Spectral Behavior of Pinus elliottii, Subjected to Drought in Southern Brazil
Bibliographic record
Abstract
The second most cultivated plant to a forest range in Brazil is the Pinus elliottii. This paper aims to evaluate the spectral behavior of individuals of Pinus elliottii in the electromagnetic radiation (1st) of the visible and (2nd) the infrared, when submitted to the water deficit. The experiment was conducted in the city of Santa Maria located at the Rio Grande do Sul State. The spectral responses of 10 individuals of Pinus elliottii were observed in different climatic seasons at 24 months of age. To evaluate the spectral behavior a spectroradiometer was used, and the behavior in the 450 to 1700 nm range was analyzed. Five individuals were submitted to water deficit treatment and five were used as controls, remaining in adequate water conditions. The spectral pattern for individuals submitted to water deficit was similar, but a trend of wavelength responses in the region of visible green (577-491 nm) and near-infrared (1100-789 nm) was noticeable. The most evident differences occurred in the fall season when differences in spectral amplitudes are noticeable and significantly different from the rest of the year.

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.
