Photosynthetic variation for climate-resilient crops: photosynthetic responses to fluctuating light and chilling in tomato.
Article in Physiologia plantarum. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
An increase in global demand for crop-based products necessitates an increased crop yield. Optimizing photosynthesis, which is sensitive to environmental fluctuations, offers a promising strategy to improve crop yield and resilience. Photosynthetic responses often lag behind changes in irradiance, resulting in the loss of potential carbon gain. Additionally, global warming is accompanied by unexpected chilling spells, further affecting photosynthesis. Thus, developing chilling-resilient crops and optimizing photosynthetic responses to fluctuating light is critical. This can be achieved by identifying genetic markers associated with desirable photosynthetic traits in plant populations. However, the combined effect of chilling and photosynthetic responses to fluctuating light remains unexplored, and there is a lack in populations designed to explore these responses. Thus, exploration needs to be done in pre-existing populations where there is phenotypic variation in photosynthetic responses and in how chilling affects these responses within parental lines. This study examined the variation in photosynthetic responses of the parental lines of a Multi-parent-Advanced-Generation Inter-Cross (MAGIC) population of tomato (Solanum lycopersicum) under fluctuating light and suboptimal temperatures. Photosynthetic responses to step increases and step decreases in irradiance were measured using modulated chlorophyll fluorescence and the effect of lowered temperature (14°C) on these responses was investigated. The results showed variation in the kinetics of the response of quantum efficiency of PSII (Φ
