Effects of ploidy level on leaf morphology, stomata, and anatomical structure of Hibiscus syriacus L.
Article in BMC plant biology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundHibiscus syriacus L. is a deciduous shrub with a strong environmental resistance and wide application prospects. The genetic background and ploidy levels of Hibiscus cultivars are complex, and polyploid breeding has long been an important method for developing new Hibiscus cultivars. However, the relationship of ploidy levels with leaf morphology, stomatal characteristics, and leaf anatomy remains unclear.
resultsThis study analyzed three ploidy levels (triploid, tetraploid, and hexaploid) of Hibiscus syriacus. Flow cytometry confirmed the ploidy levels, and morphological traits were evaluated. Leaf length, leaf width, and petiole length decreased with increasing ploidy. Stomatal length, stomatal width, guard cell length, and guard cell width increased and stomatal number and density decreased with increasing ploidy. The hexaploids exhibited the highest midrib diameter and palisade tissue thickness values. Correlation analyses revealed that stomatal morphology served as a reliable marker for determining ploidy levels.
conclusionThis study highlights the impact of varying ploidy levels on the leaf and stomatal morphologies and leaf anatomy of Hibiscus syriacus. These findings can provide theoretical guidance for improving Hibiscus cultivars in terms of stress resistance, adaptability, and ornamental traits, and for developing new cultivars with enhanced characteristics. Future research should focus on utilizing these morphological markers to optimize breeding strategies for Hibiscus cultivars.
