Cyclic production of sporangia and zoospores by <i>Phytophthora capsici</i> on pepper roots in hydroponic culture
Bibliographic record
Abstract
Production of sporangia and zoospores by Phytophthora capsici on roots of hydroponically grown peppers was shown to be cyclic in nature. Production of sporangia on peppers grown with a 12 h light : 12 h dark photoperiod was mainly diurnal: percentage of full sporangia began to increase between hours 8 and 10 of the dark cycle, the greatest number of full sporangia was present at hours 10–12 of the light cycle, and empty sporangia were most abundant at hours 4–8 of the dark cycle. Zoospore production was primarily nocturnal; populations began to increase at the start of the dark cycle and, in general, peaked sharply at hour 4. Altogether, 79.5% of the zoospores, sampled every 2 h over a 24 h period, were isolated from the hydroponic solution during the dark cycle. Extending the light cycle by 2 h delayed the peak in zoospore production by 2 h, so that it still occurred at hour 4 of the dark cycle. When peppers were grown under continuous light, no cyclic pattern of sporangia and zoospore production occurred. These findings could enhance the success of detection methods and practices for managing zoosporic pathogens in recycled irrigation water.

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.
