Cold-induced anthocyanin regulation in horticultural crops: mechanistic basis, trade-offs, and decision-driven temperature management in plant factories.
Review in Horticulture research, 2026. 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
With the expansion of modern horticultural production systems, anthocyanins have attracted increasing attention for their dual role in imparting vibrant coloration and delivering health-promoting benefits. Preharvest temperature management, particularly controlled low-temperature exposure, has emerged as an effective strategy to enhance anthocyanin accumulation in horticultural crops. Despite extensive molecular insights, decision-driven temperature management (DDTM) frameworks that integrate species-, genotype-, and operational parameter-specific strategies for plant factory applications remain lacking. This review addresses this gap by proposing a DDTM-based framework that links molecular regulation to operational protocols for precise anthocyanin enrichment. Evidence is synthesized across diverse horticultural crops representing major production families, including Brassicaceae, Solanaceae, Rosaceae, and other representative horticultural groups, which were selected for their economic importance, high anthocyanin potential, and relevance to human health. Species- and genotype-dependent responses are highlighted, and key operational parameters, including temperature range, exposure duration, and preharvest timing, are analyzed to balance pigmentation intensity, biomass production, and energy efficiency. Plant factories are emphasized as enabling platforms for short-term end-of-cycle cooling and diurnal temperature modulation, which can be integrated with light spectrum management to optimize anthocyanin accumulation while maintaining yield stability. By organizing current knowledge into practical, decision-oriented temperature strategies, this review provides a framework to improve the nutritional quality, compositional consistency, and functional value of anthocyanin-rich crops, supporting horticulture-driven quality assurance and resilient controlled-environment production systems.
