Keyword:  玉米耐盐性鉴定评价;
Abstract: 对14个玉米品种的芽期、苗期、全生育期进行耐盐性鉴定,将穗长、穗粗、行粒数、穗行数、秃尖长、百粒质量等性状的T/CK与全生育期耐盐指数(STI)进行相关分析.结果表明,STI与穗长、穗粗、行粒数、百粒质量的T/CK呈正相关,且达显著或极显著水平;STI与秃尖长呈负相关,达到极显著水平.M14(蠡玉37)在3个时期均表现出较高的耐盐性,而且具有良好的生产潜力,在全盐量0.15% ~0.25%的盐渍化土壤上具有一定的推广利用价值;M2(浚单20)、M4(京单28)、M9(锐步1号)在芽期耐盐性较差,但苗期和全生育期有较高的耐盐性,因此,在保证发芽的条件下,有一定的推广应用价值.
