Abstract

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.

Highlights

IntroductionThe primary function of photosynthesis is to convert light energy into chemical energy, which is the key function in plant life and the food chain for animals, but this can be influenced by many environmental factors
Photosynthesis is the process that makes plants diverse organisms on Earth
It has been suggested that higher OJIP-test parameters, such as Fv/Fm, Fv/Fo, φEo = ETo/ABS, ∆V(IP), PI total and PIABS, in the plants that emerged after SMF treatment contribute to higher light-harvesting efficiency, and as a result, it caused an increase in the biomass accumulation and uptake of CO2 under nonstress and abiotic stresses, such as water, salt, and UV-B stress, thereby enhancing all yield parameters of the crop plants [8,21,22,27,49,50,69]

Summary

Introduction

The primary function of photosynthesis is to convert light energy into chemical energy, which is the key function in plant life and the food chain for animals, but this can be influenced by many environmental factors. Several studies have shown that the photosynthetic process can be affected by high or low light intensity, high or low temperature, heat, salinity, drought, UV-B stress, electrical signals, and geomagnetic field intensity [1,2,3,4,5,6,7,8]. The main can be affected by high or low light intensity, high or low temperature, heat, salinity, drought, UV-B stress, electrical signals, and geomagnetic field intensity [1,2,3,4,5,6,7,8]. The present review aims to present different MF applications and their effects on photosynthetic performance for sustainable agriculture systems
