Impact of reflective groundcover on growth, flowering, yield and fruit quality in Gala apples in New Brunswick
Bibliographic record
Abstract
Privé, J-P., Russell, L. and LeBlanc, A. 2011. Impact of reflective groundcover on growth, flowering, yield and fruit quality in Gala apples in New Brunswick. Can. J. Plant Sci. 91: 765–772. A 5-yr field study was conducted in New Brunswick, Canada, to assess the impact of a reflective groundcover (Extenday TM ) on Gala (Malus× domestica Borkh.) apple trunk cross-sectional area (TCSA), flowering, yield and fruit quality. Overall, a 25% increase in the total number of fruit per tree was realized with use of the 3-m wide reflective groundcover on the orchard floor between tree rows from full-bloom until 3 wk post-harvest; this translated to 26% greater total yield per tree and 16% greater yield efficiency. No overall effects on fruit quality at harvest were associated with use of the reflective groundcover. Trees with reflective groundcover exhibited a greater yearly percentage increase in TCSA (18.5%) than those without (15.0%); neither flowering nor fruit set was affected in any year. These increases in productivity were mediated by the enhanced canopy light environment provided by the reflective groundcover. The primary economic benefit to be derived from use of the Extenday TM reflective groundcover in apple production in the Maritime region is through the capacity to produce higher-yielding crops of fruit on larger trees (increased yield efficiency), without compromising fruit quality. This improvement in production efficiency could translate to an increase in 4.5 t ha −1 of marketable fruit in New Brunswick.

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.
