“…This result strongly suggested that a significant amount of leaf N in Chinese sea-buckthorn derives from SNF, especially in the warmer habitats at lower altitudes. Root nodules of sea-buckthorn have strong N-fixing ability and can fix 180 kg N ha À1 year À1 , twice the amount reported for soybean nodules (Akkermans 1971;Oremus 1979). Plant N-fixation is affected markedly by soil temperatures (Sprent 1979;Reddell et al 1985;Danso et al 1992), as would be expected for Chinese sea-buckthorn.…”

Nitrogen (N) and phosphorus (P) concentrations and N:P ratios in terrestrial plants and their patterns of change along environmental gradients are important traits for plant adaptation to changes. We determined the leaf N and P concentrations of Chinese sea‐buckthorn (Hippophae rhamnoides L. subsp. sinensis Rousi), a non‐legume species with symbiotic N fixation (SNF), at 37 sites across northern China and explored their geographical patterns in relation to climate and soil factors. (1) The mean leaf N, P, and N:P ratio were 36.5, 2.1 mg g−1, and 17.6, respectively, higher than the mean values of most shrub species in the region. (2) Leaf N was correlated with soil mineral N in cool areas (mean annual temperature MAT <3 °C) but with temperature in warm areas (MAT >3 °C). The high leaf N and divergent leaf N–soil N relationship suggested the importance of SNF in plant N uptake; SNF increases with temperature and is probably the major N source in warm areas. (3) Leaf P was positively related to mean annual precipitation. Leaf N:P ratio was primarily driven by changes in leaf P. The high leaf P reflected the greater requirements of the N‐fixing species for P. Our results represent a major advance in understanding the elemental stoichiometry of non‐legume N‐fixing plants, indicating high P and N requirements and a shift in N source from SNF to soil as temperature declines. This knowledge will help in assessing the habitat suitability for the species and predicting the species dynamics under environmental changes.

“…Sea buckthorn ( Hippophae rhamnoides L.), as a typical shrubby reforestation plant used as the desertification control project of China, has physiological and morphological traits that allow it to grow under conditions of frequent aridity and salinity (Li & Schroeder, ; Li, Xu, Zang, Korpelainen, & Berninger, ; Wu, Li, Li, et al, ). It is native to Europe and Asia and is naturally distributed on river banks and costal dunes (Oremus, ; Richards & Burningham, ). Natural stands and plantations of this shrub characterize forest stand structures, with canopy coverage exceeding 55% and reaching a height of more than 2 m (Isermann, Diekmann, & Heemann, ; Li & Schroeder, ).…”

Sea buckthorn (Hippophae rhamnoides L.) plantations play crucial roles in the prevention of soil erosion and control of desertification on the Qinghai–Tibetan Plateau; however, the limited information on the age‐related water uptake patterns of H. rhamnoides and their relationships with associated grasses species weakens our understanding of how these factors influence the management of H. rhamnoides plantations. Therefore, this study investigated the seasonal variations in water uptake patterns of different‐aged H. rhamnoides and their associated species via stable isotopes and leaf water potential analyses. The model results showed that seedling (Hs) and juvenile (Hj) H. rhamnoides extracted water mainly from shallow and middle soil layers throughout the growing seasons, whereas mature H. rhamnoides (Hm) exhibited high plasticity, shifting water source between shallow soil water and groundwater when the former become less available. By contrast, the associated grasses (Taraxacum mongolicum, Thermopsis lanceolata, and Polygonum sibiricum) mainly absorbed shallow soil water across the whole growing seasons, suggesting that direct competition for shallow soil water occurred between grasses and H. rhamnoides. In addition, the obviously higher δ13C values of Hj with more negative predawn (mean Ψpd, −1.37 MPa) and midday (mean Ψmd, −2.23 MPa) leaf water potential indicated the Hj experienced greater water stress relative to Hs and Hm. These results provide new understanding of the seasonal water use strategies of different‐aged H. rhamnoides, which will be important for the successful management of plantations in this region.
