Germination characteristics of <i>Agriophyllum squarrosum</i>
Bibliographic record
Abstract
Agriophyllum squarrosum (L.) Moq. (Chenopodiaceae), a pioneer species of natural succession in semi-arid regions of China, is widely used for vegetation rehabilitation by air seeding. Experiments were conducted to determine the effects of light intensity and photoperiod, as well as constant and alternating temperatures, on germination to improve the technology of air seeding. Seed of A. squarrosum rarely (<18.5%) germinated at 5/15, 10/20, 15/25, and 20/30 °C (night/day); 39.5% of seeds germinated at 25/35 °C in a 14-h (215 µmol·m 2 ·s 1 ) photoperiod. Under dark conditions there was a high final percent seed germination (>90%), except for 71.8% final percent seed germination at 5/15 °C. Constant temperature conditions were associated with lower seed germination (<50%). Less than 13% of seeds germinated at different light intensities (25400 µmol·m 2 ·s 1 ) at 10/20 °C. There was no significant difference in final percent germination when seeds were exposed to 400, 100, or 25 µmol m 2 s 1 for 2 h daily. Final percent germination and germination rate deceased rapidly when the photoperiod was increased under 400 µmol·m 2 ·s 1 . Only 49.2% of seeds germinated after 3 d. Because of the deleterious effect of light on germination, air seeding in late May is recommended.Key words: Agriophyllum squarrosum, air seeding, alternating temperature, constant temperature, light, semi-arid regions.

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.
