Title: Seed Dormancy in Domesticated and Wild Sunflowers (Helianthus annuus L.): Types, Longevity and QTL Discovery
Bibliographic record
Abstract
Elite inbred sunflower (Helianthus annuus L.) lines were found to have short-lived embryo and seed covering dormancies. Seed dormancy of wild sunflowers (H. annuus, H. argophyllus and H. exilis) was found to be controlled primarily by the seed covering (seed coat and pericarp) and embryo dormancy was short-lived (four to eight weeks). Native American Landraces (NALs) had low to moderate embryo and seed covering dormancy, which was more similar to elite lines. The seed covering in the NALs contributed more to seed dormancy than did the seed covering in the elite lines. The seed coat itself was implicated in seed dormancy and the length of dormancy caused by the seed coat varied by accession and variety. Excising of the seed, rather than removing the entire seed covering, increased germination but also increased the number of seed that decayed. Dormancy of embryos from 19 wild sunflower accessions ranging in south to north latitude from Texas to Saskatchewan, Canada was found to be highly variable; however seed covering dormancy was similar among all the wild accessions in the northern latitudes. Germination of accessions in the most southern latitudes was greater (P<0.0001) than germination of accessions from more northern latitudes. The seed

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
