摘要
试验对9叶龄的盆栽烟草进行了淹水、低温以及淹水或低温交叉处理,测定了各处理烟草叶片的相对电导率、丙二醛含量、POD和SOD活性、蛋白质含量、可溶性糖含量及烟草生物量等指标,观察了各处理恢复7 d时的生长情况。结果表明,低温、水涝以及低温或水涝的交叉处理均严重影响烟草的各项生理生化指标和生长发育,各处理对烟草的伤害程度依次为淹水2 d后再0℃低温处理2 d>0℃低温处理2 d后再淹水2 d>淹水2 d>0℃低温处理2 d。
The pot-cultured tobacco plants with 9-leaf were tested under waterlogging, low temperature, wat erlogging +low temperature condition and the relative conductivity, MDA, protein and soluble sugar content, POD and SOD activity, its biomass and growth situation were determinated after 7 days from its recovery growth. The results showed that three treatment conditions seriously affected tobacco physiological-biochemical indexes and its growth and development, and the damage degree of three treatment conditions was 2days waterlogging +0℃ 2 days 0℃+2days waterlogging〉 2days waterlogging〉2 days 0℃.
