Abstract/Contents:"12 varieties of Poa pratensis L. were treated with PEG-6000 solution at concentrations of 0(CK), -0.3, -0.6, -0.9 and -1.2 MPa in order to assess the effects of drought on relative germination rate, ratio of radicle and embryo, germination index as well as drought-tolerance index at germination stage. The results showed that the suitable water potential of Poa pratensis germination was more than or equal to -0.46 MPa and the critical water potential of drought tolerance of Poa pratensis probably around -0.6 MPa at germination stage. At last, the method of comprehensive clustering analysis was used to evaluate the different tolerance of the experimented varieties and the result was 'Apollo', 'Freedom II' and 'Super icelly' had better drought resistance, 'Big bound', 'Resplendence' and 'Midnight II' had good drought resistance, 'Mission', 'America king' and 'Impact' were middle, 'Bluemoon', 'Award' and 'Broad elegant' had worse drought resistance."
