Lipid peroxidation within different amaranth cultivars
Bibliographic record
Abstract
In natural environments, plants are exposed to biotic and abiotic stresses during their whole life circle. Moreover, lipid peroxidation is a physiological indicator of the above stress responses, hence is often used as a biomarker to assess stress-induced cell damage or death. This study evaluated the lipid peroxidation of base and stress leaf discs for nine amaranth cultivars. The feasibility of optical density with λ = 532 and λ = 600 nm was investigated, and the malondialdehyde (MDA) concentration intensity was determined using the TBA method, especially the Thiobarbituric acid (TBA) extinction coefficient to detect its content. Furthermore, MDA values were ranging from 0.007 ± 0.001 mM/g-1 to 0.013 ± 0.002 mM/g-1 and from 0.016 ± 0.002 mM/g-1 to 0.035 ± 0.008 mM/g-1 for base and stress conditions respectively. This study represented high MDA content under water stress and low MDA content detection in leaves of A. caudatus L., A. hypochondriacus L., A. cruentus L., and A. hybridus L. cultivars. This indication defines the better antioxidant activity of these cultivars.

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.
