Barley and wheat under controlled climatic conditions: A model experiment of vigour and variability
Bibliographic record
Abstract
Two cereal varieties (Bonus spring barley and Drabant spring wheat) were cultivated in the Stockholm phytotron according to standard methods previously described. Bonus is more long-day adapted and more specialized than Drabant, both generatively and vegetatively. Drabant does not reach the maximal level of grain productivity found in Bonus. This variety, however, when compared to Drabant, is characterized by an evident “waste” of vegetative matter for each unit of grain weight produced. Drabant, although lower in maximal yield, shows a higher generative efficiency, especially at shortened day lengths and raised temperatures. Phene variability is rather similar in the two varieties, with some striking exceptions, however. Different degrees of variability are apparently built into the individual traits (phenes) of which the barley plant, or the wheat plant, is composed, reacting in specific ways to the different kinds of phytotron environment.

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.
