“…As expected, compared with the control condition, P n , C i and T r of all saplings decreased significantly in response to wind erosion (Table 2). The gas exchange reduction caused by wind erosion has been reported previously, such as Calligonum mongolicum (Fan et al, 2018), Rhododendron ferrugineum (Caldwell, 1970), and Averrhoa carambola (Marler and Zozor, 1992). We found that females always exhibited greater P n than did males under either control or wind erosion.…”

“…Previous studies have reported that morphological growth and biomass accumulation of plants are significantly inhibited under wind erosion environment (Yu et al, 2008;Li et al, 2010;Liu et al, 2014a). Photosynthesis, including net photosynthetic rate and chlorophyll fluorescence parameters, also shows similar trends (Fan et al, 2018). Adjustments in morphological and physiological characteristics constitute the important means by which plants increase their resistance and adaptability (Anten et al, 2005;Liao et al, 2020).…”

“…Aeolian environment is regarded as one of the extreme environments that seriously affect plant growth and reproduction in the dune ecosystem of arid and semi-arid areas ( Shi et al., 2004 ; Dech and Maun, 2006 ; Perumal and Maun, 2006 ; Gilbert and Ripley, 2010 ; Tang et al., 2016 ; Fan et al., 2018 ). Affected by windblown sand movement, plants growing on the leeward slopes of dunes often suffer partial or complete sand burial, whereas those on the windward slopes of dunes experience varying degrees of wind erosion ( Luo and Zhao, 2015 ; Luo et al., 2018 ).…”

Effects of wind erosion on growth and adaptability have been widely reported in many plants, but little attention has been paid to dioecious plants. Recent studies have shown that sex-specific responses to environmental changes in many plants exist. To explore sexual differences in response to wind erosion, female and male Salix gordejevii saplings growing on inter-dune land (no erosion) and on the windward slope of the dune (20cm wind erosion) in Hunshandake Sandy Land were chosen and their morphology, biomass and physiological traits were investigated, respectively. Wind erosion significantly reduced plant growth, biomass accumulation, gas exchange and chlorophyll fluorescence, and obviously disrupted osmotic regulation function and antioxidant enzyme system in both sexes, especially in males. Under wind erosion condition, females exhibited higher sapling height (SH), basal diameter (BD), leaf dry mass (LDM), root dry mass (RDM), total dry mass (TDM), root percentage in total dry mass, net photosynthesis rate (Pn), maximum efficiency of photosystem II (Fv/Fm), effective quantum yield of PSII (ΦPSII), relative water content (RWC) of leaves, superoxide dismutase (SOD) and peroxidase (POD) activities, but lower malondialdehyde (MDA), proline as well as soluble sugar content than did males. However, no significant sexual differences in most of these traits were observed under no erosion condition. Our results demonstrated that females possess a greater resistance to wind erosion than do males, with females having a better photosynthetic capacity, stronger water retention capacity and more efficient antioxidant system to alleviate negative effects caused by aeolian environment.

Involvement of soluble proteins in growth and metabolic adjustments of drought‐stressed Calligonum mongolicum seedlings under nitrogen addition

The planting of seedlings is the most effective measure for vegetation restoration. However, this practice is challenging in desert ecosystems where water and nutrients are scarce. Calligonum mongolicum is a sand-fixing pioneer shrub species, and its adaptive strategy for nitrogen (N) deposition and drought is poorly understood. • Thus, in a pot experiment, we studied the impacts of four N levels (0, 3, 6, 9 gNÁm −2-Áyear −1) under drought or a well-watered regime on multiple eco-physiological responses of 1-year-old C. mongolicum seedlings. • Compared to well-watered conditions, drought considerably influenced seedling growth by impairing photosynthesis, osmolyte accumulation and activity of superoxide dismutase and enzymes related to N metabolism. Nitrogen addition improved the productivity of drought-stressed seedlings, as revealed by increased water use efficiency, enhanced superoxide dismutase and nitrite reductase activity and elevated N and phosphorus (P) levels in seedlings. Nevertheless, the addition of moderate to high levels of N (6-9 gNÁm −2 Áyear −1) impaired net photosynthesis, osmolyte accumulation and nitrate reductase activity. N addition and water regimes did not markedly change the N:P ratios of aboveground parts; while more biomass and nutrients were allocated to fine roots to assimilate the insufficient resources. Soluble protein in assimilating shoots might play a vital role in adaptation to the desert environment. • The response of C. mongolicum seedlings to N addtion and drought involved an interdependency between soluble protein and morphological, physiological and biochemical processes. These findings provide an important reference for vegetation restoration in arid lands under global change.

Background: Sand burial plays an irreplaceable and unique role in the growth and distribution of vegetation on the Shell Dike Island in the Yellow River Delta. There are still some unknown on the effects of sand burial on the morphology, biomass, and especially the stoichiometry of Periploca sepium, as well as the relationship between these factors. Results: Shell sand burial depth had a significant influence on seedling emergence, growth, and biomass of P. sepium. Shallow sand burial shortened the emergence time and improved the emergence rate, morphological and biomass of P. sepium compared to deep burial and the control. Burial depth significantly affected the nitrogen (N) and phosphorus (P) contents of the leaves. With deep burial, the carbon/nitrogen (C/N) and carbon/phosphorus (C/P) ratios decreased firstly and then increased with depth, while the nitrogen/phosphorus ratio (N/P) presented the contrary trend. Correlation analysis showed that the stoichiometry of N/P was positively correlated to morphology and biomass of P. sepium at different burial depths. Structural equation model analysis revealed that N was the largest contributor to P. sepium biomass. Conclusions: Optimal burial depth is beneficial to the seedling emergence, growth and nutritional accumulation of P. sepium. Stoichiometry has an important influence on the morphological formation and biomass accumulation.
