Key message No soil nutrient differences between two plantations. In contrast to NSC, N and P concentrations were greater in black locust than in Chinese pine. NSC negatively, N and P positively related to precipitation for both plantations. Abstract Precipitation is a key environmental factor affecting carbon (C), nitrogen (N), and phosphorus (P) status of plants and soils, especially in water-limited...
Key message C:N remained constant, but C:P and N:P were higher in the 37-year-old stands. The correlations were linked by P and N:P among plant, but N:P and C:P between soil and plant. Abstract Carbon (C), nitrogen (N), and phosphorus (P) stoichiometries are critical indicators of interlinked biogeochemical cycles in terrestrial ecosystems. However, the linking manner between plant and soil in plantations...
Key messagePrince Rupprecht’s Larch from the Loess Plateau takes up and assimilates a greater proportion of N as NO3−, particularly at neutral pH, whereas Chinese Fir assimilates a greater proportion of N as NH4+...
Key messageOnly severe drought stress induced lower non-structural carbohydrate concentrations inRobinia pseudoacaciasaplings, and non-structural carbohydrate reduction occurs solely in branches and stems at the end of the growing season. Abstract A better understanding of non-structural carbohydrate (NSC) dynamics in trees under drought stress is critical to elucidate the mechanisms underlying...
