| 摘 要： | 就茉莉酸甲酯（ＪＡ－Ｍｅ）对莴苣幼苗侧根原基的形成以及侧根原基形成过程中内源激素含量的影响进行了探讨。采用不同浓度ＪＡ－Ｍｅ以及分别配以生长素类试剂来处理莴苣幼苗，发现适当浓度的ＪＡ－Ｍｅ可促进其侧根原基形成且对萘乙酸（ＮＡＡ）、吲哚丁酸（ＩＢＡ）及吲哚乙酸（ＩＡＡ）等的促侧根形成具有明显的加合效应，进一步对其侧根原基形成过程中内源激素含量进行测定。结果表明，这与ＪＡ－Ｍｅ配合处理迅速降低根中内源［玉米素核苷（ＺＲｅ）＋异戊烯腺嘌呤（ｉＰＡｓ）］／ＩＡＡ的比值有关。

| Abstract: | Lettuce seedling was treated witnh various concentration of JAMe and 3 kinds of somatotropic hormone. The results showed that JAMe at proper concentration enhanced the formation of lettuce lateral root primordia and the effect of NAA, IBA, IAA on the formation of lateral root that was connected with the decline of endogenous (ZRs iPAs)/IAA value. |

| Keywords: | lettue JAMe lateral root primordia endohormone |
