生長素是第一個被發現的植物激素。生長素中最重要的化學物質為3-吲哚乙酸。生長素有調節莖的生長速率、抑制側芽、促進生根等作用，在農業上用以促進插枝生根，效果-顯著。
生長素即吲哚乙酸，分子式為C10H9NO2，是最早發現的促進植物生長的激素。英文來源于希臘文auxein（生長）。吲哚乙酸的純品為白色結晶，難溶于水。易溶于乙醇、乙-醚等有機溶劑。在光下易被氧化而變為玫瑰紅色，生理活性也降低。植物體內的吲哚乙酸有呈自由狀態的，也有呈結合（被束縛）狀態的。后者多是酯的或肽的復合物。植物體內自由態吲哚乙酸的含量很低，每千克鮮重約為1-100微克，因存在部位及組織種類而異，生長旺盛的組織或器官如生長點、花粉中的含量較多。
