Abstract

Nanoparticle applications have recently become a popular method due to increase the tolerance levels of plants to environmental stresses. In this study, changes induced by exogenous application of green synthesized and commercially purchased zinc oxide nanoparticles (ZnO NPs) (100, 500, 1000 mg/L) to drought-stressed Capsicum annuum plants were studied through comprehensive morphologic, anatomic, physiological and biochemical analyzes. While drought decreased relative water content (RWC) and leaf water potential (LWP), it increased proline, thiobarbituric acid reactive substances (TBARS) content and antioxidant enzyme activities. Exogenous ZnO NPs increased RWC and LWP but they decreased TBARS and proline contents in drought-stressed plants. Furthermore, the data obtained in this study revealed that the response of the antioxidant enzyme varies depending on the concentration of the nanoparticles and the type of synthesis. However, green synthesized ZnO NPs applications (100 and 500 mg/L) were found to be much more effective in reducing the adverse effects of drought stress than those synthesized chemically. The results of this study indicated that although the response of Capsicum annuum plants to ZnO NPs applications varied according to the type and concentration under drought conditions, nanoparticle applications did not lead to a consistent stress response.

绿色和化学合成氧化锌纳米粒子对干旱胁迫下辣椒的影响

纳米颗粒的应用最近成为一种流行的方法，因为它可以提高植物对环境胁迫的耐受性。本研究通过对绿色合成氧化锌纳米粒子（ZnO NPs）（100、500、1000 mg/L）外源施用对干旱胁迫下辣椒植株的形态、解剖、生理和生化等方面的综合分析，研究了氧化锌纳米粒子（ZnO NPs）对干旱胁迫下辣椒植株的影响。干旱降低了植株相对含水量（RWC）和叶片水势（LWP），提高了脯氨酸、硫代巴比妥酸活性物质（TBARS）含量和抗氧化酶活性。外源ZnO NPs增加了干旱胁迫植株的RWC和LWP，但降低了TBARS和脯氨酸含量。此外，本研究获得的数据表明，抗氧化酶的反应取决于纳米颗粒的浓度和合成类型。然而，绿色合成ZnO NPs（100和500 mg/L）比化学合成ZnO NPs更有效地减少干旱胁迫的不利影响。研究结果表明，在干旱条件下，尽管不同类型和浓度的氧化锌NPs对辣椒植株的胁迫响应不同，但纳米颗粒的施用并没有导致一致的胁迫响应。
