【摘要】With a total of 30 Rosa chinensis varieties and Rosa multiflora as test materials,the pollen viability was measured by staining and germination,and the varieties was graded according to the pollen germination. The result showed as follows. The germination was suitable for detecting pollen viability,the measurement with 10%sucrose concentration was suitable for the Rosa chinensis and Rosa multiflora varieties pollen germination.‘Rosa multiflora Thunb.var.platyphylla Thory’‘Darthuizer Orang Fire’‘Rosa cymos’and‘Fen He’had the higher pollen germination rate than other varieties,and the rates respectively were 84.20%,71.60%,59.20%and 54.00%,the pollen viability gradually reduced as the extension of storage time. With the pollen germination as the judgment ,Rosa chinensis and Rosa multiflora varieties were classified three grades:the pollen germination of the first grade was more than 50%,‘Rosa multiflora Thunb.var.platyphylla Thory’‘Darthuizer Orang Fire’;the second grade was between 10% and 50%‘,Pink Peace‘’Monica’;the third grade was less than 10%‘,Spectra‘’ Golden Showers’.%以30个月季品种及蔷薇属植物为试验材料，采用沙尔达考夫染色法、悬滴液发芽法测定其花粉生活力，并根据
