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

Breaking of apical dominance by removing the shoot apex initiates competition between the remaining buds to assume the dominant position. Cotyledonary buds located closest to the stored photoassimilates also participate in this race, as was demonstrated a century ago in a pea model. Using pea (Pisum sativum L.) plantlets we showed that sucrose feeding through the stem stump enhances the outgrowth rate of initiated buds. However, this cannot overwrite the axillary bud competition pattern, during which the upper axillary bud outcompetes all the lower buds. Further, disruption of polar auxin flow by stem wounding triggers cotyledonary bud outgrowth regardless of assimilates supplied by the cotyledons. Similarly, replacement of the cotyledons with a sucrose-containing gel did not influence the cotyledonary bud outgrowth scheme, whilst in contrary, an auxin-containing gel did. Using PIN1 immunolocalization assay, we demonstrated that the cotyledonary buds are located at a confluence of two auxin flows originating from the apex and the cotyledons. Formation of a PIN1-labelled auxin channel leading to the stem polar auxin flow is a prerequisite for cotyledonary bud outgrowth.
