Abstract: The germination characteristics at different temperatures and different illuminations in Agrostemma githago L.,Diauthus barbatus,Dianthus Chinensis ,Silene armeria, Silene pendula and Salvia farinaeea was analyzed .The results showed that seed germination rate, germination vigour and germination index under Oh and 12h light conditions were significantly higher than that under 24h light condition in A.githogo L.,D.barbatus, D.Chinensis, S.armeria and S.farinacea; germination rate, germination vigour and germination index under 12h light condition were significantly higher than that under other treatments for S.pendula. Germination rate,germination vigour and germination index of seeds were higher at temperature of 15℃-25℃ in A. githago L.,D. barbatus,D.Chinensis,S.armeria,S.pendula and S.farinacea, and they were relatively lower at temperature higher than 25; Germination rate, the germination vigour and germination index of S.pendula were significantly reduced at temperature higher than 20℃.
