英文摘要	Cell damage and shoot survival rates of Plagiomnium acutum under high temperatures were studied by immersing the moss in hot water in the light (wet) and in dark incubators in air ( dry) at various constant temperatures for up to 8 h. At 35-40degreesC no moss cells were damaged (indicated by expansion, contraction, or breach of chloroplasts, total loss of green colour in cells, or protoplast of cell disintegrating), and all moss shoots survived. At 45degreesC, damage to both wet and dry moss cells, and death of moss shoots increased with exposure time. No samples survived prolonged exposure at temperatures of 50degreesC and higher, indicating that the lethal high temperature of Plagiomnium acutum is about 45degreesC. Mosses in air in a dark constant-temperature chamber required a longer time to exhibit cell damage and death, reaching 100% only at 50degreesC and above. Age of tissue, exemplified by position on stem, had no apparent effect on these responses.
