The swelling agent is a plant growth regulator that alters the composition and content of nutrients and volatile gases in the fruit. To identify whether grape fruit had been treated with swelling agent, the odor information and quality indexes of grape berries treated with different concentrations of swelling agent were examined by using electronic nose technology and traditional methods. The contents of soluble sugars, soluble solids, soluble proteins and vitamin C were significantly increased in N-(2-chloro-4-pyridyl)-N’-phenylurea (CPPU) treated fruit. The contents of hexanal, (E)-2-hexenal, and nonanal aldehydes decreased significantly. Similarly, the levels of phenyl ethanol, 1-octanol, ethanol, and ethyl acetate alcohols and esters also decreased noticeably. Additionally, the levels of damascenone, linalool, and geraniol ketones and terpenoids decreased. However, the contents of benzaldehyde, D-limonene, acetic acid and hexanoic acid increased. In addition, the electrical signals generated by the electronic nose (e-nose) were analyzed by linear discriminant analysis (LDA), support vector machine (SVM) and random forest (RF). The average recognition rate of SVM was 94.4%. The results showed that electronic nose technology can be used to detect whether grapes have been treated with swelling agent, and it is an economical and efficient detection method.

Sugar–acid metabolism is a key factor in determining grape quality, and gluconeogenesis is one of the important sugar–acid metabolic pathways. To explore the effects of reduced light intensity on grape berry quality and gluconeogenesis under greenhouse cultivation, we used the ‘Shine Muscat’ cultivar. With decreasing light intensity, the photosynthetic activity in the grape leaves decreased, resulting in significant reductions in the net photosynthetic rate, transpiration intensity, and stomatal conductance while reducing organic matter accumulation, thus significantly affecting subsequent grape berry quality and gluconeogenesis. Shade treatment inhibited the accumulation of glucose, fructose, and soluble solids in the grape berries but promoted the accumulation of malic acid, tartaric acid, and citric acid. PEPCK and FBP are the key genes underlying the effect of light intensity on gluconeogenesis in grape berries, with PEPCK being involved mainly in tartaric acid metabolism and FBP being involved in malic acid, citric acid, and tartaric acid metabolism.
