生長素是第一個被發(fā)現(xiàn)的植物激素。生長素中最重要的化學物質(zhì)為3-吲哚乙酸。生長素有調(diào)節(jié)莖的生長速率、抑制側(cè)芽、促進生根等作用,在農(nóng)業(yè)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(fā)現(xiàn)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(jié)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?yōu)槊倒寮t色,生理活性也降低。植物體內(nèi)的吲哚乙酸有呈自由狀態(tài)的,也有呈結(jié)合(被束縛)狀態(tài)的。后者多是酯的或肽的復合物。植物體內(nèi)自由態(tài)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。
