Factors affecting germination and emergence of glyphosate-resistant hybrid corn (<i>Zea mays</i> L.) and its progeny
Bibliographic record
Abstract
Laboratory and greenhouse experiments were conducted to compare the effects of agronomic and environmental factors on germination and emergence of glyphosate-resistant (GR) hybrid corn (Mycogen 2G681) and its progeny. The germination of GR hybrid corn and its progeny was 84% to 97% at day/night temperatures of 15/10 °C to 42.5/30 °C, while higher (45/35 °C) and lower (0/0 °C) temperatures reduced germination to ≤6%. Germination was >90% at all alternating as well as constant light and dark periods at a fixed day/night temperature of 30/20 °C. At osmotic stress level of 0 to −0.3 MPa, >90% of hybrid corn and progeny seeds germinated, while osmotic stress level of −0.4 to −1.3 MPa reduced germination to <65%. Greater than 90% germination was observed at a wide range of salt concentrations (0–160 mM), with the lowest germination (53%) at 320 mM. More than 87% cumulative seedling emergence of hybrid corn and its progeny occurred at a depth of 0.5–6 cm and hybrid corn emergence reduced from 86% to 23% compared with 21% to 2% reduction of progeny at 1 and 2 d of flooding, respectively.

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.
