Abstract

The optimal nutritional regime (application of the compound fertilizer at small doses), humidity and temperature conditions, and pH values (weakly alkaline) reduce the content of ascorbic acid (a protective antioxidant compound) in Solanum tuberosum L. tubers. Exogenous antioxidants (humic preparations) can be used to maintain the level of ascorbic acid in commercial products. Field experiments were conducted on two soil types and in two climatic regions (Voronezh and Moscow oblasts). The obtained data indicate that the application of humic preparations (Life Force Natural Humic Acids used in organic farming, Gumistar, and BIO-complex) and lichen-based Yagel-DETOX, both solely and in combination with the mineral fertilizer, maintains the ascorbic acid level (i.e., prevents its reduction) and increases the yield.

以抗坏血酸为例的生理活性制剂对马铃薯（Solanum tuberosum L.）抗氧化特性的影响

摘要

最佳营养方案（小剂量施用复合肥）、湿度和温度条件以及 pH 值（弱碱性）会降低马铃薯中抗坏血酸（一种保护性抗氧化剂化合物）的含量L.块茎。外源抗氧化剂（腐殖质制剂）可用于维持商业产品中抗坏血酸的水平。在两种土壤类型和两个气候地区（沃罗涅日州和莫斯科州）进行了现场实验。获得的数据表明，单独使用腐植酸制剂（有机农业中使用的 Life Force 天然腐植酸、Gumistar 和 BIO 复合物）和基于地衣的 Yagel-DETOX，无论是单独使用还是与矿物肥料结合使用，都可以保持抗坏血酸水平（即防止其减少）并增加产量。
