Synergistic effects of plant growth regulators and fe₃o₄ nanoparticles on in vitro organogenesis and bioactive compound production in hypericum perforatum.
Article in BMC plant biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This study investigated the combined effects of plant growth regulators (2,4-D and kinetin) and iron oxide nanoparticles (Fe₃O₄-NPs) on in vitro morphogenesis and secondary metabolite production in Hypericum perforatum L. The optimized treatment [2,4-D (0.5 mg/L) + kinetin (2 mg/L) + Fe₃O₄-NPs (4 mg/L)] significantly enhanced growth parameters, showing increases of 59.6% in plant height, 114.0% in root length, and 180.0% in shoot number, as well as a 198.3% increase in callus fresh weight compared with the control. This combination also improved regeneration efficiency (50.85%) and increased hypericin content by 66.6%. GC-MS profiling revealed high levels of hypericin, hyperforin, β-patchoulene, and hexadecanol, accounting for 93.36% of the total peak area, while total phenolic and flavonoid contents increased by up to 80.1%. These findings demonstrate the synergistic role of PGRs and Fe₃O₄-NPs in enhancing both organogenesis and bioactive compound accumulation, providing a promising strategy for the biotechnological improvement of medicinal plants.
