Seed lots of sweetgum (Liquidambar styraciflua L.) from the montane cloud forests of Mexico germinated more rapidly and completely over a range of low temperatures, 4.5 to 16° C, than seed lots from the United States. Light and stratification were not required for germination of Mexico seeds. Peak germination was later for Illinois and New Jersey seed lots than for Texas and Florida collections. Forest Sci. 17:34-36.
