1 · What the graph read from it

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.

2 · The registry

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

The effect of high-voltage electrostatic field (HVEF) on maize seeds' resistance to chilling injury remains unclear. This study investigates the chemical and spatial changes induced by HVEF at macroscopic and microscopic levels via the combination of physiological assessments and scanning electron microscopy (SEM). Maize samples were categorized into low and normal-temperature groups. At an HVEF strength of 1.6 kV/cm, all indices in the low-temperature group significantly improved relative to the control (P < 0.01), with germination potential, rate, index, and vigor index increasing by 11.7%, 11.2%, 10.5%, and 31.7%, respectively. Root length, shoot length, and dry weight of maize seedlings rose by 20.3%, 19.2%, and 16.6%. Further analysis revealed a 62.7% increase in soluble sugar content in HVEF-treated seeds and the lowest leaching solution conductivity of 1.6 kV/cm. These results demonstrate that HVEF treatment enhances soluble sugar accumulation during seed germination, regulating osmotic balance within the cells. Furthermore, SEM assessed maize microtissue morphology after chilling injury and HVEF treatment. Optimal HVEF treatment resulted in cell wall expansion, enhanced fiber elasticity, reduced interstitial spaces, and swollen cells, indicating improved hydrophilicity and protease activity. This study offers valuable insights into the mechanisms by which HVEF improves seed performance under low-temperature stress.
