摘　　要：研究了不同浓度海水胁迫对广东地区栽培面积较大的尖叶油青菜心、黑叶白菜、奶白菜、红油麦、抗热无斑香油麦、黄芹和意大利生菜7种蔬菜种子发芽率的影响,以期筛选耐盐蔬菜品种,为利用海水进行灌溉提供参考。结果表明:随着海水浓度的升高,种子发芽率呈现下降趋势。50%、60%海水胁迫下种子的萌发抑制作用明显,说明蔬菜萌发时的耐盐能力是有限的。下降程度的差异说明耐盐性不同,有的种子耐盐能力较强,如白菜、尖叶油青菜心;有的种子耐盐能力较弱,如意大利生菜。The germination characteristic under different concentrations seawater-stress in seven kinds of Guangdong vegetable seeds were studied in this paper.The results showed that the seed germination rate declined with the increasing of the seawater concentrations,the seed germination was inhibited obviously under 50%,60% seawater-stress and indicated the salt tolerance of vegetable germination was limited.Difference of decline degree illustrated the different salt tolerance,some seeds had strong salt tolerance,such as Chinese cabbage and flowering Chinese cabbage while salt tolerance ability of Italian lettuce was weak.The results would bring important guiding significance in selecting salttolerance varieties of vegetables and use of seawater for irrigation.
