摘要:
?为探讨外源硅对野生大豆幼苗耐盐性的影响机制，采用水培的方式测定外源硅（K2SiO3）对盐胁迫（NaCl）下野生大豆叶片抗氧化酶活性、叶绿素含量、光合速率和氧自由基（ROS）含量的影响。结果表明：外源硅可以提高盐胁迫条件下野生大豆的生长，降低叶片丙二醛（MDA）、超氧阴离子自由基和过氧化氢（H2O2）的含量，提高超氧化物歧化酶(SOD)、抗坏血酸过氧化物酶(APX)及过氧化物酶（POD）的活性，提高叶绿素含量和光合速率。进一步证实外源硅对于植物的新陈代谢及生理变化具有重要作用。
Abstract:
?In order to explore the mechanism of exogenous sllicion(Si)on improving salt tolerance,the Glycine soja were grown hydroponically to study the effect of exogenous Si on the activities of major antioxidant enzymes,the content of chlorophyll,net photosynthetic rate(Pn),and reactive oxygen species(ROS)in leaves under NaCl stress.The results showed that exogenous Si could enhance growth of salt treatment Glycine soja?and decreased contents of MDA, O2-and H2O2 in leaves under salt stress,while content of chlorophyll,net photosynthetic rate and antioxidant enzymes activities including superoxide dismutase(SOD),peroxidase(POD),and ascorbate peroxidase(APX)were increased.Therefore，exogenous Si could enhance salt tolerance of Glycine soja.The results of the present experiment coincided with the conclusion that Si may be involved in the metabolic or physiological changes in plants.
