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

High soil salinity constrains global agricultural productivity, necessitating effective mitigation strategies. Plant growth-promoting bacteria (PGPB) offer a promising approach to enhance crop salt tolerance. This study evaluated halotolerant bacteria from O. dillenii to improve tomato (Solanum lycopersicum L.) growth under salinity. Bacteria from plant organs and rhizosphere were screened at 0-3 M NaCl; 52.38% grew above 1.5 M, and six strains-P. flexa S4, S6, R7, C5; B. amyloliquefaciens R4; and M. yunnanensis C11-tolerated up to 2.5 M. Under 120 mM NaCl, biopriming with P. flexa S6 and C5 increased germination to 75% and vigor index by 149.2%. Under 200 mM NaCl, P. flexa S6 boosted root biomass by 167.5%, C5 improved root length and diameter by 25.6% and 30.98%, and R7 enhanced shoot growth while reducing leaf proline by 78%. These selected strains effectively alleviate salt stress and promote tomato growth, promising an application in sustainable agricultural systems.
