Physiological and ecological response of Cinnamomum camphora under drought stress.
Article in BMC plant biology, 2025. 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
The study focused on one-year-old Cinnamomum camphora seedlings and set up three stress environments: drought, waterlogging, and drought rehydration. The physiological and ecological responses of Cinnamomum camphora under different stress conditions were comprehensively analyzed using methods such as biomass measurement, gas exchange parameters (including net photosynthetic rate, stomatal conductance, transpiration rate), stable carbon isotope ratios, and analysis of non structural carbohydrate content. The results showed that drought stress significantly reduced the total biomass of Cinnamomum camphora (23.57 ± 0.56 g, compared to the control group of 40.84 ± 0.61 g), especially the leaf biomass (4.30 ± 0.45 g), which was 59.28% lower than the control group. The root biomass of the waterlogging stress group was 8.86 ± 1.15 g, which was 38.51% lower than the control group. Stable carbon isotope analysis showed that under drought stress, the δ 13 C value of Cinnamomum camphora significantly increased (-26.7‰), indicating that plants improve water use efficiency by closing stomata; The waterlogging stress reduced the δ 13 C value (-29.1‰), indicating limited photosynthetic efficiency. The rehydration experiment showed that the leaf water potential quickly recovered after rehydration, and the photosynthetic parameters (such as photosynthetic rate and stomatal conductance) gradually increased, demonstrating good drought tolerance. Compared with previous studies on single stress or a single organ, this study analyzed the effects of drought, waterlogging, and rehydration stress on the biomass of different organs in Cinnamomum camphora, revealing the resource allocation strategies and physiological adaptation mechanisms of Cinnamomum camphora under different stresses. This study provides a scientific basis for the adaptive management of Cinnamomum camphora in ecological restoration and urban greening.
