Abstract

Background: It is known that 60-80% of the population affected by various diseases, such as heart attack, stroke, and oncological diseases is associated with selenium (Se) deficiency. Therefore, enriching agricultural crops with Se is considered a current issue. Objective: This study investigates Se enrichment of Lycium barbarum (Lb) and its effectiveness in hydroponic and soil conditions in the Ararat Valley. The research focuses on the impact of adding exogenous Se on plant productivity, Se accumulation, and the content of biologically active substances (BAS) in Lb berries and leaves. Methods: The experiments were conducted from 2021 to 2023 using hydroponic and soil cultivation methods with varying Se concentrations in nutrient solutions and foliar nutrition. Results: The results demonstrate that Se enrichment significantly increased Se and BAS levels in both leaves and berries of Lb, with hydroponic cultivation exhibiting higher accumulation compared to soil conditions. Foliar feeding with a 0.005% Se solution and exogenous Se addition to nutrient solutions at 1.0 mg/L resulted in notable improvements in Se content and plant productivity. Furthermore, the analyses revealed significant differences between hydroponically and soil-grown Lb, emphasizing the potential of hydroponic cultivation for producing Se-enriched plant material with enhanced BAS content. Conclusion: Hydroponic cultivation supplemented with Se and foliar nutrition is recommended for obtaining Se-rich Lb plant material, which is suitable for medicinal and functional food purposes. These findings contribute to the development of biotechnologies for Se -enriched plant production and addressing health and nutritional needs. Keywords: Goji, berries, biologically active substances, flavonoids, phenolic acids, tannins, carotenoids

阿拉拉特河谷水培和土壤条件下枸杞的功效和富硒作用

背景：众所周知，患心脏病、中风和肿瘤等各种疾病的人群中有 60-80% 与硒（Se）缺乏有关。因此，让农作物富含 Se 被认为是当前的一个问题。研究目的本研究调查了枸杞（Lb）的硒富集及其在阿拉拉特山谷水培和土壤条件下的有效性。研究重点是添加外源 Se 对植物生产力、Se 积累以及枸杞浆果和叶片中生物活性物质 (BAS) 含量的影响。研究方法实验时间为 2021 年至 2023 年，采用水培和土壤栽培方法，在营养液和叶面营养液中添加不同浓度的 Se。结果结果表明，富集 Se 能显著提高枸杞叶片和浆果中的 Se 和 BAS 含量，与土壤条件相比，水培法的积累量更高。叶面喷施 0.005% 的 Se 溶液和在营养液中添加 1.0 mg/L 的外源 Se 可显著提高 Se 含量和植物生产力。此外，分析表明水培枸橘和土培枸橘之间存在显著差异，强调了水培在生产富含 Se 的植物材料和提高 BAS 含量方面的潜力。结论建议水培并辅以 Se 和叶面营养，以获得富含 Se 的枸杞植物材料，这种材料适用于药用和功能性食品。这些发现有助于开发富含 Se 的植物生产生物技术，满足健康和营养需求：枸杞、浆果、生物活性物质、类黄酮、酚酸、单宁、类胡萝卜素

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
