ABSTRACT

This study aimed to investigate the interaction effects of iron oxide nanoparticle (nα-Fe2O3) and its bulk counterpart (bα-Fe2O3) with and/or without citrate interaction on germination and seedling growth of Oenothera biennis L. We prepared buffered suspensions of nα-Fe2O3 and bα-Fe2O3 at 4 levels (0, 0.2, 0.5 and 1 g.L−1). The nα-Fe2O3 increased 89.17% germination percentage, 53.36% germination tolerance index, 82.21% root tolerance index, and 79.42% ferric reducing antioxidant power. The nα-Fe2O3+citrate improved α-Fe2O3 function with a 47% relative hypocotyl length, and 97.32% vigor index2 increase. Leaf area, tolerance index of seedling fresh weight increased at bα-Fe2O3+citrate. Antioxidant enzyme activities are increased in α-Fe2O3+citrate, through which increased biomass and tolerance indices. Oxidative stress control was an important component of this plant’s ability to withstand environmental stress and to succeed in germination and seedling growth. This finding emphasizes that if nα-Fe2O3 were used at low and intermediate concentrations, it would not have toxic effects on this plant, and potentially would result in successful stress tolerance and could act as iron fertilizers for the growth of Oenothera biennis L.

氧化铁纳米粒子(α-Fe2O3)和柠檬酸盐对月见草(Oenthera biennis L.)萌发和氧化系统的协同作用

摘要

本研究的目的是调查铁氧化物纳米颗粒之间的相互作用效应(Nα-的Fe 2 ö 3)和其体积对应物(Bα -铁2 ö 3)有和/或没有发芽柠檬酸盐相互作用和幼苗生长的月见草L.我们制备缓冲悬液Nα-的Fe 2 ö 3和Bα -铁2 ö 3在4个级别(0,0.2,0.5和1 gL的-1)。所述Nα-的Fe 2 ö 3增加89.17%发芽率,53.36%发芽容指数,82.21%根耐受指数,和79.42%铁离子还原抗氧化力。所述Nα-的Fe 2 ö3 +柠檬酸盐改进的α-Fe 2 ö 3具有47%的相对长度的下胚轴功能,和97.32%的活力索引2的增加。叶面积,幼苗鲜重的容指数在Bα -铁增加2 ö 3 +柠檬酸盐。抗氧化酶活性在的α-Fe增加2 ö 3 +柠檬酸盐,通过该增加的生物量和容差指标。氧化胁迫控制是该植物抵抗环境胁迫并成功发芽和幼苗生长的能力的重要组成部分。这一发现强调,如果Nα -铁2 Ø 3以低和中浓度使用,不会对这种植物有毒害作用,并可能导致成功的胁迫耐受性,并可以用作月见草的生长的铁肥。
