Evaluation of cold tolerance in sorghum germplasm from the Chishui River Basin in China: insights from germination, field trials, and physiological assays.

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
Introduction: Exploring cold-tolerant sorghum germplasm is crucial for improving production in low-temperatures regions. However, the cold tolerance of local sorghum germplasms in the Chishui River Basin, located in the southwestern China, remains poorly characterized. Methods: We evaluated 71 sorghum germplasms at Maotai Institute from 2022 to 2024 using germination tests, pot trials, and field experiments with a two-factor design. Germination potential, germination percentage, and seedling vigor traits (plumule and radicle length and weight) varied significantly among the 71 sorghum germplasm ( Results: Cluster analysis classified these into four groups: cold-tolerant (11), moderately cold-tolerant (22), moderately cold-sensitive (29), and cold-sensitive (9). Agronomic data collected under two early sowing conditions (severe and mild low-temperature stress) demonstrated that several germplasm accessions, like No. 12, maintained high emergence rates (97% and 100% Conclusion: This study not only identifies valuable cold-tolerant sorghum germplasms but also elucidates their physiological mechanisms, providing essential insights and materials for developing cold-tolerant varieties and resilient cultivation practices in the Chishui River Basin.
