Metabolism Changes in Tea Plants (Camellia sinensis L.) under Shading Treatment
Metabolomics analysis is a useful technology for comprehensive profiling and comparison of metabolites in biological systems, and it has been extensively used in research of plant metabolism and food science.Metabolomics analysis using NMR,GC-MS and LC-MS platforms has been undertaken in tea.High resolution and high-throughput analysis techniques based on ultra-performance liquid chromatography quadrupole-time of flight mass spectrometry (UPLC-Q-TOF-MS) have been receiving increasing attention and provide unique advantages for metabolomics analysis of teas.In this study, to find the specific differences in metabolism changes caused by covering treatment, the tea plant was covered with two types of shade sails with different characteristic for shading and cooling.Metabolic analysis was performed by UPLC-Q-TOF-MS combined with multivariate statistical analysis.Light intensity and temperature are two major factors that have received particular attention.
