摘要
[目的]探究盐胁迫对芹菜幼苗生理生化特性的影响。[方法]用不同浓度(0、50、100、150 mmol/L)的NaCl溶液模拟盐胁迫,研究其对盆栽芹菜幼苗生理生化特性的影响。[结果]NaCl胁迫下过氧化氢酶活性、丙二醛含量均呈现随着盐浓度、处理天数的增加而升高的趋势;过氧化物酶活性、可溶性糖含量、可溶性蛋白质含量的变化则是在一定的盐浓度范围内随着处理天数的增加而升高,但当盐浓度超过一定的阈值后则表现为随着处理天数的增加先升高后降低的趋势;叶绿素含量的变化则是随着盐浓度和处理天数的增加而下降。[结论]试验结果为我国盐碱地地区芹菜种植提供了理论依据。
[Objective] The aim was to explore effects of NaCl stress on physiological and biochemical characteristics of celery seedlings. [Method]The effects of salt stress on physiological and biochemical characteristics of celery seedlings under different concentrations of NaCl at 0,50,100 and 150 mmol / L. [Result] The CAT activity and content of MDA increased with the increase of NaCl concentration and treating days. The POD activity,content of soluble protein and soluble sugar increased with the increase of treating days within certain NaCl concentration,while they increased firstly but declined later under higher NaCl concentration. The content of chlorophyll declined with the increase of NaCl concentration and treating days. [Conclusion] The results provide theoretical basis for celery planting of saline-alkali land in China.
