“…It is excellent source of nutrients and phytochemicals, including ascorbic acid, carotenoids, flavonoids and essential oils (EOs), which are often used in traditional medicine [ 7 , 8 ]. Ganzhou City in Jiangxi Province is the main region for the production of navel oranges in China, and the Newhall navel orange is the predominant variety, accounting for over 80% of the total product [ 9 , 10 ]. Newhall navel orange trees produce large amounts of fruit that are subject to physiological fruit drop each year [ 11 ].…”

Nanfeng mandarins (Citrus reticulata Blanco cv. Kinokuni), Xunwu mandarins (Citrus reticulata Blanco), Yangshuo kumquats (Citrus japonica Thunb) and physiologically dropped navel oranges (Citrus sinensis Osbeck cv. Newhall) were used as materials to extract peel essential oils (EOs) via hydrodistillation. The chemical composition, and antibacterial and antioxidant activities of the EOs were investigated. GC-MS analysis showed that monoterpene hydrocarbons were the major components and limonene was the predominate compound for all citrus EOs. The antibacterial testing of EOs against five different bacteria (Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Salmonella typhimurium) was carried out using the filter paper method and the broth microdilution method. Kumquat EO had the best inhibitory effect on B. subtilis, E. coli and S. typhimurium with MIC (minimum inhibitory concentration) values of 1.56, 1.56 and 6.25 µL/mL, respectively. All citrus EOs showed the antioxidant activity of scavenging DPPH and ABTS free radicals in a dose-dependent manner. Nanfeng mandarin EO presented the best antioxidant activity, with IC50 values of 15.20 mg/mL for the DPPH assay and 0.80 mg/mL for the ABTS assay. The results also showed that the antibacterial activities of EOs might not be related to their antioxidant activities.

“…The nutrient concentrations stored in the new shoots and fruits during the developmental stage was closely related to the yield of citrus fruits [4,15]. The biomass and nutrient accumulations in citrus shoots were increased with the yield level (Figure 3).…”

“…Therefore, numerous studies have reported that mineral nutrients play a vital role in citrus tree growth, fruit yield and quality formation [2,3]. For example, nitrogen (N) and potassium (K) are the two 2 of 11 most accumulated nutrients in citrus fruits [4]; phosphate (P) promotes the growth of citrus trees [5]; and calcium (Ca) reduces the effects of copper stress on citrus roots and leaves [6], magnesium (Mg) deficiency induces swelling, cracking and lignification of leaf veins [7]. In addition, the alternate bearing phenomenon of citrus trees is also closely related to nutrient demand and distribution, which seriously affect the citrus yield [8,9].…”

“…Although citrus leaves account for only 21% of the above-ground biomass, they contain a high proportion (31-44%) of above-ground nutrients [13]. Previous studies have shown that N in fertilizers is mainly distributed in citrus shoots, leaves and fruits [14] and citrus fruits have a high demand for microelement during development, and there is a strong linear relationship between dry matter yield and nutrient accumulation [4]. The new organs of citrus trees (annual leaves, twigs and fruits) are the most active parts of mineral nutrition, which are closely related to the formation of yield and lay the nutrient foundation for flowering and fruiting in the coming year [4,15].…”

In non-fruiting citrus trees, the concentration of N in the leaves of citrus in spring and summer tends to decrease, and half of the 15 N annually absorbed by citrus is allocated to new organs [16].…”

Fruit Yields Depend on Biomass and Nutrient Accumulations in New Shoots of Citrus Trees

et al. 2020

New shoots (including newly formed leaves and twigs) and fruits of citrus tree are key organs for present yield formation and flower differentiation in the next season, but the relationship between yield fluctuation and accumulations of major nutrients in new shoots and fruits of citrus tree is still unclear. Thus, to quantify the biomass and mineral nutrient accumulation in new shoots and fruits of citrus trees under varied yield levels has essential significance for rational fertilization and pruning management for citrus orchards. The purpose of this study was, therefore, to investigate the accumulation of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca) and magnesium (Mg), and the distribution of biomass in new shoots and fruits of citrus trees under low, medium and high-yield levels in each of eight orchards located in Chongqing, China. The results showed that substantial variation of fruit yield was observed in all eight orchards with an average yield of 15.0 (low), 30.9 (medium) and 60.1 (high) kg/plant. The averaged biomass of new shoots ranged from 1.59 to 2.51 kg/plant, which was significantly and positively correlated with fruit yield. Nutrient accumulation in leaves was generally highest among new organs, while more than half of N (52.70–71.4%), P (66.5–80.4%) and K (68.9–85.9%) accumulated in fruit. Fruit yields closely correlated with total amounts of major nutrients in new shoots. Furthermore, the nutrient requirements per unit of newly developed shoots and fruits were gradually decreased with increased yield, but the removed nutrients per ton of fresh fruit were almost stable, indicating that more nutrients were distributed into fruit tissues. Taken together, these findings are valuable for optimizing nutrient and pruning management in citrus orchards in China and other similar countries.
