Abstract

BACKGROUND

This study investigates a novel idea about the foliar application of nanoparticles as nanofertilizer combined with a natural stimulant, blue-green algae Spirulina platensis L. extract, as a bio-fertilizer to achieve safety from using nanoparticles for enhancement of the growth and production of the plant. Thus, this experiment aimed to chemically synthesize copper nanoparticles via copper sulfate in addition to evaluate the impact of CuNPs at 500, 1000, and 1500 mg/L and the combination of CuNPs with or without microalgae extract at 0.5, 1, and 1.5 g/L on the morphological parameters, photosynthetic pigments accumulation, essential oil production, and antioxidant activity of French basil.

RESULTS

The results revealed that foliar application of CuNPs and its interaction with spirulina extract significantly increased growth and yield compared with control, the treatments of 1000 and 1500 mg/L had less impact than 500 mg/L CuNPs. Plants treated with 500 mg/L CuNPs and 1.5 g/L spirulina extract showed the best growth and oil production, as well as the highest accumulation of chlorophylls and carotenoids. The application of CuNPs nanofertilizer caused a significant increase in the antioxidant activity of the French basil plant, but the combination of CuNPs with spirulina extract caused a decrease in antioxidant activity.

CONCULOSION

Therefore, foliar application of natural bio-fertilizer with CuNPsis necessary for obtaining the best growth and highest oil production from the French basil plant with the least damage to the plant and the environment.

摘要

背景

本研究提出了一个新颖的想法，即将纳米颗粒作为纳米肥料应用于叶片，并结合蓝绿藻螺旋藻提取物作为生物肥料，以实现使用纳米颗粒促进植物生长和生产的安全性。因此，本实验旨在通过硫酸铜化学合成铜纳米颗粒，并评估 CuNPs 在 500、1000 和 1500 mg/L 以及 CuNPs 与或不与微藻提取物在 0.5、1 和 1.5 g/L 下对法国罗勒的形态参数、光合色素积累、精油产量和抗氧化活性的影响。

结果

结果表明，与对照相比，叶面喷施 CuNPs 及其与螺旋藻提取物的相互作用显著促进了生长和产量的增加，1000 和 1500 mg/L 的处理比 500 mg/L 的 CuNPs 影响较小。用 500 mg/L 的 CuNPs 和 1.5 g/L 的螺旋藻提取物处理的植物表现出最佳的生长和产油量，以及最高的叶绿素和类胡萝卜素积累。CuNPs 纳米肥料的应用显著提高了法国罗勒植物的抗氧化活性，但 CuNPs 与螺旋藻提取物的结合会降低抗氧化活性。
