Low Temperature Storage and in vitro Pollen Germination of Selected Spring Wheat Accessions
Bibliographic record
Abstract
The study was conducted to evaluate in vitro pollen germination of 50 spring wheat (Triticum aestivum L.) accessions at three storage temperatures (23 °C, 5 °C, and -20 °C). Germination of the mature pollen was measured right after harvest (0 time), and 24, 48, and 72 h after storage (HAS). Differences in fresh pollen germination between accessions were significant and ranged from 21.15% to 1.09%. Pollen germination was the lowest at 24 h at room temperature. The pollens of 24 wheat accessions (AAC Scotia, AW636, AW725, AW780, AW804, AW822, AW823, Brookfield, BRS Pardela, ECSW05, ECSW38, ECSW48, ECSW49, ECSW69, Hoffman, Kleos, Major, Nass, 12NQW-237, 12NQW-413, 12NQW-414, 12NQW-436, 12NQW-754, and 12BW0374) were viable after 24 h when they were stored at 5 °C. Sub-zero temperature did not prolong pollen viability.

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.
