Abstract
Liu, L., Wang, Z., Zhao, X., Nan, L., Nan, H., Wang, S. and Li, H. 2015. Effects of different photorespiration inhibitors on photosynthetic characteristics and berry quality of Vitis amurensis Rupr. Can. J. Plant Sci. 95: 417–426. The effects of two photorespiration inhibitors on photosynthetic characteristics and berry quality of Vitis amurensis Rupr. were studied. The experiments used V. amurensis variety ‘Shuang hong’ as the experimental grape, NaHSO 3 (sodium bisulfite) and isoniazide (INH) as the photorespiration inhibitors with three different spray concentrations, respectively. Results show that both photorespiration inhibitors improved the soluble solids (SS) contents and SS/total acid (TA) ratios (except the 350 mg L −1 INH treatment) in V. amurensis berries; two inhibitors can also improve the concentrations of glucose, sucrose, arabinose, lactose as well as monosaccharides (MS) and MS+disaccharides (DS) contents, and at the same time decrease the TA contents in V. amurensis berries. Meanwhile, all NaHSO 3 treatments had higher SS, SS/TA, glucose, and sucrose than treatments with the same concentrations of INH. However, the arabinose contents in all the INH treatments were higher than those in NaHSO 3 treatments at the same concentrations. Compared with INH treatments, NaHSO 3 were better at increasing net photosythesis rate (Pn), Rubisco carboxylation efficiency (CE), intercellular CO 2 concentration (Ci) and decreasing photorespiration rate (Pr). However, the effects of NaHSO 3 and INH on fluorescent characteristics of V. amurensis leaves were not significant. The fact that maximal values for photochemical efficiency of photosystem II complex (PSII) in the dark (F v /F m ) in this study were large indicate that both NaHSO 3 and INH had positive effects on chlorophyll fluorescence of V. amurensis leaves, which meant they had the ability to release surplus light energy and mitigate photoinhibition by inhibiting photorespiration at all three concentrations. Comprehensive analysis clearly indicates that NaHSO 3 had better effects on photorespiration inhibition and fluorescent characteristics, and improved photosynthesis and the quality of V. amurensis grape berries, especially at 250 mg L −1 .

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.
