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

backgroundOrchids maintain a symbiotic relationship with mycorrhizal fungi in the lifecycle. Previous reports indicated that diverse mycobionts may have different roles during orchid growth and development. Although various mycorrhizal fungi have been isolated from Dendrobium roots and protocorms, little is known about their specific effects on seed germination and seedling growth. To understand the specific role of isolated fungal strains (i.e., Tulasnella and Sebacina), we used symbiotic culture to compare the effect of 6 fungal strains on seed germination and seedling growth of Dendrobium officinale, an important Chinese medicinal orchid.

resultsIn symbiotic germination tests, 6 fungal strains (4 Tulasnella strains and 2 Sebacina strains) promoted seed germination with different efficiencies. Seeds inoculated with Tulasnella strains S6 and S7 conferred higher germination percentage and faster protocorm development than other fungal strains. In symbiotic cultures, seedlings inoculated with Sebacina strain S3 had optimal fresh and dry matter yield. Also, Tulasnella strains S6 and S7 promoted seedling growth with good fresh and dry matter yield. Sebacina strain S2 inoculation greatly enhanced root and tiller production and the content of total crude polysaccharides, although seedlings were smaller with less fresh and dry matter yield than other seedlings.

conclusionsTulasnella and Sebacina strains could promote seed germination and seedling growth of D. officinale with different efficiencies. Our results suggest a non-specific mycorrhizal association and development-dependent preference. Our data provide the basic knowledge for use of different fungal strains in conservation and/or production practices of D. officinale.
