Ethephon Reduces Maize Nitrogen Uptake but Improves Nitrogen Utilization in Zea mays L
Front Plant Sci 2022 Jan 11;12:762736.PMID:35087544DOI:10.3389/fpls.2021.762736.
Increasing use of plant density or/and nitrogen (N) application has been introduced to maize production in the past few decades. However, excessive planting density or/and use of fertilizer may cause reduced N use efficiency (NUE) and increased lodging risks. Ethephon application improves maize lodging resistance and has been an essential measure in maize intensive production systems associated with high plant density and N input in China. Limited information is available about the effect of Ethephon on maize N use and the response to plant density under different N rates in the field. A three-year field study was conducted with two Ethephon applications (0 and 90 g ha-1), four N application rates (0, 75, 150, and 225 kg N ha-1), and two plant densities (6.75 plants m-2 and 7.5 plants m-2) to evaluate the effects of Ethephon on maize NUE indices (N agronomic efficiency, NAE; N recovery efficiency, NRE; N uptake efficiency, NUpE; N utilization efficiency, NUtE; partial factor productivity of N, PFPN), biomass, N concentration, grain yield and N uptake, and translocation properties. The results suggest that the application of Ethephon decreased the grain yield by 1.83-5.74% due to the decrease of grain numbers and grain weight during the three experimental seasons. Meanwhile, lower biomass, NO 3 - and NH 4 + fluxes in xylem bleeding sap, and total N uptake were observed under Ethephon treatments. These resulted in lower NAE and NUpE under the Ethephon treatment at a corresponding N application rate and plant density. The Ethephon treatment had no significant effects on the N concentration in grains, and it decreased the N concentration in stover at the harvesting stage, while increasing the plant N concentration at the silking stage. Consequently, post-silking N remobilization was significantly increased by 14.10-32.64% under the Ethephon treatment during the experimental periods. Meanwhile, NUtE significantly increased by Ethephon.
Peer review of the pesticide risk assessment of the active substance Ethephon
EFSA J 2023 Jan 31;21(1):e07742.PMID:36742463DOI:10.2903/j.efsa.2023.7742.
The conclusions of the European Food Safety Authority (EFSA) following the peer review of the initial risk assessments carried out by the competent authorities of the rapporteur Member State, the Netherlands and co-rapporteur Member State, the United Kingdom, for the pesticide active substance Ethephon are reported. The context of the peer review was that required by Commission Implementing Regulation (EU) No 844/2012, as amended by Commission Implementing Regulation (EU) No 2018/1659. The conclusions were reached on the basis of the evaluation of the representative use of Ethephon as a plant growth regulator on cereals (winter and spring barley, winter and spring wheat, winter rye, winter triticale, spelt, durum wheat). The reliable endpoints appropriate for use in regulatory risk assessment are presented. Missing information identified as being required by the regulatory framework is listed. Concerns are reported where identified.
Effects of Ethephon on serum levels of sex hormone, apoptosis, and cell cycle of ovaries in mice
Endokrynol Pol 2022;73(2):346-352.PMID:35593683DOI:10.5603/EP.a2022.0025.
Introduction: The effects of Ethephon on the reproductive systems of mammalian females are still ambiguous. This study was conducted to evaluate the toxic effects of Ethephon on the female reproductive system. Material and methods: Forty female C57 mice were used as experimental subjects and evenly divided into 8 groups, which were fed with mixed Ethephon (0, 107.3, 214.5, and 429 mg/kg bw/day) and pure water. After 20 and 40 days of gavage, the mice were weighed and individual organ coefficients of the ovaries were measured. Enzyme-linked immunoassay was used to detect the serum levels of serum sex hormones. The cell cycle distribution and rate of apoptosis of mouse ovarian tissues were examined using flow cytometry. Results: Ethephon intoxication significantly decreased serum levels of progesterone (P) and oestradiol (E2) and increased the serum levels of luteinizing hormone (LH). The serum levels of follicle-stimulating hormone (FSH) decreased and then increased over time. In addition, Ethephon significantly inhibited the apoptosis rate in the ovary and caused G0/G1 and G2/M arrest. Conclusion: These results indicate that prolonged exposure to Ethephon may have negative effects on the female reproductive system.
Effects of Ethephon on Ethephon residue and quality properties of chili pepper during pre-harvest ripening
J Food Sci Technol 2021 Jun;58(6):2098-2108.PMID:33967308DOI:10.1007/s13197-020-04719-5.
The application of Ethephon was investigated to examine its effects on both Ethephon residue and quality properties of chili peppers during pre-harvest ripening with the goal of facilitating maximum commercial harvest along with improving color and flavor. A single Ethephon treatment significantly increased L* and a* values and capsanthin concentration, while decreased total chlorophyll contents. Moreover, Ethephon treatment induced significant promotion of capsaicin synthesis and reduction of soluble sugar content. While repeated treatments did not increase the total capsaicin content, and the consumption of soluble sugar was accelerated. Additionally, the maximum Ethephon residue in chili pepper after Ethephon treatment was 21.18 mg kg-1, which is lower than the permissible residue level of 50 mg kg-1 for chili peppers. The Ethephon residual decreased with prolonging harvest time of chili peppers. The effects of Ethephon treatment on different types of chili peppers were variable. The results of this study indicated that Ethephon could hasten the ripening process and increase the quality of chili peppers.
Ethephon foliar application: Impact on the phenolic and technological Tempranillo grapes maturity
J Food Sci 2021 Mar;86(3):803-812.PMID:33590528DOI:10.1111/1750-3841.15570.
In recent years, there has been increasing concern about the impact of climate change on viticulture, in particular regarding its influence on grape maturity and quality. Extensive research has shown that the rise of temperatures during grape ripening accelerates the accumulation of sugars while reducing the synthesis of phenolic and aromatic compounds. The aim of this study was to investigate whether the foliar application of the plant growth regulator Ethephon might delay technological grape maturity and increase grape phenolic content, improving wine quality. For this, different concentrations of Ethephon were applied during two vintages to the Tempranillo grape variety at the onset of veraison. Results showed that grape sugar accumulation was delayed in one of the two vintages, whereas the treatment favored the accumulation of phenolic compounds in both vintages. In conclusion, the application of Ethephon at the onset of veraison to Tempranillo grapevines helped to couple grape phenolic and technological maturity, leading to more balanced wines, either by delaying sugar accumulation or by enhancing the synthesis of anthocyanins and phenolic compounds. PRACTICAL APPLICATION: Due to the current climate change, phenolic maturity of grapes does not match with their technological maturity, which means that harvested grapes are usually very sweet but without enough color and aroma. The foliar application of the plant growth regulator-ethephon-delays technological grape maturity and increases grape phenolic content, improving wine quality and creating wines that are more balanced.
