Abstract

Background

Efficient agronomic approaches should be developed to alleviate iron (Fe) deficiency in lime-rich soils.

Aims

The present study aimed to investigate the efficiency of eco-friendly synthesized Fe-aminochelates in remediating Fe deficiency and improving the yield and nutritional quality of sunflower (Helianthus annuus L.), compared to FeSO₄ in calcareous soil.

Methods

Fe (glycine)₂ [Fe (Gly)₂] and Fe (methionine)₂ [Fe (Met)₂] aminochelates were synthesized and characterized via a CHN analyzer, H¹ NMR and FT-IR spectroscopy. In a field experiment, Fe-aminochelates and FeSO₄ were applied using three methods (priming, fertigation, and foliar spray) at various plant growth stages.

Results

The application of [Fe (Gly)₂] and [Fe (Met)₂] through different methods significantly improved the biomass yield, nutritional quality, and yield attributes, compared with those of FeSO₄. Compared with the control, foliar application of [Fe (Met)₂] increased seed yield (73.9%), oil yield (125.8%), and seed protein content (60%). In addition, antioxidant enzyme activities, total soluble protein (TSP), and seed nutrients such as Fe, N, and S concentrations, as well as the Fe concentration in leaves, also increased in response to [Fe (Gly)₂] and [Fe (Met)₂] application, whereas the N/S ratio decreased with increasing seed oil content.

Conclusions

These results suggest that the application of Fe-aminochelates may be a promising way to promote Fe biofortification and overcome Fe deficiency under calcareous conditions.

铁-氨基螯合物在向日葵钙质土壤中铁（铁）的生物强化

背景：应开发有效的农艺方法来缓解富石灰土壤中的铁（Fe）缺乏。目的研究生态友好型合成氨螯合铁（Fe-aminochelates）与硫酸铁（FeSO₄）在钙质土壤中修复向日葵（Helianthus annuus L.）缺铁、提高产量和营养品质的效果。方法合成Fe（甘氨酸）2 [Fe (Gly)2]和Fe（蛋氨酸）2 [Fe (Met)2]氨基螯合物，并通过CHN分析仪、H1 NMR和FT-IR光谱对其进行表征。在田间试验中，采用三种施肥方法（灌浆、施肥和叶面喷施）在植物生长的不同阶段施用氨螯合铁和硫酸铁。结果与FeSO4相比，不同方式施用[Fe (Gly)2]和[Fe (Met)2]显著提高了产量、营养品质和产量属性。与对照相比，叶面施用[Fe (Met)2]提高了种子产量（73.9%）、油分产量（125.8%）和种子蛋白质含量（60%）。施用[Fe (Gly)2]和[Fe (Met)2]后，抗氧化酶活性、总可溶性蛋白（TSP）、籽粒铁、氮、硫等营养物质浓度以及叶片铁含量均显著升高，氮硫比随籽粒含油量的增加而降低。结论铁胺螯合物的应用可能是促进铁生物强化和克服钙化条件下铁缺乏的有效途径。

期刊介绍： Established in 1922, the Journal of Plant Nutrition and Soil Science (JPNSS) is an international peer-reviewed journal devoted to cover the entire spectrum of plant nutrition and soil science from different scale units, e.g. agroecosystem to natural systems. With its wide scope and focus on soil-plant interactions, JPNSS is one of the leading journals on this topic. Articles in JPNSS include reviews, high-standard original papers, and short communications and represent challenging research of international significance. The Journal of Plant Nutrition and Soil Science is one of the world’s oldest journals. You can trust in a peer-reviewed journal that has been established in the plant and soil science community for almost 100 years. Journal of Plant Nutrition and Soil Science (ISSN 1436-8730) is published in six volumes per year, by the German Societies of Plant Nutrition (DGP) and Soil Science (DBG). Furthermore, the Journal of Plant Nutrition and Soil Science (JPNSS) is a Cooperating Journal of the International Union of Soil Science (IUSS). The journal is produced by Wiley-VCH. Topical Divisions of the Journal of Plant Nutrition and Soil Science that are receiving increasing attention are: JPNSS – Topical Divisions Special timely focus in interdisciplinarity: - sustainability & critical zone science. Soil-Plant Interactions: - rhizosphere science & soil ecology - pollutant cycling & plant-soil protection - land use & climate change. Soil Science: - soil chemistry & soil physics - soil biology & biogeochemistry - soil genesis & mineralogy. Plant Nutrition: - plant nutritional physiology - nutrient dynamics & soil fertility - ecophysiological aspects of plant nutrition.
