摘要 通过不同浓度的盐溶液(0、50、100、200mmol/L)对番茄种子以及植株进行盐胁迫处理,研究盐胁迫对番茄种子萌发及番茄成熟植株叶片中丙二醛含量的影响。结果表明:50mmol/L的NaCl溶液就能够抑制番茄种子的发芽率,100mmol/L和200mmol/L NaCl溶液状态下,番茄种子的发芽几乎完全被抑制,随着盐浓度的增加,番茄植株丙二醛含量成上升趋势,说明受到盐害加重。 Tomato seeds and seedlings had been treated by different concentrations of NaCl solutions(0,50,100,200 mmol/L),then seeds germination were observed and the malondidehyde content of tomato seedlings were detected.The results showed that the germination rate of tomato seeds had been decreased under 50 mmol/L NaCl solution,the germination was almost completely inhibited under 100 mmol/L or 200 mmol/L NaCl,with salt concentration increased, the malondidehyde content tended to be elevated,this suggested that the injury suffered by the plant was increased.
