[Effect of waterlogging on senescence of winter wheat root system at booting stage].
By applying 3 winter wheat cultivars of different water-resistance, the effect of waterlogging at booting stage on the growth and development of root system, 32P absorption and its distribution, and senescence of root system was studied with soil column culture. Waterlogging at booting stage reduced root dry weight, its activity and SOD activity, and increased the relative permeability of plasma membrane and the membrane-lipid preoxidation level(MDA content) of root system. Meanwhile, waterlogging influenced the 32P absorption, transportation and distribution, and consequently, speeded up the senescence of root system.
