Abstract

Zinc (Zn) biofortification in food plants presents a good strategy to address inadequate Zn intake by humans, a major health concern. Unconventional food plants (UFPs), known for their rich nutritional profile, offer an accessible and nutritious alternative to the food system. This study evaluated the response of selected UFP species to Zn application. An experiment with a completely randomized design was conducted using a 5 × 3 × 2 factorial scheme with four replicates. Five UFP species: cf. L (Lc), (Pa), (Ra), (Sb), and (Tm) were tested with three Zn doses (0, 2, and 10 kg ha) and two application methods (soil and foliar). The parameters evaluated included leaf number, chlorophyll content, fresh and dry mass, moisture, and mineral content. Foliar application proved to be the more efficient method, with Ra and Sb showing the greatest Zn accumulation. Kohonen's self-organizing maps efficiently explored correlations and groupings, revealing that Zn application influenced these attributes. Biofortified leaves of UFPs show strong potential in mitigating Zn nutritional deficiencies.

摘要

粮食作物中的锌(Zn)生物强化是解决人类锌摄入量不足这一重大健康问题的良好策略。非传统粮食作物(UFPs)以其丰富的营养成分而闻名,为粮食系统提供了一种易于获取且营养丰富的选择。本研究评估了选定的非传统粮食作物品种对锌施用的反应。采用完全随机设计进行实验,使用5×3×2析因方案,重复四次。测试了五个非传统粮食作物品种:cf. L(Lc)、(Pa)、(Ra)、(Sb)和(Tm),设置了三种锌剂量(0、2和10 kg/公顷)和两种施用方法(土壤施用和叶面喷施)。评估的参数包括叶片数量、叶绿素含量、鲜重和干重、水分以及矿物质含量。叶面喷施被证明是更有效的方法,其中Ra和Sb表现出最大的锌积累量。Kohonen自组织映射有效地探索了相关性和分组情况,表明锌的施用影响了这些属性。非传统粮食作物的生物强化叶片在缓解锌营养缺乏方面具有强大潜力。
