Evaluation of cytokinin types and LED light spectra for enhanced production of diarylheptanoids in Alnus incana subsp. incana.

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
This study aimed to develop an efficient in vitro propagation system for Alnus incana subsp. incana that enables both vigorous shoot proliferation and enhanced production of bioactive diarylheptanoids. Among the tested cytokinins, 5 µM 6-benzylaminopurine (BA) was most effective for promoting shoot proliferation(1.311 ± 0.070), whereas 10 µM zeatin moderately induced shoots but significantly increased secondary metabolites, with oregonin being 1.82-fold, hirsutenone 1.39-fold, and hirsutanonol 1.25-fold higher than BA 5 µM treatment. In terms of light quality, blue LED irradiation (450 nm) led to the highest antioxidant activity, with 2,2-diphenyl-1-picrylhydrazyl(DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)(ABTS) radical scavenging values of 48.67 ± 27.33% and 92.78 ± 0.35%, respectively. In contrast, white LED (broad-spectrum) supported both balanced growth (1.133 ± 0.051 shoots per explant under 10 µM zeatin) and elevated metabolite production, including oregonin (108.089 µM) and hirsutanonol (13.203 µM). The combination of 10 µM zeatin and white LED thus provided an optimal compromise between shoot proliferation and secondary metabolite accumulation, offering a sustainable strategy for producing antioxidant-rich A. incana plantlets in vitro.
