Intraspecific variation, trait coordination and resource-use strategies of leaf functional traits in Suzhou tea landraces (Camellia sinensis).
Article in BMC plant biology, 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
backgroundUnderstanding intraspecific variation in leaf functional traits is essential for revealing plant resource-use strategies and adaptive mechanisms. Suzhou tea landraces (Camellia sinensis (L.) Kuntze), an important local germplasm resource in eastern China, exhibit substantial variation in leaf functional traits, yet patterns of trait variation and coordination remain poorly understood.
methodsA total of 65 tea landrace strains collected from Suzhou, China, were evaluated for nine quantitative leaf functional traits, including morphological traits (leaf dry matter content, LDMC; specific leaf area, SLA), photosynthetic traits (net photosynthetic rate, Pn; transpiration rate, Tr; stomatal conductance, Gs), and chemical traits (leaf carbon, nitrogen, phosphorus, and potassium contents per unit mass; C
resultsSubstantial intraspecific variation was observed among the tea landraces. SLA exhibited the highest coefficient of variation, indicating strong plasticity, whereas C
conclusionsSuzhou tea landraces exhibit considerable intraspecific variation and coordinated trait relationships, indicating substantial functional differentiation among strains despite their common geographic origin. These findings improve our understanding of functional trait variation in tea plants and provide a theoretical basis for germplasm evaluation, conservation, and cultivar selection.
