“…The finding that N supply significantly increased the soil N element availability (STN, SNH, SNO, SAP) of both P. tabuliformis and F. chinensis, and thus improved the LNC and RNC of the target trees, is consistent with our previous study [15]. With the improvement of soil N availability, plants with a higher LNC tended to possess greater capacities for foliar N uptake and storage, which promoted leaf photosynthesis and tree biomass accumulation [34,42]. Meanwhile, RNC was considered a vital predictor of root nutrient and respiration, and roots with high N contents could increase the metabolic activity and root nutrient uptake rates [18].…”

“…N affected both the aboveground and belowground functional traits of P. tabuliformis. Under N fertilization, the tree height and SLA of P. tabuliformis tended to be higher, indicating that the coniferous tree could improve the capacity to capture light energy and promote leaf photosynthetic efficiency [34]. Thus, P. tabuliformis might adapt to the high N deposition environment and increase the aboveground biomass mainly through increasing the aboveground acquisitive traits.…”

Nitrogen (N) is one of the limiting nutrients for plant growth and metabolism in terrestrial ecosystems. Numerous studies have explored the effects of N addition on the eco-physiological traits and biomass production of plants, but the underlying mechanism of how N deposition influences biomass allocation patterns remains controversial, especially for urban greening trees. A greenhouse experiment was conducted for 7 months, using two dominant tree species of urban streets in North China, including the coniferous tree species Pinus tabuliformis and the broadleaved tree Fraxinus chinensis, under three levels of N addition: ambient, low N addition, and high N addition (0, 3.5, and 10.5 gN m−2 year−1). The plant growth, biomass distribution, functional traits, and soil nutrient properties of the two trees were determined. Overall, N addition had positive effects on the aboveground and belowground biomass of P. tabuliformis, which also shifted its functional traits to an acquisitive strategy, while F. chinensis only increased root biomass distribution and fast traits as N increased. Furthermore, N supply increased the soil N and phosphorus availability of both trees and improved their root nutrient uptake capacity, resulting in an increase in their root–shoot ratio. Optimal partitioning theory could better explain why trees would invest more resources in roots, changing root structure and nutrient uptake, thus increasing root biomass allocation to adapt to a resource-poor environment. These findings highlight the importance of plant functional traits in driving the responses of biomass allocation to environmental changes for urban greening dominant tree species and could help to come up with new tree growth strategies in silvicultural practice for urban green space.
