Summary: This study evaluated the nutritional qualities of three flower parts (receptacle, stamen, and petal) of 7 different lotuses, including total polyphenol content, flavonol content and constituent, antioxidant activity, and inhibition capacity against alpha-glucosidase. The results showed that the antioxidant activity of each part was correlated with total polyphenol content. The receptacle of 'Yijian Lian' had the highest total polyphenol content, antioxidant activity, and inhibition capacity against alpha-glucosidase. The receptacle of 'Bianlian' had the highest inhibition capacity against alpha-glucosidase. 14 flavonols were identified in all lotus flowers, with the American lotus having the highest levels. This characterization of different lotuses provides valuable insights and resources for the development of food or medicine from lotus flowers.

Summary: The use of near infrared spectroscopy (NIRS) combined with multivariate data analysis was evaluated for the rapid and non-invasive estimation of total polyphenol content (TPC) and antioxidant activity of natural corks. Regression models developed by partial least squares (PLS) regression analysis achieved good performance with high correlation coefficients. The results showed that it is possible to estimate TPC and antioxidant activity of natural corks rapidly and simultaneously by combining NIRS with different multivariate analysis tools.

Summary: This study evaluated the total polyphenolic and flavonoid content of seven Sorbus cultivars, as well as the content of individual phenolic compounds. The antioxidant activity of these cultivars was also measured using different assays. The results showed that 'Granatina' had the highest total phenolic content, mainly contributed by phenolic acids. Flavanols, particularly catechin, were the most abundant flavonoids. 'Businka' had a significant vitamin E content, while 'Alaja Krupnaja' had the highest vitamin C level. These findings highlight the potential health and nutritional benefits of sweet rowanberry and its cultivars.

Summary: The addition of titanium dioxide nanoparticles negatively affected the content, bioaccessibility, and antioxidant activity of polyphenols in apple juice, leading to a decrease in their levels and effectiveness. This suggests that TiO2 NPs may influence the absorption and utilization of polyphenols in the human body.

Summary: This study evaluated the effects of nitrate and ammonium ratios on vegetative growth, mineral uptake, and physiological responses of two semi-vigorous apple rootstocks. It was found that a high NH4+ ratio promoted better vegetative growth, while NO3- treatment increased the concentration of nitrogen, potassium, and calcium in leaves. NH4+ also increased the concentration of phosphorous, magnesium, copper, iron, manganese, and zinc. The highest chlorophyll levels were observed at a 20:80 NO3-:NH4+ ratio, and the highest soluble sugar content was found at an 80:20 ratio.

Summary: Plant hypoxia, caused by soil waterlogging, flooding, or soil compaction, is a major abiotic stress for fruit trees. Extreme weather events associated with climate change are expected to increase the risk of soil waterlogging and flooding in agricultural areas. Fruit trees exhibit various physiological, biochemical, and molecular responses to survive hypoxic conditions in the root zone, and phytohormones play a crucial role in these responses. Cutting-edge technologies, such as engineering of rootstocks and marker-assisted breeding, may aid in developing new rootstocks for low soil oxygen conditions.

Summary: GABA treatment applied as foliar spray at key points of fruit development in pomegranate trees can increase crop yield and improve fruit quality. The highest effects were observed when applying GABA at a concentration of 100 mM, which increased fruit yield and intensified the red colour of the skin and arils. The treatment also increased the concentration of total phenolics and anthocyanins in the fruit.

Summary: Spain is the leading producer of cherimoya, a fruit highly appreciated by consumers. However, it is sensitive to chilling injury, which limits its storage. This study found that melatonin treatment delayed chilling injury and improved the quality of cherimoya fruit during storage. The treatment also delayed the ripening process and maintained fruit quality parameters. Further research is needed to understand the effects of melatonin on gene expression and enzyme activity involved in ethylene production.

Summary: Rainfall during sweet cherry developmental stages can cause preharvest losses due to fruit cracking. Preharvest methyl jasmonate (MeJA) applications effectively reduce fruit cracking and delay ripening on the tree. These MeJA treatments show potential as valuable tools in adapting to climate change and mitigating abiotic stress in sweet cherry.

Summary: This study investigated the effects of glycine betaine (GB) and/or methyl salicylate (MeSA) on the storage quality of 'Moro' blood oranges during cold quarantine storage. The results showed that the combined treatment of 30 mM GB and 100 mu M MeSA significantly reduced weight and firmness losses in the fruit. Additionally, there were changes in titratable acidity (TA), total soluble solids (TSS), TSS/TA ratio, and juice pH across all treatments. Peel color parameters also exhibited characteristic changes, which were delayed by the application of GB and MeSA.
