褐皮病简称死皮,现已成为多数植胶国橡胶园的一个严重问题。虽然一些人称之为病害,但迄今为止尚未发现与褐皮病有关的病毒或真菌一类的病原体(Liyanage等,1982)。人们更普遍地认为是胶树树皮生理失凋。 Brown skin disease referred to as dead skin, rubber plantation has now become the majority of rubber planting a serious problem. Although some call it a disease, so far no pathogens such as viruses or fungi associated with the disease have been found (Liyanage et al., 1982). It is more commonly thought of as the physiological loss of the bark of gum trees.
