Abstract

fetched live from OpenAlex

N 1939 one of us studied the effect on Alliuni root meristems of I various synthetic phytohormones, among them naphthalene acetic acid. The main histological and cytological effects were briefly described. Special attention was directed to the occurrence of polyploid mitoses in the old cortical tissue. It was demonstrated that the polyploidy in this case was of the endomitotic type, and the inducing factor was thought to be the growth in cellular volume. It could not be decided at that time whether the phytohormoiie caused this chromosome doubling or only acted as a detector of a polyploidy already induced by the natural growth of the cortical cells. After that, spontaneous chromosome doublings of the same type were demonstrated in differentiated tissues of many plants, among them Allium (BERGER and WITKUS, 1946).

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
