| 摘 要： | 综合运用室内水培耐盐萌发测试与田间原位耐盐性鉴定,以黄淮海夏玉米区30个主推玉米品种发芽率、发芽势、胚芽长和胚芽重的相对值及盐碱地条件下产量表现作为耐盐性评价依据,采用加权隶属函数法和聚类分析对不同玉米品种耐盐性进行综合评价。结果表明,NaCl浓度≥160 mmol/L时,不同玉米品种萌发均受到显著抑制,萌发期盐胁指标迫敏感程度表现为相对发芽势>相对胚芽长>相对胚芽重>相对发芽率;子粒产量、发芽率、穗数和胚芽重与玉米品种耐盐性最为密切。根据加权隶属函数值和系统聚类分析,可将30个玉米品种分为耐盐性不同的4个类群,其中强耐盐品种4个、中等耐盐品种9个、盐敏感型9个、盐极敏感型8个。160 mmol/L NaCl可作为玉米萌发期耐盐性鉴定的适宜盐浓度,子粒产量、发芽率、穗数和胚芽重可用于玉米品种耐盐鉴选的主要指标。邦玉339、鲁单818、登海605和青农105可用于盐碱地玉米栽培。

| Abstract: | The salt tolerant ability of 30 popularized maize varieties was evaluated by conducting a field experiment, combined with germination test using solution culture. Comprehensive evaluation was based on germination rate, germination potential, shoot length, shoot weight, and its grain yield in field condition. The results showed that the germination of the maize was inhibited when the concentration of NaCl was over 160 mmol/L. The sensitive degree of these indicators for evaluating salt tolerant ability was in the order of RGP > RSL > RSW > RGR. Grain yield, germination percentage, plants per unit, and shoot weight were closely related to salt tolerant ability of the varieties. With the weight membership function method and cluster analysis, these 30 maize varieties can be divided into four groups:high salt-tolerant maize, salt tolerant varieties, salt-sensitive varieties, high sale-sensitive varieties. Thus, 160 mmol/L could be regarded as the suitable concentration for salt tolerant evaluation, and the grain yield, germination percentage, plant per unit and shoot weight could be as the indicator for salt tolerant detection. Bangyu339, Ludan818, Denghai605, and Qingnong105 were four salt tolerant varieties, which could be used for the saline-alkali soil. |
