| 摘 要： | 利用奈乙酸(NAA)、吲哚乙酸(IAA)、吲哚丁酸(IBA)和2,4-D等4种生长素的不同浓度(0,0.01,0.02,0.05,0.1,0.15和0.2 mg/L)的溶液,分别在MS培养基上对拟南芥萌发的幼苗进行处理,对其生根情况进行测定,结果表明:4种生长素都能抑制拟南芥主根生长,促进不定根生长。2,4-D的抑制作用最明显;IBA与IAA的促进作用差异不显著;NAA在0.05 mg/L时,促进作用最强。

| Abstract: | The germination seedling of Arabidopsis thaliana was treated in MS medium with four kinds of plant growth regulator(NAA.IAA,IBA and 2,4-D) and the different concentrations(0,0.01,0.02,0.05,0.1,0.15 and 0.2 mg/L),respectively and the rooting growth situations were measured.The result showed that the different concentrations of exogenous auxin all inhibited the root development and promoted adventitious root.2,4-D had most signification effect,and IBA and IAA were not signification.0.05?mg/L concentration of NAA had markedly effectiveness. |
