摘　　要：为探讨不同油葵种子萌发期耐盐特性,以3个油葵品种为供试材料,在发芽期采用相同质量浓度的混合盐碱处理,研究其对油葵品种主要发芽特性的影响。结果表明,低浓度盐碱(0.2%、0.4%)在一定程度降低出油至尊909s,s606,NUS606的发芽率;中高浓度盐碱(≥0.6%)降低各品种种子的发芽率,盐害率则随浓度增大而增大。低浓度的复合盐碱抑制油葵萌发,而高浓度盐碱对供试品种的萌发有强烈的抑制作用。不同品种对盐碱的耐受力不同,低盐碱浓度下出油至尊909s,s606表现相似且良好,NUS606较弱;中高盐碱浓度处理下,s606表现较好,出油至尊909s次之,NUS606较弱。In order to explore the salt tolerance characteristics of different oil sunflower seeds during germination,three oil sunflower varieties were treated with the same mass concentration of mixed saline-alkali during germination,and their effects on the main germination characteristics of oil sunflower varieties were studied.The results showed that the low concentration of saline-alkali(0.2%,0.4%)reduced the germination rate of oil-producing supreme 909s,s606,and NUS606 to a certain extent;the medium and high concentration of saline-alkali(≥0.6%)decreased the germination rate of all varieties,and the salt damage rate increased with the increase of concentration.Low concentration of compound saline-alkali inhibited the germination of oil sunflower,while high concentration of saline-alkali strongly inhibited the germination of the tested varieties.The tolerance of different varieties to saline-alkali was different.Under low saline-alkali concentration,the performance of s606 was similar and good,and the NUS606 was weak.Under the treatment of medium and high saline-alkali concentration,s606 was better,followed by oil-producing 909s,and NUS606 was weak.
