Abstract

fetched live from OpenAlex

The effect of naphthaleneacetic acid (NAA) and hand thinning on quality and quantity of pear fruit (Pyrus communis L.) cv. Harrow Sweet was investigated in 2005, 2006 and 2007. The experiment included the following treatments: an unsprayed control, hand thinning to 3 fruit cm-2 of trunk cross-sectional area (TCSA), hand thinning to 6 fruit cm-2 of TCSA, NAA at 8 mg L-1 (2005-2007), NAA at 16 mg L-1 (2006-2007) and NAA at 20 mg L-1 (2007). The same treatments were applied to the same trees in each of the three years. NAA thinning did not reduce yield per tree and had no negative effect on fruit set, yield efficiency, or crop load in any of the years. In 2005 and 2006, NAA and hand thinning significantly increased fruit diameter and weight. In 2007, only NAA at 20 mg L-1 significantly increased fruit diameter and weight relative to the control. Fruit firmness was not influenced by NAA or hand thinning in 2005 or 2007, but in 2006, hand-thinned fruits were significantly less firm than control fruit. Hand thinning to 6 fruit cm-2 of TCSA increased fruit soluble solids content in 2006 and 2007. Neither NAA nor hand thinning influenced total sugars or organic acids in fruit.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
