Abstract:Micropropagation was studied of four brometiad plants Aechmea fasciata，Vriesea poelmsnii, Cryptanthus zonatus and Neoregelia carolinae, cultured by stem explants．Induction medium of MS+NAA 0.5 mg L-1+BA 5 mg L-1 led to budding after one or two weeks of culture． MS+BA l mg L-1 +NAA 0.l mg L-1 was the optimum medium in subculture． The optimum concentration of NAA was 0.5 mg L-1 in rooting. Plantlets transplanted oil media contained coconut-bant:sand=1：l or coconut-bant：turf：vermiculite (1：1：1) had better surviva1 rate up to 95％ ．
