EFFECTS OF THREE ROOTSTOCKS ON PHOTOSYNTHESIS, LEAF MINERAL NUTRITION, AND VEGETATIVE GROWTH OF “BC-2 FUJI” APPLE TREES
Bibliographic record
Abstract
Net photosynthesis (Pn), leaf nutrition, and current terminal shoot (CTS) growth of ‘BC-2 Fuji’ apple [Malus sylvestris (L.) Mill var.domestica (Borkh.) Mansf.] trees on three rootstocks, Budagovski (Bud.) 9, Ottawa 3, and M.7 EMLA under field conditions were studied in 1998 and 1999. Rootstock affected the scion leaf Pn, leaf mineral concentrations, and vegetative growth. Leaves of trees on Bud.9 had lower Pn than those on the other rootstocks, and the differences were significant in 1999. Scion leaves on Bud.9 had higher calcium (Ca) and manganese (Mn) but lower potassium (K) concentrations than those on the other rootstocks. Leaves of trees on M.7 EMLA had significantly higher magnesium (Mg), K, and copper (Cu) concentrations than those on the other rootstocks in both years. Trees on Ottawa 3 had significantly lower leaf Cu concentrations than those on the other rootstocks during both 1998 and 1999. Trees on Bud.9 rootstock had shorter limbs and terminal shoots than those on the other rootstocks in 1998 and 1999.

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.
