Nanostructured Calcium Bio-stimulants: A Transformative Approach to In Vitro Plant Regeneration and Metabolite Enrichment

CaNPs or nanostructured calcium as a stimulator is obtaining serious interest due to its capability to stimulate plant growth in controlled ecosystems, and only slight change in cell behavior. There are various nutrient sources that enrich only tissues, but these nanoparticles, along with nourishment, help in initiating a number of responses, starting initial communication while preserving sensitive cell walls. They help direct the critical transition from tissue repair to the formation of new cell masses and then to structured layers. They promote growth and guide these small particles to initiate the internal mechanisms of plants, which are used to generate organic compounds, while removing harmful man-made chemicals in a gentler way. This review provides insights into the functionality of these materials, analyzing their processes and providing important safety guidelines that help in precaution. Ultimately, it indicates that nano calcium could facilitate plant recovery while enhancing the production of natural compounds across various species.
