The effects of different concentrations of Cr(superscript 6+)(0, 10, 20, 50, 100 mg/L K2Cr2O7) on the content of Pro, malondialdehyde, membrane permeability, activities of protective enzyme SOD and POD in roots and epicotyls of maize seedlings were studied.

研究了不同浓度(0， 10， 20， 50， 100mg/L K2Cr2O7)Cr(上标 6+)胁迫对玉米幼苗根和上胚轴中脯氨酸和丙二醛含量、细胞膜透性、超氧化物歧化酶及过氧化物酶等保护酶活性的影响。

The results were as the follows: with the rising of Cr(superscript 6+) concentration, the Pro content in both root and epicotyls was first up and then down; the content of MDA and membrane permeability increased continuously; SOD activity deceased gradually and POD activity was first up and then down.

结果表明，随着Cr(上标 6+)胁迫浓度的增加，根和上胚轴中Pro含量呈先升后降的趋势，MDA含量和细胞膜透性则持续递增，SOD活性逐渐下降，POD活性先升后降。
