摘要
Cinnamomum burmannii (Lauraceae), native to Southeast Asia and Indonesia (Elliott and Brimacombe 1987), is a subtropical, green, broad-leaved and widely distributed species. It is highly adaptive to different environmental stresses, a feature that is important for its use in the vegetative restoration of degraded ecosystems (Sun et al. 2005). It is famous as an ornamental, horticultural and air-purifying plant in South Asia (Huang et al. 2011). It is also used as spice (Zhang et al. 2008), in food supplements and flavourings (Wang et al. 2013), and as a natural food preservative, due to the bioactive components in cinnamon sticks (Shan et al. 2007). Furthermore, a report showed a potential use of its methanol extract, transcinnamaldehyde, for the treatment of nasopharyngeal carcinoma (Ahmad et al. 2013). Therefore, C. burmannii has great ecological and sociological values. The expansion of C. burmannii plantations in recent years has resulted in pest and disease problems that are becoming a serious concern (Li 2007; Zhang et al. 2008). Common pathogens include Exobasidium sawadae Yamada causing powdered fruit disease, Phyllosticta cirsii Desm. causing leaf spot and Cephaleuros virescens Kunze causing algal spot (Cen and Su 2003). However, leaf spot symptoms were complex, and the causal agents clearly included more than one species. To distinguish the complex of pathogens causing leaf spots and to improve methods for the management of these diseases, a detailed investigation of the symptoms and the causal agents was undertaken.
