Abscisic acid modulation of drought tolerance and essential oil biosynthesis in Lavandula Coronopifolia Poir.
Article in Scientific reports, 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
Global warming, climate change, and drought are global issues. Thus, drought-tolerant and water-efficient plant species must be chosen. Selection helps maintain crop productivity. Arid-area xerophytic plant Lavandula coronopifolia Poir has little scientific research on its water use and drought tolerance. This study examined the biochemical and phytochemical changes in this plant after ABA treatment and drought stress. Specifically, we analyzed key physiological parameters (relative water content and biomass), biochemical markers (proline content, superoxide dismutase and catalase enzyme activities), and phytochemical components (essential oil composition including monoterpenes and sesquiterpenes). The drought stress treatments were applied at 50-60% and 30-40% of field capacity, while ABA was applied at concentrations of 15 and 30 µM. In low-water conditions, plant biomass and dry weight decreased. However, external ABA application increased RWC, proline, antioxidant response, essential oil percentage, and yield. It reduced drought's negative effects. Additionally, principal component analysis (PCA) found that measured variables explained 88.42% of trait variance. Changes in essential oil composition, including increased oxygenated monoterpenes and sesquiterpene hydrocarbons, were considerable. Significant changes were noticed in linalool (30.76%), decanal (20.90%), linalyl acetate (21.39%), Kessane (11.50%), and Hexadecane (15.91%). These results are indicative of the excellent drought tolerance of L. coronopifolia and ABA-mediated adaptive strategies, and may provide a basis for future applications in agriculture and essential oil production under water-stress conditions.
