Cu污染对玉米幼苗生理生化的影响
Effects of Cu Pollution on Physiological and Biochemical Characteristics of Maize Seedlings
摘要: 通过采用Hoagland营养液培养的方法，研究Cu污染对玉米幼苗生理生化的影响，对玉米的产量品质有重要意义。结果表明：随着铜溶液浓度的升高，叶绿素a的含量和叶绿素总含量呈先下降后微上升的趋势，叶绿素b的含量相对稳定；可溶性糖含量增加；蛋白质的含量先增加后下降，总体呈下降趋势；POD的含量先快速上升后有所下降，总体呈现上升趋势；CAT的含量是先下降后上升再下降。
Abstract: The effects of Cu pollution on physiological and biochemical characteristics of maize seedlings were studied by Hoagland nutrient solution culture, which is of great significance to the yield and quality of maize. The experimental results showed that with the increase of copper solution concentration, the content of chlorophyll a and the total chlorophyll content showed a slight increase trend. Relatively stable content of chlorophyll b, the content of soluble sugar showed an increasing trend. The content of protein first rose and then fell, and the overall trend was decreasing. The content of POD rose rapidly first and then decreased, but it showed an upward trend. The content of CAT decreased first and then increased and then decreased.
