Abstract

fetched live from OpenAlex

The morphology of fruit and seed as well as the effects of temperature,seeding substrate,GA3and ABA,dehydration,room temperature storage on the seed germination of Ardisia punctata were studied in this paper. The results showed that the 100-grain fresh weight was 6. 34- 6. 95 g,seed moisture content was51. 87%- 52. 97%. The seed could germinate at 15 ℃,20 ℃,25 ℃ and 30 ℃. When the temperature was 25℃ or 30 ℃,the germination rate reached 92%. In sowing depth of 3 cm of loess,vermiculite,palm kernel chaff,perlite,the seedling emergence rate in loess was the highest,followed by palm kernel chaff and perlite,and it was almost 0% in vermiculite. The solutions of 30- 90 mg / L GA3and 10- 60 mg / L ABA had no significant effect on germination of seeds stored for two months at room temperature. The seed moisture content decreased from about 52% to 18% after 1- 3 d silicone dehydration,the germination rate and index decreased to some extent. Storage at room temperature for 3,5 and 12 all reduced the seed germination rate and speed,indicating it was recalcitrant-type seed.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
