摘要：分别以不同浓度的IBA和GA3激素处理马齿苋组培苗，研究对其生根情况及茎叶发育影响，寻找有利于马齿苋组培苗生长的IBA和GA3的浓度。实验结果表明，浓度0.50mg/L的IBA最适马齿苋组培苗的生根，浓度为1.00mg/L的GA3是最有利于马齿苋组培苗的茎叶的生长。本实验结果有利于马齿苋的快速繁殖，为组培实验研究提供更多的实验材料。

Abstract: The portulaca rooting and the growth of stems and leave, treated by different concentrations of IBA and GA3, were studied. This experiment aim was to find the most suitable concentration of IBA and GA3 to portulaca tissue culture. The results showed the concentration of 0.50mg/L IBA medium was optimal for the portulaca rooting. And the concentration of 1.00mg/L GA3 medium was the most favorable to the growth of portulaca stems and leaves. This experiment results was benefit to the rapid propagation of portulaca and provide more experimental material for study
