Abstract

Salinity stress is one of the environmental factors that has many negative effects on the biochemical and physiological processes of the plants. In addition, according to previous reports, nanoparticles have both negative and positive effects on different plant species. The present research evaluated the interaction effects of zinc oxide (ZnO) nanoparticles and salinity stress on two cultivars of Trigonella foenum-graecum. To this end, four levels of salinity and three levels of ZnO nanoparticles were used, followed by measuring some biochemical parameters, trigonelline, antioxidant enzymes, and some elements such as Na, K, Ca, Zn, and Fe. Based on the results, increasing salinity concentration led to a significant increase in proline and malondialdehyde in both cultivars and significantly increased protein while reducing sugar in cv. Mashhadian. At a high concentration of salinity, polyphenol oxidase, peroxidase, lipoxygenase, and phenylalanine ammonia lyase significantly increased in both cultivars. In addition, an increase in salinity concentration increased Na concentration, while it decreased K and Ca concentrations in the shoot and root in both cultivars. Overall, the interaction effects of nanoparticles and salinity stress varied due to different salinity and nanoparticle concentrations, as well as the cultivar type.

摘要

盐分胁迫是对植物的生化和生理过程产生许多负面影响的环境因素之一。另外，根据先前的报道，纳米颗粒对不同植物物种既有正面影响又有正面影响。本研究评估了氧化锌（ZnO）纳米颗粒和盐分胁迫对两个品种的夏枯草的影响。为此，使用了四个水平的盐度和三个水平的ZnO纳米颗粒，然后测量一些生化参数，铁线果碱，抗氧化酶以及一些元素，如Na，K，Ca，Zn和Fe。根据结果​​，盐度浓度的增加导致两个品种中脯氨酸和丙二醛的显着增加，蛋白质含量显着增加，同时降低简历中的糖分。Mashhadian。在高盐度下，两个品种的多酚氧化酶，过氧化物酶，脂氧合酶和苯丙氨酸氨裂合酶均显着增加。另外，盐度浓度的增加增加了Na的浓度，而同时降低了两个品种的芽和根中的K和Ca浓度。总体，
