Changes on Potato Leaf Metabolism and Anatomy Induced by Plant Growth Regulators
Bibliographic record
Abstract
The use of growth regulators in potato crop is an alternative to reduce the aerial growth of plants and redirects carbon assimilates and nutrients to the tubers. Therefore, the objective of this study was to evaluate the effects of growth regulators, paclobutrazol and trinexapac-ethyl on plant growth and changes on the anatomy of leaves of cultivar Markies in summer conditions of the southern region of Brazil. Potato plants cv. Markies were in the summer growing season of Southeast region of Brazil and 35 days after planting, the plants were sprayed with paclobutrazol (PBZ) at 0.125 and 0.250 L ha-1 and trinexapac-ethyl (TE) at 1.0 and 2.0 L ha-1. Treatment with PBZ at both doses reduced the height of potato plants, which resulted in higher index of leaf chlorophyll and reduced the content of starch and non-reducing sugars. Both PBZ and TE treated plants exhibited anatomical changes in the leaves, including larger epidermal cells and more elongated palisades cells. These data suggest that such changes in the anatomy of potato leaf in response to the use of PBZ directly influence leaf metabolism.

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.
