为了探索湖南烟稻轮作地烤烟的最优育苗方式,研究了不同育苗方式对烤烟大田期抗氧化系统酶活性的影响。结果表明:（1）在大田期,烤烟SOD和POD活性变化趋势表现为"降-升-降",CAT活性变化趋势表现为"降-升-降-升",APX和GR活性变化趋势表现为"升-降";（2）烤烟CAT、POD、APX、GR的活性最高时期为旺长期,SOD的活性最高时期为打顶期,抗氧化系统酶活性最低的时期为成熟期,表明烤烟在旺长期阶段抗氧化酶活性最高,在成熟期阶段酶活性最低;（3）在不同的育苗方式下,烤烟大田期抗氧化系统酶活性之间差异显著（p

To explore optimal raising seedling patterns of flue - cured tobacco in tobacco rice rotation fields of Hunan prov-ince ,the effect of different raising seedling patterns on activities of antioxidant enzyme of flue - cured tobacco during field condition was studied. The results showed that ： （1 ） the activities of SOD and POD in flue - cured tobacco showed a simi-lar ＂drop - ascend - drop＂ tendency during field condition. The activity of CAT in flue - cured tobacco showed a similar ＂ drop - ascend - drop - ascend＂ tendency during field c...
