Effects of environmental factors on the phenotypic traits and seed element accumulation of wild Elymus nutans in Tibet.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Soil nutrients and meteorological conditions are pivotal environmental factors influencing plant growth and development. This study systematically analyzes how soil nutrients and meteorological factors influence the phenotypic growth and seed production of wild Elymus nutans in Tibet. These environmental factors are critical ecological determinants, and this research seeks to unveil the complex and diverse ecological adaptation mechanisms of the species. The research encompasses ten counties within the Tibet Autonomous Region, with sampling points distributed across seven distinct ecological environments. By evaluating root soil nutrient levels, collecting meteorological data, and analyzing growth characteristics and seed elemental composition at various sampling points, the study assesses the ecological adaptability of Elymus nutans under diverse soil nutrient and meteorological conditions. Cluster analysis categorized the 25 samples of Elymus nutans into four distinct groups, each exhibiting significant differences in height and leaf length. Correlation analysis revealed a significant negative correlation between sampling point elevation and NH₄⁺, soil total phosphorus, and available phosphorus content, while a significant positive correlation was observed with pH levels. Meteorological variables-including temperature, humidity, and precipitation-significantly influenced plant phenotypes and the elemental composition of seeds. Soil ammonium nitrogen, total phosphorus, and available phosphorus are vital nutrients for the growth of Elymus nutans, and their deficiency has a significant impact on plant phenotypes and overall growth. Environments characterized by high altitude, aridity, and intense radiation constrain plant growth. Climatic conditions influence the growth of Elymus nutans by altering the soil environment, where soil quality plays a critical role in determining growth conditions. These factors interact to collectively impact the ecosystem.
