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
