摘要

本研究采用绿色途径合成了生物源纳米零价铁(bio-nZVI),并将其作为纳米造粒剂用于花生种子萌发和白僵菌生长。扫描电镜(SEM)、傅里叶变换红外(FT-IR)和x射线衍射(XRD)结果表明,bio-nZVI合成成功。合成的生物- nzvi呈球形,尺寸在80 ~ 350 nm之间。制备的生物- nzvi具有核壳结构,核壳结构为Fe0和Fe2O3,该核壳结构被一层从叶提取物中提取的有机层覆盖。将合成的生物- nzvi在10 ~ 320 mg/L浓度范围内施用于花生种子和白Basella植株上,促进种子萌发和植株生长。结果表明,20 ~ 40 mg/L的最佳浓度bio-nZVI能显著提高花生种子萌发率,促进白僵菌生长。然而,高浓度的生物- nzvi溶液对花生种子萌发和白Basella植株生长没有显著的促进作用。这些结果表明,生物nzvi可能是一种有前景的农业萌发促进剂和生态友好型生长促进剂;因此,它在提高作物生产力和满足全球粮食需求方面具有巨大潜力。

Green Synthesis of Biogenic Nano Zerovalent Iron Using Cleistocalyx nervosum Leaf Extract for Enhancing Peanut Seed Germination and Basella alba Growth.

In this study, biogenic nano zerovalent iron (bio-nZVI) was synthesized through a green approach using Cleistocalyx nervosum (C. nervosum) leaf extract for use as a nanopriming agent for improving peanut seed germination and Basella alba growth. The scanning electron microscopy (SEM), Fourier-transform infrared (FT-IR), and X-ray diffraction (XRD) results demonstrated that bio-nZVI was successfully synthesized. The as-synthesized bio-nZVI had a spherical shape with a size ranging from 80 to 350 nm. The prepared bio-nZVI had a core-shell structure with a core of Fe0 and a shell of Fe2O3, and this core-shell structure was covered by an organic layer derived from the leaf extract. The synthesized bio-nZVI was applied to peanut seeds and Basella alba plants at concentrations ranging from 10 to 320 mg/L to enhance seed germination and plant growth. The results demonstrated that bio-nZVI at optimal concentrations of 20-40 mg/L could significantly improve peanut seed germination and promote Basella alba growth. However, no significant effect on enhancing peanut seed germination and Basella alba plant growth was observed when applying a bio-nZVI solution at higher concentrations. These findings suggest that bio-nZVI could be a promising germination promoter and eco-friendly growth enhancer for agricultural applications; thereby, it has great potential for increasing crop productivity and meeting demand for grain worldwide.
