图6 干旱胁迫对转基因植株中SOD活性和MDA积累量的影响 A: 干旱胁迫4周后, 转基因烟草和野生型烟草植株的超氧化物歧化酶(SOD)活性; B: 干旱胁迫4周后, 转基因烟草和野生型烟草植株的丙二醛(MDA)含量。数据表示为means ± SD (n = 3)。** 表示用Student’s t-test在0.01水平差异显著。缩写同图4。

Fig. 6 Effects of drought stress on SOD activity and MDA accumulation in transgenic plants A: the superoxide dismutase (SOD) activity in transgenic plants and WT grown for four weeks under drought stress; B: the malondialdehyde (MDA) content in transgenic plants and WT grown for four weeks under drought stress. The error bars indicate ± SD (n = 3). ** indicate significant difference at the 0.01 probability level based on Student’s t-test. Abbreviations are the same as those given in Fig. 4.
