摘 要 ：以耐湿性不同的3个冬小麦栽培品种为试验材料，采用土柱栽培法，研究了孕穗期土壤渍水逆境对冬小麦根系生长发育、³²P的吸收、分配及根系衰老的影响。结果表明，孕穗期土壤渍水逆境初期（0～5 d），单株根干重略有增加；渍水5 d后，根系干重、根系活力和根系SOD活性开始下降，根系质膜相对透性和膜脂过氧化水平（M

Abstract:The effects of waterlogging to growth and development of root system at booting stage, ³²P absorption and distribution, and senescence of root system were studied with soil column culture method, using 3 winter wheat cultivars with different waterlogging-resistance. Waterlogging at early
