The influence of the holoparasite Orobanche cumana Wallr. on some morpho-anatomical and physiological-biochemical traits in culture Helianthus annuus L.
Bibliographic record
Abstract
The paper presents results regarding the influence of the angiosperm Orobanche cumana Wallr. on the sunflower harvest and some morpho-anatomical and physiological-biochemical parameters in sunflower hybrids susceptible to broomrape, under different environmental conditions. A negative influence of the parasite was revealed, especially on the background of drought, although under the hydric stress the degree of infestation was significantly lower than in the conditions favorable for crop development. According to the regression analysis, the 71%, 43%, 38%, 42% and, respectively, 30% of variation in sunflower harvest, plant height, leaf area, leaf area index and the amount of chlorophyll a can be explained by the intensity of the attack of broomrape. Strong negative correlations of the mentioned parameters with the incidence of broomrape were found, as follows: r=-0.68; -0.65; -0.66 and -0.59.

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.
