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

backgroundPolyploidization plays a major role in citrus breeding, particularly in generating triploid hybrids through controlled crosses between diploid female and tetraploid male parents. However, limited information is available on how polyploidy affects pollen performance in citrus, and in particular, how temperature influences these processes. In this study, we compared pollen viability under field conditions and pollen tube growth at different temperatures in diploid and tetraploid genotypes, and assessed whether the observed differences were related to genomic instability caused by the tetraploidization treatment.

resultsTetraploid `Clemenules´ and `Fortune´, both colchicine-derived, showed a higher proportion of collapsed pollen grains and reduced viability compared with their diploid counterparts, whereas the spontaneous tetraploid `Pineapple´ displayed values similar to those of the diploid. Pollen tube growth assays revealed slightly faster tube elongation in tetraploids, and notably, self-incompatible diploid pistils of `Fortune´ were successfully fertilized by pollen from its tetraploid form. Genotyping-by-sequencing (GBS) analyses of diploid and tetraploid plants revealed no chromosomal rearrangements or dosage alterations, suggesting that colchicine treatment did not induce large-scale genomic instability.

conclusionsOur findings demonstrate that tetraploidy influences several aspects of citrus pollen performance, while genomic stability remains largely preserved in colchicine-induced genotypes. These results provide new insights into the reproductive biology of citrus polyploids under different temperature scenarios and reinforce the potential use of tetraploid parents in triploid breeding programs.
