摘要

甜菜(Beta vulgaris L.)易患各种疾病，特别是白粉病，由甜菜Erysiphe引起。在农业中使用纳米技术可以通过提供快速疾病诊断和抗病的新工具来彻底改变该部门。本研究通过两个实验探讨了锌纳米颗粒诱导甜菜植株抗白粉病的潜力。第一个试验评价了甜菜品种对白粉病的敏感性，其中美洲狮对白粉病的抗性最强，Top最敏感。第二个试验考察了锌NPs对诱导白粉病抗性的影响。在叶面施用浓度分别为100ppm、50ppm和10ppm的氧化锌纳米粒子(ZN)和硫酸锌(ZS)。结果表明，与对照相比，大多数处理显著提高了叶绿素a、b、总叶绿素、总可溶性糖、内源H2O2水平以及过氧化物酶(POD)和多酚氧化酶(PPO)活性，降低了白粉病的严重程度、脂质过氧化(MDA)、酚类物质浓度和过氧化氢酶活性，特别是在100和50 ppm浓度下的Zn活性。锌NPs诱导抗白粉病的生理作用归因于活性氧(ROS)的产生和积累以及PPO和/或POD催化的酚类化合物的氧化反应。研究结果表明，100 ppm和50 ppm的ZnO纳米颗粒可以作为叶片喷雾，通过诱导甜菜杆菌对甜菜的抗性来减少甜菜植物生物胁迫的有害影响。

Enhancing Sugar Beet Plant Health with Zinc Nanoparticles: A Sustainable Solution for Disease Management

Sugar beet (Beta vulgaris L.) is susceptible to various diseases, especially powdery mildew, caused by Erysiphe betae. Using nanotechnology in agriculture could revolutionize the sector by providing new tools for fast disease diagnosis and disease resistance. This study investigated the potential of Zn nanoparticles in inducing resistance to powdery mildew in sugar beet plants through two experiments. The first experiment assessed the susceptibility of sugar beet cultivars to powdery mildew, with Puma being the most resistant and Top being the most susceptible. The second experiment examined the impact of Zn NPs in inducing resistance to powdery mildew. Zinc-oxide nanoparticles (ZN) and zinc sulfate (ZS) at concentrations of 100, 50 and 10 ppm were used as foliar applications. The results showed that most treatments significantly increased levels of chlorophyll a, b, and total chlorophyll, total soluble sugars, endogenous H2O2, and activity of peroxidase (POD) and polyphenol oxidase (PPO), while reducing the severity of powdery mildew disease, lipid peroxidation (MDA), phenolics concentrations and catalase activity, especially Zn at concentrations of 100 and 50 ppm compared to infected control. The physiological role of Zn NPs in inducing resistance against powdery mildew disease is attributed to the production and accumulation of reactive oxygen species (ROS) and oxidative reactions of phenolic compounds catalyzed by PPO and/or POD. Our results suggested that ZnO nanoparticles at 100 and 50 ppm can be used as a foliar spray to reduce the harmful impacts of biotic stress caused by E. betae in sugar beet plants by inducing resistance to the pathogen.

期刊介绍： Journal of Soil, Plant and Environment is an open peer-reviewed journal that considers articles and review articles on all aspects of agricultural sciences. Aim and Scope Journal of Soil, Plant and Environment (ISSN: 2957-9082) is an international journal dedicated to the advancements in agriculture throughout the world. The goal of this journal is to provide a platform for scientists, students, academics and engineers all over the world to promote, share, and discuss various new issues and developments in different areas of agricultural sciences. All manuscripts must be prepared in English and are subject to a rigorous and fair peer-review process. Accepted papers will appear online within 3 weeks followed by printed hard copy. Journal of Soil, Plant and Environment (ISSN: 2957-9082) publishes original papers including but not limited to the following fields: Soil–plant relationships; crop science; soil science; biometry; crop, soil, pasture, and range management; crop, forage, and pasture production and utilization; turfgrass; agroclimatology; agronomic models; integrated pest management; integrated agricultural systems; and various aspects of entomology, weed science, animal science, plant pathology, and agricultural economics as applied to production agriculture. We are also interested in: 1) Short Reports– 2-5 pages where the paper is intended to present either an original idea with theoretical treatment or preliminary data and results; 2) Book Reviews – Comments and critiques of recently published books in agricultural sciences.
