“…It was further confirmed that N accumulation was not only dependent on root morphology but also related to the nitrogen uptake capacity of the germplasm itself. 31 , 32 The adaptive changes in root morphology and physiological response may facilitate different physiological activities, thus promoting the growth of sugar beets with different levels of LN tolerance.…”

“… 23 , 36 , 37 In this study, the reduced N accumulation in leaves ( Figure 6a ) under LN made the leaves yellowish or lighter green ( Figure 1 ), and the chlorophyll content decreased, indicating that the sugar beets were suffering from stress due to inhibited nitrogen assimilation. 22 , 31 Different genotypes showed various chlorophyll and soluble protein contents under low N (Table S2), which may be related to their own LN tolerance capacity and genetic characteristics. Compared with sensitive genotype 92011 (G), nitrogen deficiency did not significantly restrict chlorophyll production in the LN-tolerant genotype 780016B/12 superior (F), and an increase in the dark response of photosynthesis also increased its soluble protein content (Table S2, p < .05 or p < .01).…”

Nitrogen (N) is an essential element required for sugar beet growth. Sugar beets with low N (LN) tolerance and high N use efficiency are excellent materials for breeding. Here, we comprehensively evaluated the morphological and physiological responses of nine sugar beet genotypes to LN supply. It was found that 0.5 mmol·L −1 N (LN) significantly influenced the performance of leaves and the topology of roots by reducing the bioproduction of chlorophyll a (Chl a) and soluble protein (SP) and the accumulation of N in leaves and roots (LNA and RNA), thus differentially restricting the growth (hypocotyl diameter, HD; root length, RL) and biomass (leaf and root fresh weight; LFW and RFW; leaf dry weight, LDW) of these sugar beets. Principal component and cluster analyses showed that 780016B/12 superior (F) exhibited excellent tolerance to LN; it had higher SOD activity (62.70%) and APX activity (188.92%) and a higher proline content (131.82%) than 92011 (G, LN sensitive). These attributes helped 780016B/12 superior (F) to better endure LN stress, and the morphology and N distribution changed to adapt to N deficiency, such that the root length increased by 112.48%, leaf area increased by 101.23%, and leaf nitrogen accumulation reached a peak of 14.13 g/plant. It seems that LN-tolerant genotypes increased their root length and surface area by reducing the difference in biomass, thereby expanding the contact between roots and soil, which was conducive to the absorption of nutrients (N) by sugar beets and helped distribute more assimilation products to the roots.

“…Thus, the photosynthetic carbon sequestration capacity of sacsaoul is higher than that of goji berry under the same photosynthetically effective irradiation conditions. The inter‐root microorganisms around goji berry may also contribute to the nitrogen cycle and further stimulate N 2 O emissions (Shi et al, 2022; Zheng et al, 2010), and therefore contribute to the GWP change.…”

Impact of planting Lycium barbarum L. on the carbon–land–water nexus of a Haloxylon ammodendron nature reserve in the Qaidam basin, China

Desert ecosystems are an important component of terrestrial ecosystems and land use change directly affects their composition and function. However, there have been few studies on how land use change impacts the carbon-land-water nexus in desert ecosystems. We studied the effects of replacing sacsaoul (Haloxylon ammodendron), a typical natural vegetation in the Qaidam basin, China, with artificially planted goji berry (Lycium barbarum L.) using the denitrification-decomposition (DNDC) model. Our results showed that DNDC model coefficient of determination (R 2 ) and Nash-Sutcliffe modelling efficiency (NSE) both reached 0.92 for sacsaoul and goji berry, and the root mean square error (RMSE) of the simulation was 495 kg ha À1 and 116 kg ha À1 for sacsaoul and goji berry, respectively.

To improve plant quality and fertilizing efficiency, we conducted a study to elucidate the effects of nitrogen (N), phosphorous (P), and potassium (K) fertilizers on the growth, nutrient accumulation, and quality of Lagerstroemia indica plants grown in containers and determine the optimal fertilization levels. Both single-factor and multifactor experiments involving N, P, K fertilizers were designed. Integrated with the plant growth, physiological traits, nutrient levels, and other indices, we used a membership function analysis to comprehensively evaluate plant quality. During the single-factor experiments, the best levels of the single fertilizers applied were 8 g/plant N, 2 g/plant P, and 4 g/plant K. We also found that, within a certain range, N, P, and K fertilizers promoted vegetative growth, increased the chlorophyll, soluble sugar, and soluble protein concentrations, and enhanced nutrient accumulation of L. indica. To avoid the wasting of fertilizers and promote plant quality, the optimal application levels were calculated using a regression analysis. The suggested N, P, and K applications were 6.89 g/plant, 1.97 g/plant, and 3.33 g/plant, respectively. Our results revealed that N, P, and K effect the performance of L. indica container plants, which paves the way for developing reliable and precise fertilizing techniques for growing L. indica.
