Effects of Selenium on the Germination of Tomato Seeds and Protective System against Active Oxygen under Salt Stress
HAN Guangquan1, LI Jun2, SONG Manman2, LIU Huiying1
A tomato was the experiment material in this study.The purpose was to explore the effect s of putrescine on the tomato seed germination under NaC1 stress.The tomato cultivar shuangfeng87-5and jiahe2were chosen as experiment material, which were soaked with different concentrations of selenium to determine the effect s on tomato seeds under 100mmol/L NaC1stress.The result s showed that, in the range of low concentrations, the germination rate, germination index, vigor index and Enzyme System increased, and MDA concentration decreased gradually with the rise of selenium concentration in seed soaking.Seeds soaked with appropriate concentration of selenium (0.004mmo1/L) could promote the germination of tomato seeds under NaCl stress.The optimal effect could be obtained when the concentration of selenium reached0.004mmol/L.
