Effects of growth years on the quality of cultivated
Article in Frontiers in plant science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Introduction: With the rapid decline in wild Bupleurum scorzonerifolium (BSW) resources, large-scale planting of cultivated B. scorzonerifolium (BSC) has begun. However, the effects of growth years on the quality of BSC, as well as the quality difference between BSC and BSW remain unclear. Methods: This study utilized trait characteristics, microstructure, cell wall components, sugar components, main pharmacological substances, metabolomics, and transcriptomics as key indicators and techniques, to comprehensively characterize and investigate the molecular mechanisms underlying the quality differences between BSC of different growth ages (1-3 years) and between BSC and BSW. Results and discussion: As the growth years increased, the root weight of BSC continuously increased, accompanied by root head expansion. Root length and middle and lower section diameters showed significant increases from 1 to 2 years, stabilizing from 2 to 3 years. The ratio of phloem width to xylem radius, along with the contents of total saponins and saikosaponins a, b2, c, and d, exhibited a trend of initial decrease, followed by an increase. Additionally, the number and size of oil cavities and ducts, as well as the volatile oil content, continuously increased. Metabolomic and transcriptomic analyses identified saponins and terpenoids as the primary differential components between different BSC growth years, with genes Bchns02G071080 and Bchns05G031860 (saponins) and Bchns01G03800 (terpenoids) identified as potential key regulatory genes. Furthermore, compared to the long-established, high-quality BSW, 3-year-old BSC (BSC3) showed the closest resemblance in morphological traits, microstructure, and chemical component content, particularly for key pharmacological substances, such as volatile oil, total saponins, and saikosaponins a, b2, c, and d. Considering both quality and economic benefits, BSC3 is recommended as a substitute for BSW. To the best of our knowledge, this is the first study to report the effects of growth years on the quality of BSC, offering valuable insights for guiding the artificial cultivation and quality assurance of B. scorzonerifolium.
