1 · What the graph read from it

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.

2 · The registry

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

Drought stress poses a major challenge to sustainable agriculture, and seed priming with melatonin has shown potential to mitigate stress damage in crops. However, the effects of melatonin priming (MP) on drought tolerance in rapeseed (Brassica napus L.) remain underexplored, particularly under field conditions. In this study, two rapeseed cultivars, Shiraali and Pakola, were primed with melatonin and tested under irrigated and drought stress conditions. Results indicated significant cultivar differences for most parameters, except for plant number, peroxidase (POD), catalase (CAT), 1000-seed weight, and harvest index. MP outperformed hydro priming (HP) for most traits, except for branch number, harvest index, and seed protein content. Drought stress significantly affected all parameters, except for POD, branch number, and 1000-seed weight. Shiraali exhibited higher plant density, plant height, chlorophyll a, protein, and erucic acid content, while Pakola showed superior ascorbate peroxidase (APX) and CAT activities, chlorophyll b, carotenoids, oil content, and glucosinolates, as well as higher yield. MP enhanced antioxidant activity and pigment accumulation compared to HP. Under drought conditions, a reduction in plant pigments, yield, and protein content was observed, while oil, glucosinolates, erucic acid content, and antioxidant activities increased. Pakola outperformed Shiraali in 1000-seed weight, yield, and oil content under both irrigated and drought conditions following MP. Our results indicated that melatonin may contribute to drought tolerance through integrated physiological, biochemical, and antioxidant interactions in rapeseed.
