以烤烟云烟85为供试材料，采用土培盆栽的方法研究了不同pH对烤烟叶片生理生化指标及叶片组织结构的影响。结果表明，pH≥3.0处理烤烟叶片的SOD活性、栅栏组织/叶厚、栅栏组织/海绵组织和脯氨酸含量随pH的降低而升高，而 pH

A pot experiment was carried out to evaluate the effects of different pH value on physiological indices and tissue structure of flue-cured tobacco Yunyan 85.The results showed SOD activities,palisade tissue/leaf tissue value,palisade tissue/sponge tissue value and proline contents in pH≥3.0 treatments increased with pH value decrease.Further decrease in pH value resulted in a decrease in these parameters.The change trend was an inverted ＂V＂-type and pH 3.0 was their turning point.POD activities in pH≤3.0 treatments were significantly higher...
