Abstract: Ultracytochmical localization of ATP􀀁ase act ivity was carried out using a leading phosphate precipitation technique in the cells of two different chilling resistance Jasminum sambac L. Ait. seedlings. Under 0 ! chilling stress, the ultrastructure of cells and the ATP􀀁ase activity in the chilling resistant Jasmine ( double petal cultivar) was obviously more stable than that in the chilling sensitive Jasmine ( single petal cult ivar) . The ATP􀀁ase in Jasmine seedlings cells of mesophyll mainly located on plasmolemma, tonoplast , chloroplast lamellae, mitochondria cristae, and plasmodeslma , whereas
the ATP􀀁ase in cells of minor leaf vein mainly located on the sieve element and the companion cell.
