Tolerance of lowbush blueberries (<i>Vaccinium angustifolium</i> Ait.) to drought stress. I. Soil water and yield component analysis
Bibliographic record
Abstract
A 2-yr field study examining the effects of drought conditions on the vegetative and reproductive components of the lowbush blueberry (Vaccinium angustifolium Ait.) was completed at the Nova Scotia Wild Blueberry Institute (NSWBI), Debert, NS, in 1998 and 1999. Drought and irrigation treatments were applied over 2 yr in either or both the vegetative and cropping years of production. In general, during the 2-yr study of the vegetative stage, soil moisture levels in the uppermost 0- to 15-cm depth were low (5 to 22%) due to lack of rainfall and increased plant demand. Although berry weight was not affected by drought treatments, berry number was > 50% higher in response to irrigation in both the vegetative and cropping years. From yield component analysis, it was concluded that node number increased at the expense of floral zone length in response to drought-stress. It appeared that the wild blueberry has adapted to partition its resources into vegetative growth under soil moisture limiting conditions, and into reproductive growth when moisture levels are sufficient. Key words: Yield, path analysis, irrigation, drought

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.
