THE EFFECT OF CHILLING TEMPERATURE ON GERMINATION AND EARLY GROWTH OF DOMESTIC AND CANADIAN SOYBEAN (Glycine max (L.) Merr.) CULTIVARS
Bibliographic record
Abstract
Low positive temperature, has an inhibiting effect on growth, development and other physiological processes of cold-sensitive plants which include soybean. An experiment in Petri dishes investigated the effect of temperature: 28/28°C (control), 10/28°C, 28/10°C, and 10/10°C (imbibition/germination), on germination of seeds of 8 soybean cultivars. Another experiment, carried out using pot cultures, investigated the response of 2-week soybean plants of the same cultivars to a 6-day chilling period. The following temperatures were used: 25/20°C (control), 25/0°C, 10/0°C (day/night). Both experiments tested the response of 6 domestic soybean cultivars (‘Aldana’, ‘Jutro’, ‘Progres’, ‘Mazowia’, ‘Nawiko’, and ‘Augusta’) and 2 Canadian cultivars (‘OAC Vision’, ‘Dorothea’) to chilling. The obtained results showed that a temperature of 10°C used during germination (28/10°C), and even to a larger extent during imbibition and germination (10/10°C), clearly reduced the speed of germination, percentage of germinated seeds, and radicle length relative to the control, but it increased catalase activity in sprouts. A chilling temperature of 25/0°C and 10/0°C (day/night) significantly increased leaf electrolyte leakage, free proline content and catalase activity relative to the control, but it decreased the photosynthetic rate and total plant leaf area. Seeds and seedlings of cvs. ‘Jutro’ and ‘Nawiko’ were generally the least sensitive to chilling, while ‘Aldana’ and ‘Dorothea’ were the most sensitive.

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.
