“…Our results showed that tree species with decreasing leaf N concentrations at 300 and 30 m showed lower LMA, suggesting possible light limitation due to canopy expansion caused by fast growth (Wu et al, 2020). Soh et al (2017) found that plants with lower LMA were replaced with plants with higher LMA during climate warming (Tang et al, 2016), due to high mesophyll conductance resistance. However, reductions in LMA may be a simple, but effective strategy, of many tree species to increase leaf cooling and acclimate to warmer temperatures.…”

Over the past 30 years, global surface temperature has increased by approximately 0.2°C per decade (IPCC, 2018). Clearly, the increase in temperature can affect tree growth and mortality (Bowman et al., 2014; Liu et al., 2016), influencing forest structure and composition in tropical forests (Zhou et al., 2013, 2014). The response of trees to warming depends on whether they can adjust their phenotypic traits; for example, many tree species maintain enhanced growth by increasing photosynthetic capacity (Drake et al., 2015). However, few studies address leaf hydraulic and economic traits, combined with related phenotypic plasticity, in long-term field warming experiments (Grady et al., 2013). Leaf hydraulic traits, such as leaf hydraulic conductance (K leaf), stomatal conductance (g s) and stomatal anatomical traits, play a vital role in regulating leaf gas exchange. K leaf measures water flow efficiency through the leaf, defining leaf water transport capacity (Locke et al., 2013). Under warmer conditions, higher K leaf may increase

Soil nitrogen (N) availability and pH are two determinants affecting plant growth, both of which are influenced by long‐term N deposition. However, the physiological mechanism of plants response to the changes in soil N availability and pH are not fully understood. To investigate the response of Picea asperata to both factors, seedlings of P. asperata were exposed to 50 or 1000 µM NH4NO3 with pH 5 or pH 7. In the current study, P. asperata, regardless of N availability and pH in growth medium, exhibited invariably a NH4 + preference. Lower root biomass, root : shoot mass ratio, total root length and area, and root vitality were detected in high N condition compared to those in low N supply, corresponding well to lower net influxes of NH4 + and NO3 - at the root surface in both pH treatments. These results indicate that P. asperata may employ an active‐forge strategy to exploit nutrient resources for growth under low N availability, probably by increased below‐ground carbon allocation and net influxes of NH4 + and NO3 - . Although low pH, to some extent may generate more malondialdehyde, P. asperata would enhance pH tolerance by increased detoxification, i.e., antioxidant enzymes (peroxidase), free proline and soluble protein as well as improved carbohydrate status (i.e., soluble sugar and starch).

The objective of this study was to reveal the regulatory mechanisms underlying the soil bacterial community of subsurface drip irrigation (SDI). The effect of different buried depths of drip tape (0, 10, 20, 30 cm) on the soil bacterial community in a tomato root-zone was investigated using high-throughput technology. Furthermore, the mutual effects of root growth, tomato yield and soil bacterial community were also analyzed to explore the response of root-soil interaction to the buried depth of drip tape. The results indicated that SDI (i.e., 10, 20 and 30 cm buried depths of drip tape) changed the soil bacterial community structure compared to surface drip irrigation (a 0 cm buried depth of drip tape). SDI with a 10 cm buried depth of drip tape significantly reduced the relative abundances of Proteobacteria, Chloroflexi, Gemmatimonadetes, Acidobacteria, Firmicutes and Planctomycetes, but significantly increased the relative abundances of Actinobacteria, Candidate_division_TM7 and Bacteroidetes. SDI of 20 and 30 cm buried depth significantly decreased the relative abundances of Roteobacteri, Actinobacteria and Planctomycetes, however, increased the relative abundances of Chloroflexi, Gemmatimonadetes, Acidobacteria, Firmicutes, Candidate_division_TM7 and especially some trace bacteria (for example Nitrospirae). Furthermore, under 20 cm or 30 cm of buried depth, the abundances of nitrogen metabolism and phosphonate and phosphinate metabolism based on the PICRUSt (Reconstruction of Unobserved States) method were significantly improved as well as soil porosity and root forks at 0-10 cm. These changes strengthened root-soil interaction and improved tomato yield per plant by 22.47% and 19.38% under 20 cm and 30 cm of buried depth, respectively, compared to surface drip irrigation. Therefore, the responses of bacterial community and root-soil interaction to drip tape buried depth of 20 cm and 30 cm are proven to be beneficial for the increasing of tomato production.
