Analysis of Taste Quality Differences Between High and Low Grades of Ninghong Tea: From the Perspective of Sensory, Metabolite, and Taste Activity Values.

In this study, the taste quality difference between high (Ninghong-Jinhao tea, JH, unfolded fresh leaves) and low (Ninghong-Congou tea, CG, unfurled fresh leaves) grades of Ninghong tea (unique black tea) was analyzed from the perspective of sensory omics, non-targeted metabolomics, and chemical dose. JH was characterized by sweetness and mellowness with umami, while CG was characterized by sweetness and thickness. A total of 94 differential metabolites contribute to the quality difference between two grades.

Soil Application of Regulates Flavonoid and Alkaloids Biosynthesis in Mulberry Leaves.

Flavonoids and alkaloids are the major active ingredients in mulberry leaves that have outstanding medicinal value. can effectively activate the plants defense response and regulate the plant secondary metabolism. In this study, we explored the effects of soil application of on the content of flavonoids and the most important alkaloids (1-deoxynojirimycin, DNJ) in mulberry leaves.

Device Structure, Light Source Height, and Sunset Time Affect the Light-Trap Catching of Tea Leafhoppers.

Device structure, light source height, and climatic factors can potentially affect the catching of target pests in light traps. In this study, the installation of an anti-escape cover in a newly designed light trap significantly increased the number of catches of tea leafhoppers, , an economically significant pest of tea gardens, and it prevented 97.95% of leafhoppers from escaping.

Untargeted Metabolomics and Transcriptomics Reveal the Mechanism of Metabolite Differences in Spring Tender Shoots of Tea Plants of Different Ages.

The metabolites in the tender shoots of the tea plant are the material basis for the determination of tea quality. The composition and abundance of these metabolites are affected by many key factors, and the tea plant's age is one of them. However, the effect of plant age on the tender shoot metabolites of tea cultivars of different genotypes is poorly understood.
