低温胁迫对烟草幼苗生化指标的影响及相关性分析

研究了不同胁迫温度对不同类型烟草幼苗（ZY08-4、野生种、栖霞晒烟、K326）生化指标的影响，测定了MDA、游离脯氨酸、可溶性糖、可溶性蛋白等生化指标并对各指标间的相关性进行了分析。结果表明：除对照K326外，3个品种（系）幼苗的游离脯氨酸、可溶性糖含量均随处理温度的降低与胁迫时间的延长呈增加的趋势；MDA、可溶性蛋白则表现出相反的变化，各生化指标间的相关性也达到了极显著性差异。...

Summary:研究了不同胁迫温度对不同类型烟草幼苗（ZY08-4、野生种、栖霞晒烟、K326）生化指标的影响，测定了MDA、游离脯氨酸、可溶性糖、可溶性蛋白等生化指标并对各指标间的相关性进行了分析。结果表明：除对照K326外，3个品种（系）幼苗的游离脯氨酸、可溶性糖含量均随处理温度的降低与胁迫时间的延长呈增加的趋势；MDA、可溶性蛋白则表现出相反的变化，各生化指标间的相关性也达到了极显著性差异。
Bibliography:This experiment studied the effects of different low temperatures on the biochemical indexes of 4 types of tobacco （ZY08-4, wild species, Xixia sun-cured tobacco, and K326） seedlings, determined their contents of MDA, free proline, solu-ble sugar and soluble protein , and analyzed the correlations among these biochemical indexes .The results showed that the free pro-line and soluble sugar contents in the seedlings of three tobacco varieties （strains） （except K326） increased with the decrease in treatment temperature and the lengthening of stress time;while the contents of MDA and soluble protein revealed opposite changes . In addition , the differences in the correlations among various biochemical indexes reached extremely significant level .
