Based on Monnier's medium (1990),polyethylene glycol (PEG) 1500,180g/l was found optimum for pollen germination of chrysanthemum Dendranthema×grandi flora (Ramat.) Kitam,at which the germination percentage reached at 30%.Combining PEG 1500 180g/l and different concentration of sucrose showed promotion effects 54.1% germination at PEG 1500 180g/l + sucrose 100g/l.The medium can also be used to germinate pollen of Chrysanthemum segetum L.,Bellis perennis and Hymenostemma paludosum (Poiret) Pomel (germination 79%,96.1% and 24.3% respectively at PEG 1500 180g/l + sucrose 200g/l).
