Study of Some Characteristics Related to the Sexual Reproduction in Autotetraploid Vicia narbonensis
Bibliographic record
Abstract
Some parameters such as frequency of pod formation, average number of seeds per pod and percentage of emptypods were used to evaluate the variation of fertility in autotetraploid Vicia narbonensis. The results showed thatthe autotetraploid and diploid parents had the same number of ova per gynaecium. However, the tetraploidseedling produced fewer seeds per pod and per seedling than their corresponding diploids; the poor fertilizationof many ovum was probably behind the decline of fertility in the autotetraploids. Several factors may beinvolved: the low efficiency of diploid pollen (related to a relatively slow growth of the pollen tubes), anunbalanced meiosis for a great number of mother cells of pollen grains and a significant morphologicalmodification of the reproductive system due to the passage from the diploid to the tetraploid state.

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.
