Powdery-Fruit Disease of Cinnamomum burmannii and its Influence on Fruit Essential Oil

摘要

Powdery-fruit disease is a notorious disease of Cinnamomum burmannii, causing severe loss to fruit production. In this study, the pathogen causing powdery-fruit disease of C. burmannii was identified based on morphological characters and 18S rDNA gene sequences. Three essential oils samples from the leaves and normal and infected fruits of C. burmannii were obtained by hydro-distillation and analyzed by GC-MS. The composition of the infected fruits was strongly affected by the pathogen of powdery-fruit disease. This study provides new knowledge for the change in chemicals before and after pathogen infection in the fruits of C. burmannii, paving the way to further reveal the unknown mechanism of pathogen infection in C. burmannii.
