本试验以普通玉米、甜玉米、糯玉米三种类型玉米为试材,探讨铝胁迫对不同类型的玉米根系的生长和生理生化过程的影响,以揭示有关铝的毒害作用机理及其基因型之间的差异。结果表明,在铝胁迫下,玉米的根系生长受到抑制,不同类型玉米的根系形态在铝胁迫下具有明显的基因型差异。铝胁迫能引起玉米根部SOD、POD活性与丙二醛含量的上升,不同类型和同一类型的不同品种间均存在差异。 In this study, the effects of aluminum stress on the growth and physiological and biochemical processes of different types of maize roots were explored using three types of corn, sweet corn and waxy corn as test materials to reveal the toxic mechanism of aluminum and its genotype The difference between. The results showed that the root growth of maize was inhibited under aluminum stress. The root morphology of different types of corn had obvious genotype differences under aluminum stress. Aluminum stress caused the increase of SOD and POD activities and the content of malondialdehyde in maize roots. There were differences among different types and varieties of the same type.
