Abstract

The appropriate concentration of the nutrient solution (NS) plays an important role in the yield, antioxidant capacity, and biochemical compounds of basil microgreens in the floating system. This study examined the impact of five different concentrations of Hoagland’s NS (25%, 50%, 75%, 100%, and 125%) on the antioxidant capacity, biochemical compounds, and yield of four basil cultivars and genotypes (Persian Ablagh, Violeto, Kapoor and Red Rubin) in a floating system, utilizing a split plots designs. Results revealed that the highest yield was achieved with a 50% NS concentration. The Persian Ablagh genotype, under a 125% NS concentration, exhibited the highest content of carotenoids, flavonoids, phenolic compounds, and antioxidant potential index (APCI). The Violeto cultivar at a 100% NS concentration produced the highest amounts of vitamin C and anthocyanin. The Kapoor cultivar, when grown with a 100% NS concentration, demonstrated the greatest antioxidant capacity. The nutrient solution with 125% concentration compared to 50% concentration reduced the yield by 23.29%. Also, the performance of the Violeto cultivar increased by 36.24% compared to the red variety of Robin. According to the APCI index, the genotype of Iranian Ablaq basil increased by 152.79% in the treatment of nutrient solution with a concentration of 125% compared to 50%. In this study, yield and total chlorophyll showed a significant negative correlation. A significant positive correlation was observed between vitamin C content and flavonoids, anthocyanin, phenolic compounds, and antioxidant capacity. Anthocyanin content exhibited a positive and significant correlation with the APCI. Based on these findings, we recommend a 50% NS concentration of Hoagland’s NS for optimal yield, a 125% NS concentration for the production of secondary metabolites with enhanced antioxidant capacity, and a 100% NS concentration as a balance between antioxidant properties and yield for basil microgreens production in a floating system.

罗勒微型蔬菜平衡产量和抗氧化能力:漂浮系统中营养液浓度的探索

适宜的营养液浓度对漂浮体系中罗勒微绿叶的产量、抗氧化能力和生化成分有重要影响。本研究采用分割区设计，研究了五种不同浓度的Hoagland’s NS(25%、50%、75%、100%和125%)对漂浮系统中4个罗勒品种和基因型(波斯阿布拉格、紫罗兰、卡普尔和红鲁宾)的抗氧化能力、生化化合物和产量的影响。结果表明，当硝态氮浓度为50%时，产率最高。在125% NS处理下，波斯Ablagh基因型的类胡萝卜素、类黄酮、酚类化合物含量和抗氧化潜力指数(APCI)最高。在100% NS浓度下，紫罗兰品种产生的维生素C和花青素含量最高。卡普尔品种在100% NS浓度下生长时，表现出最大的抗氧化能力。与50%浓度的营养液相比，125%浓度的营养液产量降低了23.29%。与红色品种相比，紫色品种的生产性能提高了36.24%。根据APCI指数，在125%浓度的营养液处理下，伊朗Ablaq罗勒基因型比50%浓度处理提高了152.79%。在本研究中，产量与总叶绿素呈显著负相关。维生素C含量与黄酮类化合物、花青素、酚类化合物和抗氧化能力呈正相关。花青素含量与APCI呈极显著正相关。基于这些发现，我们推荐50%的Hoagland’s NS浓度为最佳产量，125%的NS浓度为产生具有增强抗氧化能力的次级代谢物，100%的NS浓度为浮动体系中罗勒微绿生产的抗氧化性能和产量之间的平衡。
