UV-B辐射增强对水稻蛋白质及核酸的影响研究

Effects of enhanced ultraviolet-B radiation on soluble protein and nucleic acid in rice leaves

    摘要
  • 摘要: 盆栽试验研究UV-B辐射增强对水稻蛋白质及核酸的影响结果表明，UV-B辐射增强抑制水稻生长，降低水稻生物量和水稻叶片可溶性蛋白质及核酸含量。随UV-B辐射的增强，水稻叶片蛋白水解酶和核糖核酸酶活性上升，硝酸还原酶活性下降，叶片总游离氨基酸含量增加。

     

    Abstract: Effects of enhanced ultraviolet-B radiation on soluble protein and nucleic acid in two rice cultivars(Oryza sati L．)under pot condition were investigated The results show that enhanced ultraviolet-B radiation decreases the biomass．the contents of soluble protein and nucleic acid in rice．With the UV-B radiation increasing．the activities of proteinase and RNase and the content Of tota1 free amino acids increase．while the activity Of NRase decreases．
