- 摘要：
- Previous reports have shown that oligosaccharins could regulate the defense responses in plants. However, the application of oligosaccharins in tea plantations to resist the invasion of diseases is largely unknown. In this study, we tested the control efficiency of oligosaccharins against the disease Phyllosticta fheaefolia in the tea plantations in Guizhou, China. Then, we detected the tea quality effect by oligosaccharins. The results showed that the control efficiency of oligosaccharins to P. fheaefolia was 47.37% (3 days, 2018), 52.43% (3 days, 2019), 48.20% (7 days, 2018) and 55.57% (7 days, 2019). After 1 month, the contents of moisture (P < 0.05, 2018, 2019), polyphenol (P < 0.01, 2018, 2019), and amino acid (P < 0.05, 2018) in the oligosaccharins region was significantly higher than those in the control region. Thus, oligosaccharins can promote the tea plant to resist the invasion of P. fheaefolia and improve the quality of tea in Chinese tea plantations.
