Induction of Phytoalexin Synthesis in Medicago sativa (Lucerne)– Verticillium albo-atrum Interaction
Bibliographic record
Abstract
The first report of a wilt disease of Medicago sativa L. (lucerne, alfalfa) caused by Verticillium albo-atrum was from Sweden in 1918 (Hedlund, 1923), but during the period 1938–1950 the disease was reported in a number of European countries, including Germany (Richter and Klinkowski, 1938), Holland (Hansen and Weber, 1948), and France (Krietlow, 1962). In the United Kingdom, where there had been a large postwar increase in lucerne cultivation, 12,800 hectares in 1942 to 44,000 hectares in 1954, the first recorded outbreak was in 1952 (Noble et al., 1953). Following this first occurrence the disease spread rapidly, resulting in a decline in the area under cultivation to 15,000 hectares by 1970. Subsequently the disease was recorded in Canada in 1964 (Aube and Sackston, 1964) and in Washington State (Graham et al., 1977), and today the disease is of major significance in North America.

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.
