Novel biostimulants-mediate tolerance to drought stress in Phaseolus vulgaris plants by optimizing osmoprotectants and antioxidant defense systems.
Article in Botanical studies, 2025. 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
backgroundDrought stress is a major constraint to the growth and productivity of Phaseolus vulgaris, particularly in dry regions. Utilizing natural biostimulants offers an eco-friendly approach to enhancing drought tolerance by modulating plant physio-biochemical responses. This study investigates the effectiveness of diluted lemon fruit juice (DLFJ) and diluted bee honey (DBH) as foliar biostimulants to mitigate drought-induced stress in P. vulgaris under two irrigation regimes: full (100% ETc) and deficit irrigation (60% ETc).
resultsBoth DLFJ and DBH treatments significantly enhanced photosynthetic efficiency, relative water content (RWC), membrane stability index (MSI), osmoprotectant levels, antioxidant activity, and nutrient accumulation under drought conditions. Among all treatments (4% and 8% DBH, and 3% and 6% DLFJ), DBH-4% was the most effective. It significantly increased chlorophyll and carotenoid contents, photosynthetic efficiency, leaf integrity (RWC and MSI), osmoprotectant levels, antioxidant activities, and green pod yield under 60% ETc compared to untreated controls. It also markedly reduced oxidative stress markers (e.g., malondialdehyde and hydrogen peroxide) and further boosted enzyme activities, including superoxide dismutase, catalase, ascorbate peroxidase, and glutathione reductase.
conclusionsThese findings demonstrate that DBH-4% is a promising and sustainable biostimulant for improving drought resilience in P. vulgaris. Its rich content of antioxidants and osmoprotectants confers significant physiological and agronomic gains under water-limited conditions.
