摘要

Stem bleeding of coconut was discovered in 2009 in Hainan, China. Affected trunk areas exhibited dark discoloration and a reddish brown or rust-colored liquid bleeding from different points. Stem tissues under the lesions rotted and became brownish yellow to black. Affected plants died within 3 to 4 months after stem symptoms first appeared. Stem bleeding of coconut is known to occur in production areas worldwide. The disease was first reported in Sri Lanka (1), caused severe damage to PB-121 hybrids in Indonesia (2), and is now known to occur in many other coconut-producing countries. However, to our knowledge, this is the first report of the disease in China. A fungus was isolated from lesion margins of diseased coconut trees. Colonies on potato dextrose agar (PDA) were white, became black 1 to 2 days later, and emitted a strong, fruity aroma.
