mn) than native provenances or the already widely used soil modification species in Fujian (like P. massoniana and Casuarina equisetifolia), which suggest they could be more suitable for local cultivation [51,52].…”

Aims: Fokienia hodginsii is a threatened conifer tree species, known as the dominant nursery-grown species capable of colonizing the challenging woodland environments in southern China due to its strong root penetrating ability. The ecological phenotype of Fokienia hodginsii is not well documented during its breeding process, which limits the potential planting area and its ecological function. This study aims to understand how Fokienia hodginsii associates with microbes to conduct its key ecological function and provide a theoretical basis for further improving the forest nursery management of Fokienia hodginsii. Methods: This study explored the ecological traits of 11 main Fokienia hodginsii provenances in a homogeneous garden experiment by analyzing their nutrient utilization strategies and associated microbial features in the rhizosphere soil and roots. Results: The study found that the paramount difference in the rhizosphere soil among provenances is in Ca and Fe content. Some microbial communities, namely Crenarchaeota, Verrucomicrobiota, and Desulfobacterota, were positively correlated with the amounts of the soil nutrient elements, whereas Abditibacteriota and Dependentiae were negatively correlated. The abundance of N- and Fe-related bacteria in the Fu Jian Chang Ting (FJCT) provenance was significantly higher than that in other provenances, while the C-, P-, K-, and Mg-related fungal communities, respectively, had higher abundances in the FJCT, Fu Jian Long Yan (FJLY), Fu Jian Gu Tian (FJGT), and Fu Jian Xian You (FJXY) provenances than the others. The impacts of the Gui Zhou Li Ping (GZLP), Hu Nan Dao Xian (HNDX), Jiang Xi Shang Yao (JXSY), and Guang Dong Shi Xing (GDSX) provenances on the rhizosphere soil are similar, but the differences in nutrient utilization arise from the plant itself. Conversely, the root nutrient contents of the FJCT, Fu Jian You Xi (FJYX), Fu Jian An Xi (FJAX), FJLY, Fu Jian De Hua (FJDH), FJGT, and FJXY provenances are highly correlated with soil nutrient features. Conclusions: For the native provenances, their economic traits are better than the exotic provenances. The native provenances are more sensitive to local soil conditions, so they should benefit more from human interventions, rendering them more suitable for artificial cultivation. The growth of the exotic provenances is less affected by the soil environment, making them better suited for the ecological transformation of forest stands and soil improvement.

“…The leaf δ 13 C is thus a good proxy for a long-term iWUE, especially under relatively homogenous environmental conditions. Also, as it can be easily sampled in a large number of individuals in the field while representing plant long-term trends in water-use efficiency, the leaf δ 13 C offers good insights to analyse adaptation of tree species to environmental aridity (Rabarijaona et al 2022).…”

Water-use efficiency (WUE) is affected by multiple leaf traits, including stomatal morphology. However, the impact of stomatal morphology on WUE across different ontogenetic stages of tree species is not well-documented. Here, we investigated the relationship between stomatal morphology intrinsic water-use efficiency (iWUE=A/gs) and leaf carbon isotope ratio (δ13C). We sampled 190 individuals including juvenile and mature trees belonging to 18 temperate broadleaved tree species and 9 genera. We measured guard cell length (GCL), stomatal density (SD), specific leaf area (SLA), gas-exchange, iWUE and leaf δ13C as a proxy for long-term WUE. Leaf δ13C correlated positively with iWUE for both juvenile and mature trees. Across species, GCL showed a negative and SD a positive effect on iWUE and leaf δ13C of both juvenile and mature trees. Within species, however, only GCL was significantly associated with iWUE and leaf δ13C. Pioneer species (Populus,Prunus,Betula) showed a significantly lower leaf δ13C than climax forest species (Fagus,Quercus,Tilia), but the differentiation was not clear for iWUE. We conclude that GCL and SD can be considered as functional morphological traits impacting the iWUE and leaf δ13C of trees, highlighting their potential for rapid phenotyping approaches in ecological studies.

“…They also have bigger leaf areas and leaf thickness, take deeper roots, and invest more resources in the development of belowground (fine and coarse roots) organs at the expense of aboveground (leaves and stems) ones. [15,[17][18][19][20][21][22][23][24]. This indicates their better adaptation to drought [25,26].…”

The negative impact of drought on plant growth may be modified by the different availability of mineral nutrients and by their adaptation to different local habitat conditions. In this study, we examine the impact of drought, fertilization with phosphorus and provenance, as well as their interactions, on the growth and allometric growth relationships between the belowground and aboveground organs of common beech (Fagus sylvatica L.) and sessile oak (Quercus petraea (Matt.) Liebl.). The research was conducted on saplings originating from two mature mixed stands (dry and wet provenances) dominated by these species. In the common garden experiment, saplings were exposed to regular watering and drought in interaction with moderate and high phosphorus concentrations in the growing substrate (achieved by phosphorus fertilization). The obtained results indicate the negative impact of drought and phosphorus fertilization on the growth of both species. In common beech, a negative impact of phosphorus fertilization on the adaptive capacity to drought was demonstrated by unfavorable ratios between fine root mass and the mass of other organs. The sessile oak provenances under the impact of drought showed a different root collar diameter/stem height increment ratio, which indicates their different phenotypic plasticity as a consequence of adaptation to different frequencies of dry periods in their natural habitats.
