“…The TV of YD4 was significantly higher than that of YD3 and HD5 (Table 1). The eating quality of rice is affected by the amylose, protein, and fat contents [7]. The protein content of rice is related to eating quality [22], and in this study, the protein content of rice was negatively correlated with eating quality (Table S1).…”

“…At present, many studies focus on metabolic gene regulation mechanisms. The oil content of high-quality rice varieties is especially important to the taste of rice [6,7]. Previous studies used GC-MS to identify the composition and content of fatty acids in 533 varieties of cultivated rice seeds and found that various fatty acid components had extensive variation and significant differences among cultivated rice subgroups [8].…”

To understand differences in the quality of different conventional japonica rice varieties and variations in metabolites related to rice quality, the quality of three conventional japonica varieties was determined, and the metabolites of the milled rice were investigated using nontargeted metabolomics technology. The results showed that the taste value (TV) of Yangda 4Hao (YD4) was significantly higher than that of Yangda 3Hao (YD3) and Huaidao 5Hao (HD5). The protein content (PC) of HD5 was significantly higher than that of YD3 and YD4. PC was significantly negatively correlated with TV. Ninety-one differential metabolites (59 increased and 32 decreased) were identified between YD3 and HD5. A total of 144 differential metabolites (96 upregulated and 48 downregulated) were identified between YD4 and HD5. A total of 114 differential metabolites (40 increased and 74 decreased) were identified between YD3 and YD4. The metabolites with a high correlation to rice quality were mostly involved in the amino acid metabolism pathway. Amino acid metabolites play an important role in the formation of rice quality. The key metabolites in the synthesis and regulation of metabolic pathways are sucrose, levan, and amylose, which are carbohydrates, and L-glutamine, L-aspartic acid, and L-asparagine, which are amino acid metabolites. It can be seen from this study that the metabolites of sucrose, levan, amylose, L-glutamine, L-aspartic acid, and L-asparagine may be the key metabolites in the quality formation of high-quality rice varieties.

“…It has been demonstrated that potassium affects seeds' ACCase and FAS activity. For example, a prior investigation on rice ( Oryza sativa L.) revealed that potassium fertilizer application boosted ACCase and FAS activities in its seeds, hence encouraging lipid synthesis in its seeds (Chen, Peng, Li, et al, 2022).…”

Styrax tonkinensis is a promising woody biodiesel species. In this experiment, we investigated how foliar spraying of potassium gluconate solution affected the production of seed oil in S. tonkinensis. Leaf spraying of potassium gluconate solution appreciably promoted the photosynthesis of S. tonkinensis leaves through both the light reaction and the dark reaction. By boosting the activity of enzymes involved in glucose metabolism and seed oil synthesis, foliar spraying of potassium gluconate solution also dramatically enhanced glucose metabolism and seed oil synthesis in the S. tonkinensis seeds. This indicates that foliar spraying with potassium gluconate solution discernibly improved the synthesis of seed oil in S. tonkinensis by encouraging the transit of photosynthetic products from the source to the reservoir and the flow of carbon into the seed oil synthesis in the seeds. Overall, the medium concentration of potassium gluconate solution (4 g/L) was found to be the most effective for increasing the oil content of S. tonkinensis seeds. While higher potassium gluconate solution concentrations (6 g/L) had a slight inhibitory effect on specific indicators (ACCase) during specific seed development periods. This study highlighted the importance of potassium for seed oil synthesis in woody plants and provided a useful foundation for future cultivation practices aimed at enhancing seed oil synthesis in woody plants.

“…Rational application of phosphorus fertilizer can increase crop yield, improve crop quality, promote flowering and fruit of jacket vegetables, and improve results. The research showed that after applying phosphorus fertilizer, the yield of PLI increased with the increase of phosphorus application, and the yield was the highest at the highest phosphorus application [ 18 , 27 ]. In this experiment, there was a significant positive correlation between phosphorus fertilizer and PLI fruit weight, that is, the increase of phosphorus fertilizer would increase PLI fruit weight, possibly because phosphorus would participate in the metabolism and transportation of PLI carbohydrates, which is conducive to the growth of PLI fruit.…”

To investigate the effect of fertilization on Pb content in vegetables, pepper was planted in L1645 (the 5 influencing factors are fertilizers (N, P, K), organic fertilizers (sheep manure) and Pb2+; the 4 levels are blank, low, medium and high; a total of 16 treatments) pot orthogonal experiment. The effects of fertilizers on the growth and Pb content in various parts of pepper under Pb stress were analyzed. The results showed that: (1) The Pb content in pepper fruit ranged from 0.011 mg·kg−1 to 0.085 mg·kg−1, which did not exceed the limit value (0.1 mg·kg−1) in the National Standard for Food Safety-Limit of Contaminants in Food (GB2762-2017); (2) The effect order of fertilization on pepper fruit weight was P2O5 > sheep manure > N > K2O; The horizontal combination of factors that promoted the maximum fruit weight of pepper was N (0.15 g·kg−1), P2O5 (0.225 g·kg−1), K2O (0.15 g·kg−1) and sheep manure (9 g·kg−1); (3) The order of fertilizer effects on Pb content in pepper fruit was Pb2+ > K2O > N = sheep manure > P2O5; the factor level combination that resulted in the maximum Pb content in pepper fruits was N (0.15 g·kg−1), P2O5 (0 g·kg−1), K2O (0.45 g·kg−1), sheep manure (6 g·kg−1) and Pb2+ (350 mg·kg−1); (4) Based on the soil fertility characteristics of Urumqi, the recommended optimal fertilizer application rate was: high phosphorus fertilizer P2O5 (495 kg·hm−2), low-level potassium fertilizer K2O (330 kg·hm−2), medium-level nitrogen fertilizer N (660 kg·hm−2) (or low-level nitrogen fertilizer N (330 kg·hm−2) + high-level organic manure sheep manure (19,800 kg·hm−2), which can achieve high yield while ensuring that the Pb content in the fruits does not exceed the standard. Strengthening control of effective and reasonable fertilization methods in Urumqi agricultural land is helpful to reduce the Pb content in vegetables.
