| 摘要 | To examine how low-temperature frost affects tea production in the Dabie Mountains by using Lu’an Guapian tea plants as the study material, four groups of temperature treatments were applied in an artificial climate chamber to conduct controlled low-temperature experiments, and measurements of leaf photosynthetic and chlorophyll fluorescence parameters were taken to assess the effects of varying low temperatures on photosynthetic performance and fluorescence characteristics. The results show that all low-temperature conditions cause visible leaf damage, with young leaves exhibiting greater sensitivity than mature leaves, and colder temperatures lead to more severe injury. Low temperatures also reduce photosynthetic capacity and fluorescence indicators, and the magnitude of these effects increases as temperature decreases. These impacts ultimately hinder plant growth and negatively affect tea yield and quality. |
