Abstract: In order to study the physiological mechanisms of the resistance of a new strawberry cultivar ‘Jingyu’ to anthracnose, we used ‘Jingyu’ as research object and high-anthracnose-resistant strawberry ‘Sweet Charlie’, anthracnose-susceptible strawberry ‘Benihoppe’ and ‘Toyonoka’ as controls, to detect the changes of the content of lignin, total phenols, chlorogenic acid and ferulic acid, along with the changes of the activity of phenylalanin ammonialyase (PAL) and polyphenol oxidase (PPO) at the different times in the leaves after inoculated with Colletotrichum gloeosporioides. The results showed that the content or activity of the above physiological factors were improved after inoculated with C. gloeosporioides, and the highest content or activity of these factors in anthracnose-resistant strawberry cultivars were higher than that in anthracnose-susceptible cultivars. These results suggested that the resistance of strawberry ‘Jingyu’ to anthracnose was involved in the high content of lignin, total phenols, chlorogenic acid and ferulic acid, along with the high activity of PAL and PPO. The study laid a foundation for further research on the resistance mechanism of the new strawberry cultivar ‘Jingyu’ to anthracnose.
