摘要
在稻苗培养液中添加胆碱或乙醇胺能参与稻苗磷脂的合成。磷脂酰胆碱(PC)和磷脂酰乙醇胺(PE)均约增加1倍,且PC 和PE 可相互转化。当培养液中胆碱或乙醇胺的浓度分别为9.0mM 和3.0mM 时,能提高超氧化物歧化酶(SOD)活性;降低丙二醛(MDA)含量及电导百分比,表明它们有保护质膜的作用。胆碱或乙醇胺能显著促进稻苗生长,提高单株叶干物重和苗基部1cm 处的长径。
When choline or ethanolamine was added to the culture solution,theywere utilized for the biosynthesis of phospholipids in rice seedling.Bothphosphatidyl choline(PC)and phosphatidyl ethanolamine(PE)increasedby 100% of the blank.PC and PE.could be interchanged.Choline and eth-anolamine at concentrations 9.0mM and 3.0mM respectively,could raise theactivity of superoxide dismutase(SOD);drop malony dialdehyde(MDA)contentand the electric conductance(in percentage).Choline and ethanolamine couldprotect the cell membrane.In culturing the Seedling with choline and eth-anolamine,it was discovered that they could dramatically stimulate its growth,increase dry weight and diameter 1 cm from the seedling base.
