Modulating grapevine performance and hormonal dynamics under summer stress by the synergistic effects of kaolin and silicon.
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 7 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: Climate change is intensifying heat and drought stress in viticulture, negatively impacting yield and grape quality. High temperatures accelerate sugar accumulation and reduce organic acids, disrupting wine balance. Drought also lowers grapevine resilience by reducing stomatal conductance and photosynthetic efficiency, highlighting the need for sustainable strategies. This study evaluated the effects of foliar applications of kaolin (Kl) and silicon (Si) mixtures on grapevine physiology and fruit quality under summer stress. Methods: The experiment was conducted over two seasons (2023-2024) in a commercial vineyard (Quinta de Ventozelo, Douro Region) using the Touriga Franca variety. Treatments included a control and four formulations (MiKS 1 to 4), all with 2% Kl and Si ranging from 2% to 8%. Physiological measurements included gas exchange, chlorophyll a fluorescence, and leaf water potential. Biochemical analyses assessed pigments, sugars, proteins, phenols, flavonoids, Results: Si and Kl treatments, particularly MiKS 3 and MiKS 4, significantly enhanced gas exchange parameters, water potential, and chlorophyll fluorescence under high-stress conditions. These treatments also increased chlorophyll, carotenoids, cuticular waxes, and cuticle thickness, contributing to improved plant vitality and stress resilience. Secondary metabolites such as Discussion: Overall, Si and Kl mixtures effectively mitigated summer stress, improving grapevine physiological, biochemical, and anatomical responses under challenging climate conditions.
