摘　　要：研究了零磁空间处理小麦风干种子以及在小麦花药培养过程中附加零磁空间处理的生物遗传学效应。结果表明 ,小麦种子在零磁空间处理 1 80d以上会明显抑制种子萌发和幼苗生长 ,表现出与传统γ射线处理完全不同的生物效应 ;在小麦花药愈伤组织诱导过程中附加一定周期的零磁空间处理 ,对小麦雄核发育和最终形成愈伤细胞团有一定的刺激作用 ,有助于促进高质量愈伤组织及其绿苗的获得率。零磁空间处理丰富了小麦花培后代的变异类型 。The biological and genetic effects of magnetic field\|free space treatment on air\|dried seeds and anther culture of wheat were studied. The results showed that the seed germination and seedling growth were obviously inhibited by over 180 days of magnetic field\|free space treatment on wheat seeds and totally different biological effects from traditional γ ray treatment were observed. The magnetic field\|free space treatment in the process of anther callus induction of wheat could stimulate the development of male gamete and final formation of calli, resulting in producing high quality anther calli and high percentage of green plants. The magnetic field\|free space treatment increased the mutant types of doubled haploid population and could be used to upgrade the selection efficiency in wheat haploid breeding.
