Effect of calcium on cyclamen pedicel elongation
Bibliographic record
Abstract
Abstract A greenhouse experiment was conducted to study the effect of calcium (Ca) supply on pedicel growth of Cyclamen persicum “Metis” during flower development. When flower buds started to develop, four foliar spray Ca treatments were applied, including Ca 0 (no added Ca as control), Ca(NO 3 ) 2 , CaEDTA, and CaEDTA+H 3 BO 3 . Calcium spray treatments significantly reduced the number of short pedicels. There were 62% of the flowers with short pedicels ( i.e. , flower height lower than the foliar height) in the control treatment (Ca 0 ). Short pedicels accounted for 23%, 12%, and 10% in the Ca(NO 3 ) 2 ‐, CaEDTA‐, and CaEDTA+H 3 BO 3 ‐treated plants, respectively. CaEDTA was a more effective Ca source than Ca(NO 3 ) 2 for improving cyclamen pedicel elongation and increasing flower numbers. Additional boron (B) supply may have enhanced Ca translocation within the plant. Transmission electron microscopy (TEM) indicated that pedicel‐cell structure was severely damaged in the control plants. Pedicel‐cell damage was greatly alleviated in plants treated with Ca(NO 3 ) 2 . No symptoms of cell damage were found in the CaEDTA‐ and CaEDTA+H 3 BO 3 ‐treated plants. Energy‐dispersive X‐ray spectrometer (EDX) analysis confirmed that CaEDTA+H 3 BO 3 and CaEDTA had increased the Ca : O ratios. Therefore, Ca localization in the pedicel cell had a great influence on the pedicel height of cyclamen, and Ca concentration could be a good indicator for undisturbed cyclamen flower development.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
