Abstract

fetched live from OpenAlex

Pollen grain adhesion, germination and pollen tube gr owth were observed in intergeneric crosses between ten taxa and Ogu CMS.The pol len grains of Crambe abyssinica hardly adhered to the stigma of Og u CMS. Observations made within 48 h showed that the pollen tubes ofRo rippa dubia(Pers.) Hara, Orychophragmus violaceus var. lasiocarpus Migo, Cheriranthus cheiri L.and Crambe abyssisca were obstructed and callose plugs formed in sporo derm at the start of pollen germination. The pollen tubes of Descurainia sophia(L.) Webb. ex Prantl, Matthiola incana(L.) R. Br.and Capsella bursa_pastoris(L.) Medic grew but failed to penetrate the papilla cells. The pollen tubes of Eruca sativa Mill. var. sativa penetrated the papilla cells, but did not penetrate the stigma. The pollen tubes of Brassica campestris ‘Xishuibai’ and Raphanus sat ivus L.var raphanistroides(Makino) Makino entered the stigma ta and styles but did not penetrate the embryo sacs.

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.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
