An analysis of Sorghum halepense's behavior in presence of tropane alkaloids from Datura stramonium extracts.
Article in Chemistry Central journal, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
backgroundThis study aimed to quantify the allelopathic potential of Datura stramonium (Jimson weed). Sorghum halepense (Johnsongrass) tolerance was assessed by germinating, seed and growing seedlings, dosing of photo-synthesis pigments, followed by treatment with D. stramonium extract tropane alkaloids.
resultsPreliminary chemical analysis of the extracts showed the presence of alkaloids.The presence of alkaloids was confirmed through HPLC-UV system analysis. Various concentrations of analytic purity alkaloids had similar effects on germination and development of S. halepense's root systems with those of extracts from of D. stramonium. Germination was not affected by any of the tested extracts, but growth was inhibited by the presence of tropane alkaloids. Extracts had effects at higher alkaloid concentrations. Seedlings of S. halepense developed toxicity symptoms in the presence of alkaloid extracts, but the occurrence of several chlorotic and necrotic areas was noticed in the flower extract biotest.
conclusionsResults show that the tested species is sensitive to alkaloids in their growth environment. This research justifies the fact that aqueous extracts from D. stramonium are adequate to the situations in which S. halepense becomes damaging.
