“…(Marshall 1985;Pallardy 2008a, b). Our results agree with previous research where decreasing growth-limiting factors reduced the concentration of soluble NSC to use that carbon for structural growth (Peng et al 2021;Chen et al 2022). On the other hand, while treatments with growth restrictions showed a higher concentration of soluble NSC (mg glucose per 100g of fresh weight), treatments without growth restrictions showed almost three times more biomass, leading to a higher total content of soluble NSC (total mg of glucose per seedling) (Tables 3 and 5).…”

“Sangre de Drago” (Croton urucurana Baill.) is a native tree of South America with high value for urban afforestation or the restoration of riparian forests. This study aimed to evaluate the effect of container size and fertilization on the quality of seedlings produced in a plug+1 system. In the establishment phase, the impact of container size (110 mL or 250 mL) and fertilization (with or without) on seedling quality were evaluated before transplanting into bigger containers. In the rapid growth phase, the effect of container size (1 L, 1.5 L, and 3.5 L) on survival and seedling quality was evaluated. At the end of each phase, seedling quality was evaluated through morphological and physiological attributes. Data were analyzed through linear models, generalized linear models, and nonlinear regressions. In the establishment phase, seedlings grown in 250 mL containers with fertilization showed the best performance in morphological and physiological variables and the Dickson quality index. In the rapid growth phase, seedlings grown in 3.5 L containers showed the highest values in total height, stem diameter, total dry weight, Dickson quality index, and the lowest mortality at the end of the experiment. We recommended 250 mL containers with fertilization in the establishment phase until the seedling can be lifted with its intact root ball. We then transplant it into 3.5 L containers for the rapid growth and hardening phases until out-planting.

“…NSCs are the products of photosynthesis and provide energy for plant growth and metabolism, playing an important role in plant responses to environmental changes 32 . Some studies have reported that N addition increased NSC accumulation 31 , but other studies found that N addition had no effect on or even decreased NSC concentrations 4 , 9 . In this study, we found that NSC concentrations of different organs of R. soongorica significantly increased with mild to moderate N addition (0–9.2 g N m −2 year −1 ), but slightly decreased under the highest N addition treatment (13.8 g N m −2 year −1 ).…”

“…For example, drought either significantly increased or maintained total NSC concentrations in aboveground plant organs, but reduced total NSC concentrations in sapling roots 8 . N and P fertilization greatly reduced leaf, stem, and root NSC concentrations in Moringa oleifera seedlings, possibly because of the dilution effects of increased biomass following fertilization 9 . Thus NSCs and their components (soluble sugar and starch) display different responses to different environmental factors among different organs 10 , 11 .…”

Reaumuria soongorica is an important biological barrier for ecological protection in the Gobi Desert in northwestern China, where soil nitrogen availability is low. N deposition has recently increased significantly in Gobi Desert, and the responses of R. soongorica to N enrichment may become a problem for ecological restoration and protection. However, little is known about the effects of N addition on the biomass, non-structural carbohydrates (NSC), and carbon:nitrogen:phosphorus (C:N:P) stoichiometry of R. soongorica in this region. Here, we examined changes in biomass, NSC and C:N:P ratios of different organs of R. soongorica seedlings in four N addition treatments: 0 (N0), 4.6 (N1), 9.2 (N2), and 13.8 (N3) g m−2 year−1. N addition up to 9.2 g m−2 year−1 significantly increased the biomass of different organs, simultaneously increasing the belowground: aboveground ratio of R. soongorica seedlings. Root NSC concentrations significantly increased under all N addition treatments, but leaf and stem NSC concentrations only increased under the N1 and N2 addition treatments. Nitrogen addition enhanced the soluble sugar concentrations (SSC) of leaves and roots, and reduced starch concentrations (SC) of all organs. Stem and root N concentrations significantly increased under the N2 and N3 treatments, and leaf N concentrations only increased under the N3 treatment, but N addition had no significant effect on plant C and P concentrations. Leaf and stem C:N ratios decreased significantly under the N2 and N3 treatments, but root C:N decreased significantly in all N addition treatments. The N3 treatment significantly increased the N:P ratio of all organs. N addition significantly enhanced available N (AN), available P (AP) and total phosphorus (TP) in rhizosphere soil. Our results suggest that N addition alters the biomass, NSC, N concentrations, C:N and N:P ratios of all plant organs, but roots responded more strongly than stems or leaves to N addition, potentially allowing the plants to absorb more water from the arid soil in this region ensuring the survival of R. soongorica seedlings. Rhizosphere soil AP, AN and TP concentrations were important factors affecting the NSC concentrations and stoichiometric characteristics of R. soongorica.

“…NSC is the product of photosynthesis and provide energy for plant growth and metabolism, meanwhile it play an important role in the response of plants to environmental changes 31 . Some studies reported that N addition increased the NSC accumulation 30 , but other studies found N addition had no effect on or even decreased NSC concentration 4,9 . In this study, we found a signi cantly increase in NSC concentration of different organs of R. soongorica within a certain range of N addition (0 -9.2 g N m − 2 year − 1 ), but it had some decreasing in highest N addition (13.8g N m − 2 year − 1 ), this mainly due to signi cant increasing in soluble sugar concentration and reducing in starch concentration, but this nding not supported our third hypothesis and was consistent with the results of other studies 4,32 .…”

“…For example, drought either signi cantly increased or maintained the total NSC concentration in the above-ground organs, but reduced the total NSC concentration in the sapling roots 8 . Compared to without any fertilization, the NSC in leaf, stem, and root of Moringa oleifera seedlings were greatly reduced by N and P fertilization which could be explained by the dilution effects of increased biomass following fertilization 9 . It is seen that NSC and its components (soluble sugar and starch) showed different responses to different environmental factors among different organs 10,11 .…”

Reaumuria soongorica is an important biological barrier for ecological protection in Gobi desert of the Northwest, China, where soil nitrogen availability is low. N deposition increasing significantly in Gobi desert, so that the response of R. soongorica to N enrichment may become a problem. However, little is known the effects of N addition on biomass, non-structural carbohydrates (NSC), and carbon:nitrogen:phosphorus (C:N:P) stoichiometry of R. soongorica in this region. Here, we examined changes in biomass, NSC and C:N:P ratios of different organs for one year growth of R. soongorica at four N treatments which is 0 (N0), 4.6 (N1), 9.2(N2), and 13.8 (N3) g m−2 year−1. The N addition ( reach to 9.2 g m−2 year−1) significantly enhanced the biomass of different organs, meanwhile the belowground:aboveground ratio was also significantly increased. The NSC concentration of root significantly enhanced under N addition treatments, but the stem and leaf NSC concentration was only increased significantly at N1 and N2 addition. N addition only enhanced the soluble sugar concentration of leaf and root, and reduced starch concentration of different organs. The N concentration of stem and root were significantly enhanced at N2 and N3 addition and the leaf N concentration was only increased in N3 addition, but N addition had no significant effect on C and P concentrations. The stem and leaf C:N ratio were reduced significantly in N2 and N3 treatments, but the root C:N ratio was decreased significantly in N addition. The N3 addition significantly increased N:P ratio of different organs. Our results suggested N addition changed the biomass, NSC, N concentration, C:N and N:P ratio of different organs, meanwhile the root responded more strongly than stem or leaf, this is beneficial for absorbing more water in arid soil in this region, then to ensure the survival of R. soongorica seedlings.
