Abstract

Growth of plants, apart from being complex and highly dynamic, is directly dependent on the environmental conditions, particularly the quality of soil for terrestrial plants and the water quality for aquatic plants. Presence of microplastics in the environment may affect the plant growth in numerous ways depending on the contents of the growing medium. However, increasing presence of microplastics at an alarming rate due to its pervasive usage and mismanagement of plastics have led to significant environmental problems. Several research studies have been conducted as well as reviewed to investigate the toxic effects of microplastics on aquatic systems, but studies that investigate the toxic effect of microplastics on the terrestrial systems are limited. Hence, in this review the individual and the combined effects of microplastics on the growth of plants and seed germination in both aquatic and terrestrial ecosystems are concisely discussed. At the beginning accumulation of microplastics on aquatic and terrestrial ecosystem is discussed and the reasonable solutions are highlighted that can mitigate the effects from the widespread increase of the plastic debris. Thereafter, the individual and combined effect of microplastics on seed germination and plant growth is reviewed separately while summarizing the important aspects and future perspectives. This review will provide an insight into the existing gap in the current research works and thus could offer possible implications on the effect of microplastics on plant growth and seed germination in aquatic and terrestrial ecosystem. ==========================================================================================COPYRIGHTS©2021 The author(s).

微塑料对水生和陆生生态系统中植物生长和种子萌发的影响
植物的生长除了复杂和高度动态外,还直接依赖于环境条件,特别是陆生植物的土壤质量和水生植物的水质。环境中微塑料的存在可能以多种方式影响植物生长,这取决于生长介质的含量。然而,由于塑料的普遍使用和管理不善,微塑料以惊人的速度增加,导致了严重的环境问题。为了调查微塑料对水生系统的毒性影响,已经进行了几项研究并进行了审查,但调查微塑料对陆地系统毒性影响的研究有限。因此,本文简要讨论了微塑料对水生和陆地生态系统中植物生长和种子萌发的单独和联合影响。本文首先讨论了微塑料在水生和陆地生态系统中的积累,并提出了合理的解决方案,以减轻塑料碎片的广泛增加对水生和陆地生态系统的影响。在此基础上,分别综述了微塑料对种子萌发和植物生长的单独和联合影响,并总结了其研究的重点和未来发展方向。本文综述了微塑料在水生和陆地生态系统中对植物生长和种子萌发的影响,并对目前研究工作的空白进行了深入分析。========================================================================================== 版权©2021年作者(年代)。这是一篇根据知识共享署名协议(CC BY 4.0)发布的开放获取文章,该协议允许在任何媒体上不受限制地使用、分发和复制,只要引用原作者和来源。不需要许可从作者和出版商 .==========================================================================================
