摘　　要：本文通过研究不同温度和盐浓度下新疆三种盐生植物盐角草、梭梭和黄花补血草种子的萌发率与发芽势,来分析这三种盐生植物的萌发特性,为进一步研究其抗逆性提供理论数据。在不同温度胁迫下三种盐生植物在5~30℃范围内均能萌发,盐角草适宜萌发温度为5℃,梭梭适宜萌发温度为25~30℃,黄花补血草适宜萌发温度则为20~30℃。在不同浓度盐胁迫下,三种盐生植物的萌发皆表现为低浓度下促进而高浓度下抑制,盐角草适宜萌发盐浓度为0.1~0.4mol·L-1,梭梭和黄花补血草的适宜萌发盐浓度均为0.05~0.1mol·L-1。The germination characteristics of the seeds of halophytes in Xinjiang were analyzed by studying the relationship between germination rate and germination potential of the three types of halophytes under different low temperature and different salt content.Three halophytes can germinate in the range of 5~30℃,The best germination temperature of Salicornia europaea L.is 5℃,Haloxylon ammodendron(C.A.Mey.)Bunge is 25~30℃,and Limonium aureum(L.)Hill is 20~30℃.Under salt stress,all three plants showed low concentration promotion and high concentration inhibition.And 0.1~0.4mol·L-1 was the best germination salt concentration of S.europaea L,while 0.05~0.1mol·L-1 for H.ammodendron(C.A.Mey.)Bunge and L.aureum(L.)Hill.
