以花生(Arachis hypogaea cv.)山花9号为试验材料,采用砂基培养法,研究了6种不同铁浓度Hoagland溶液处理下花生幼苗总叶绿素含量﹑丙二醛(MDA)含量﹑超氧化物歧化酶(SOD)﹑过氧化物酶(POD)酶活性的变化. 结果表明,叶绿素a/b比值和MDA含量随着铁浓度的升高先降低后升高,0.05× 10-3 mol/L处理最低;总叶绿素含量﹑SOD和POD活性先升高后降低,0.05×10-3 mol/L处理最高. 综合分析认为,铁浓度超过0.10×10-3 mol/L时,会对砂基培养的花生幼苗产生毒害,砂基培养下花生幼苗生长发育的最适螯合硫酸亚铁浓度应为0.05×10-3 mol/L.

Peanut (Arachis hypogaea CV.)Shanhua NO.9 seedlings cultured with sand culture method were used as experi-mental material,treated with six iron concentration Hoagland solutions.The chlorophyll content, Chl.a/Chl.b ratio, malondialde-hyde content,SOD and POD activity were explored.The results showed that the Chl.a/Chl.b ratio and MDA contents were first decreasing and then increasing with the increasing of iron concentration,the chlorophyll content,SOD and POD activity were first increasing and then decreasing with the increasing of iron concentration,the maximum or minimum value founded in the 0.05×10-3 mol/L Fe2+ treatment.By the results, more than 0.10×10-3 mol/L Fe2+ treatments showed the toxic effects in sand culture method of peanut seedlings, the 0.05×10-3 mol/L Fe2+ concentration in Hoagland nutrient solution was the most opti-mal for peanut growth and development.
