Effects of plant growth regulator (2,4-D) treatments on fruit development and chemical content in the kiwifruit plant (Actinidia chinensis).

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
As a dioecious fruit tree, Kiwifruit requires pollination for female plants to bear fruit. This study used 2,4-Dichlorophenoxyacetic acid (2,4-D), a plant growth regulator, to induce fruit set, improve quality and increase kiwifruit yield in Actinidia chinensis var. 'Donghong' without pollination. Exogenous application of 2,4-dichlorophenoxyacetic acid (2,4-D) effectively triggered parthenocarpic fruit development in 'Donghong' kiwifruit (Actinidia chinensis var. 'Donghong'), while significantly improving fruit quality. The fruit set rate of parthenocarpic fruits reached 16.95% with 2,4-D treatment at 140 days after flowering; female flowers treated with 2,4-D showed differences in pollen structure compared to those treated with water. Also, no viability was detected in female flower pollen treated with 2,4-D. At the maturity stage, the fruits from the 2,4-D treatment were slightly smaller than those from the control group. The 2,4-D treatment group showed significant differences from the control group in skin hardness, flesh firmness and core hardness. There was no significant difference in the soluble solids content between the fruits treated with 2,4-D and those from the control group at maturity. However, the dry matter content of the 2,4-D treated fruits was lower than that of the pollinated fruits. The soluble sugar content of mature fruits from 2,4-D treatment reached 18.59 g/kg, and organic acid content was 18.10 g/kg, resulting in a significantly higher sugar-acid ratio than the control group. The seeds from 2,4-D treated fruits failed to germinate normally. This technology can facilitate the induction of fruit sets in actual production, which has significant practical value and potential in kiwifruit processing. From these results, important data were obtained regarding the establishment and production of kiwifruit orchards without including pollinator varieties, which take up a significant amount of space in the orchard establishment and cause a decrease in the yield obtained from the total area.
