摘　　要：在水、气等适宜的条件下 ,G10 1和新葵杂 4号的发芽最低临界温度分别为 3.2℃和 3.7℃ ,出苗最低临界温度分别为4℃和 5℃ ,两品种发芽的适宜温度为 2 0～ 30℃ ,出苗适宜温度为 2 5～ 30℃ ,当≥发芽临界温度的有效积温达 4 6～ 5 1℃时 ,种子发芽 ;≥出苗临界温度的有效积温达 10 8～ 113℃时 。As other requirements for seed germination were met,the minimum germination and seedling emergence temperature of G101 and Xin kuiza No.4 were 3.2～3.7℃and 4～5℃.The optimal germination and seedling emergence temperature were 20～30℃ and 25～30℃.When the effective accumulated temperature of ≥ the minimum germination temperature was over 46～51℃,seed germinated; the minimum seedling emergence temperature was over 108～113℃,seedling emerged.
