“…3), indicating that increased NH 4 + absorbed by roots was translocated into leaves, but with a lower leaf assimilation rate (Sousa et al 2021). One of the mechanisms that enables plants to tolerate ion toxicity involves maintaining low ion concentrations in shoots, as evidenced by the frequently observed inverse correlation between shoot ion concentration and plant growth (Rossini-Oliva et al 2018;Lyu et al 2023). Among crop species, varieties that are more tolerant to ion toxicity often have lower ion concentrations in shoots or reduced accumulation in shoots (Kong et al 2022).…”

Ammonium nitrogen (NH4+‐N) is essential for fruit tree growth, but the impact of excess NH4+‐N from fertilizer on evergreen citrus trees is unclear. In a climate chamber, 8‐month‐old citrus plants were exposed to five different hydroponic NH4+‐N concentrations (0, 5, 10, 15 and 20 mm) for 1 month to study effects of NH4+‐N on growth characteristics, N uptake, metabolism, antioxidant enzymes and osmotic regulatory substances. Application of 10 mm NH4+‐N adversely affected root plasma membrane integrity, root physiological functions, and plant biomass. MDA, CAT, POD, APX and SOD content were significantly correlated with leaf N metabolic enzyme activity (GOGAT, GDH, GS and NR). GDH was the primary enzyme involved in NH4+‐N assimilation in leaves, while the primary pathway involved in roots was GS‐GOGAT. Under comparatively high NH4+ addition, roots were the main organs involved in NH4+ utilization in citrus seedlings. Our results demonstrated that variations in NH4+ concentration and enzyme activity in various organs are associated with more effective N metabolism in roots than in leaves to prevent NH4+ toxicity in evergreen woody citrus plants. These results provide insight into the N forms used by citrus plants that are important for N fertilizer management.

Our research group successfully designed the F. carica and Taxus cuspidata Sieb. et Zucc mixed forest, and confirmed that their interspecific relationship was stable and F. carica has a promoting effect on neighboring T. cuspidata growth. However, the promoting mechanism has not been elucidated. In this study, F. carica was used as the donor plant and T. cuspidata was used as the recipient plant. T. cuspidata seedlings were irrigated with F. carica root extracts of different concentrations (10.0, 20.0, 40.0 g·L−1), and the plant height, base diameter, photosynthetic parameters, photosynthetic pigments, MDA contents, and antioxidant enzyme activities were measured. Soil physical and chemical properties, enzyme activities, and microbial diversity were measured. The results showed that the abundance of growth-promoting bacteria increased and the number of pathogenic bacteria decreased in the rhizosphere of T. cuspidata soil. It was speculated that the chemicals secreted by F. carica roots interacted with soil microorganisms of T. cuspidata soil after enrichment, changed soil microbial diversity, and indirectly promoted the growth of T. cuspidata. UPLC-QTOF-MS/MS was used to analyze F. carica root water extract and F. carica root exudates, respectively, and it was found that the main components were similar. Therefore, the promoting effect of F. carica on T. cuspidata is mainly caused by the accumulation of potential chemicals in F. carica root exudates in the soil through interaction with soil microorganisms. Furthermore, the allelopathic-promoting mechanism of F. carica on T. cuspidata was discussed from various aspects, to provide a theoretical basis for the protection, breeding, and sustainable management of T. cuspidata resources.

“…Mg is involved in chlorophyll synthesis, photosynthesis, protein synthesis, and enzyme activation (Aboyeji et al, 2019; Cowan, 2002; Hawkesford et al, 2023; Kumari et al, 2022). In addition, it can also improve plant resistance to high temperature, drought, strong light, and reduce abiotic stressors like aluminum (Al) toxicity, heavy metal stress, and salt stress (Boaretto et al, 2020; Lyu et al, 2023). Therefore, an in‐depth understanding of the composition, changes, and potential regulatory factors of K, Ca, and Mg in plants is extremely important for the study of plant physiology and biogeochemical cycles.…”

Grasping how climate change will affect the tropical region's leaf potassium, calcium, and magnesium content is pivotal for enhancing our comprehension of plant stoichiometry. Currently, there is limited research on leaf potassium, calcium, and magnesium in tropical plants, which is particularly evident with the increasing importance of tropical rainforest biodiversity studies. This study investigated the impact of geographical and climatic factors on the leaf potassium, calcium, and magnesium content in 346 plants (including woody plants, herbs, and vines) on Hainan Island. The findings demonstrated that the average leaf potassium, calcium, and magnesium contents were 5.77, 11.86, and 2.92 mg·g−1, respectively, which were less than that in the Chinese flora. Mean annual precipitation (MAP) has a promoting effect on leaf potassium content (p < 0.05), suggesting that artificial potassium fertilization is needed due to the increasing MAP. Leaf potassium and magnesium content were positively correlated with latitude (p < 0.05) and longitude (p < 0.01); and there was a negative correlation between leaf calcium content and latitude (p < 0.05), showing that geographical factors have a significant impact on the potassium, calcium, and magnesium content of plant leaves. Additionally, the variables regulating leaf potassium, calcium, and magnesium varied across woody plants, herbs, and vines. Therefore, it is necessary to make corresponding adjustments according to local conditions and the plant functional types during nutrient management. In conclusion, this study sheds light on their potential responses to global changes and is instrumental in informing the management of these nutrients in tropical rainforest plants.
