Floral development and phenolic compounds production in Agastache rugosa through light regulation.
Article in Planta, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
MAIN
conclusionThe regulation of photoperiod and light intensity significantly affected Agastache rugosa by enhancing growth, modifying flowering dynamics, and promoting the accumulation of key phenolic compounds. Agastache rugosa is a medicinal and aromatic plant valued for its bioactive compounds, which contribute to its application in the flavoring, perfume, and food industries. However, variability in the composition of the bioactive compounds poses challenges for its commercial utilization. Light is a key external signal that regulates plant development and flowering by activating various signaling pathways. This study investigated the effects of extended photoperiods and light intensities on flowering dynamics and phenolic compound accumulation in A. rugosa. The results demonstrated that reduced light intensity promoted vertical growth and biomass accumulation. Furthermore, extended photoperiods significantly enhanced flower productivity and accelerated floral development. Notably, under extended photoperiods with lower light intensity, flowering initiation was delayed; however, subsequent maturation progressed more rapidly, effectively compensating for the initial delay. Extended photoperiod also influenced organ-specific accumulation of phenolic compounds. While high light intensity combined with an extended photoperiod enhanced phenolic compound accumulation in vegetative tissues, lower light intensity under the same conditions led to increased flavonoid accumulation in reproductive tissues. These findings provide valuable insights into the role of light regulation in optimizing both floral productivity and bioactive compound accumulation in A. rugosa, offering potential strategies for its controlled cultivation and industrial application.
