PROMOTING EARLY FLOWERING IN FLUE-CURED TOBACCO CULTIVARS USING ETRIDIAZOLE AND HIGH-INTENSITY LIGHT—RESPONSE FROM 2 TYPES OF TRAYS
Bibliographic record
Abstract
Breeding for improved varieties that are in line with the market-preferred traits takes many years using traditional breeding methods. Methods that can accelerate the breeding process reduce the time required for cultivar development, release, and commercialization. This study evaluated the effect of tray cell size on the potential for using high-intensity light and etridiazole fungicide (Truban® 25% EC) application as a means of inducing early flowering response in tobacco seedlings for breeding purposes. Tobacco seedlings were grown in expanded polystyrene (Styrofoam) trays of 2 different sizes, which were floated on a solution of etridiazole 20 times the recommended rate of 0.0381 g/L, under high-intensity light (800 W, Fusion Bright 400 Super HPS high-pressure sodium bulb). The results revealed that the tray with larger cell volume, the 128-cell tray, allowed for improved plant growth due to a better root environment giving over 3.5 times more floral initiation and flowering as compared to the tray with small cell size, the 288-cell tray. The large cell tray also provided plants with the better outcome during subsequent seed production. The current study highlights the potential advantages of using this system in accelerated breeding for the successful development and release of pure line cultivars by allowing multiple generations to be achieved within 1 year.

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.
