Discovery of a new way of poplar triploids induced with colchicine after pollination.
Bibliographic record
Abstract
Populus alba×P. glandulosa)×P. tomentosa triploids were found from the 107 seedlings,which were obtained from 402 hybrids between P. alba×P. glandulosa etc. (male parent) and P. tomentosa(female parent) by treating the pollinated flowers with colchicine. It indicated that the effective period of inducing triploids with colchicine was 24～36 h after pollination. The highest ratio of obtained triploids reached 57 1%. The growth of triploids also showed obvious superiority over normal diploids. The average stem height and basal diameter of 2 year old triploid seedlings was 29% and 65% larger than the average growth of all the offspring respectively. The growth of BY320 is the best,of which stem height and basal diameter was 55% and 119% higher than the average growth respectively. A new way for inducing poplar triploid was obtained through the present research.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
