Magnetopriming has emerged as a promising seed-priming method, improving seed vigor, plant performance and productivity under both normal and stressed conditions. Various recent reports have demonstrated that improved photosynthesis can lead to higher biomass accumulation and overall crop yield. The major focus of the present review is magnetopriming-based, improved growth parameters, which ultimately favor increased photosynthetic performance. The plants originating from magnetoprimed seeds showed increased plant height, leaf area, fresh weight, thick midrib and minor veins. Similarly, chlorophyll and carotenoid contents, efficiency of PSII, quantum yield of electron transport, stomatal conductance, and activities of carbonic anhydrase (CA), Rubisco and PEP-carboxylase enzymes are enhanced with magnetopriming of the seeds. In addition, a higher fluorescence yield at the J-I-P phase in polyphasic chlorophyll a fluorescence (OJIP) transient curves was observed in plants originating from magnetoprimed seeds. Here, we have presented an overview of available studies supporting the magnetopriming-based improvement of various parameters determining the photosynthetic performance of crop plants, which consequently increases crop yield. Additionally, we suggest the need for more in-depth molecular analysis in the future to shed light upon hidden regulatory mechanisms involved in magnetopriming-based, improved photosynthetic performance.
磁处理已成为一种很有前途的种子引发方法,可在正常和胁迫条件下提高种子活力、植物性能和生产力。最近的各种报告表明,改善光合作用可以导致更高的生物量积累和整体作物产量。本综述的主要重点是基于磁处理的,提高生长参数,这最终有利于提高光合作用性能。源自磁处理种子的植物表现出增加的株高、叶面积、鲜重、中肋厚和小脉。同样,叶绿素和类胡萝卜素含量、PSII 效率、电子传递量子产率、气孔导度以及碳酸酐酶 (CA)、Rubisco 和 PEP-羧化酶的活性在种子的磁处理下得到增强。此外,在多相叶绿素 a 荧光 (OJIP)瞬变曲线中,源自磁处理种子的植物的 J-I-P 相的荧光产量更高。在这里,我们概述了现有的支持基于磁处理的改善各种参数的研究,这些参数决定了作物光合作用性能,从而提高了作物产量。此外,我们建议未来需要进行更深入的分子分析,以揭示基于磁处理的改善光合作用性能所涉及的隐藏调节机制。
