摘　　要： 以绿豆下胚轴插条为实验材料,研究了乙烯利、ACC、AOA和AgNO3对其不定根形成的影响。结果表明:乙烯利和ACC能促进绿豆下胚轴插条的生根,最适浓度分别为50μmol/L和10μmol/L;AOA和AgNO3 明显抑制不定根形成,随浓度增加,抑制作用增强。插条离体后24h内对ACC的促进作用和AOA的抑制作用敏感。插条在0-6h和18-24h用ACC处理,在0-2h和22-24h用50μmol/L乙烯利处理的生根效果好。乙烯在不定根形成的诱导期和起始晚期起促进作用。 Effects of ethephon, 1-aminocyclopropane-1-carboxylic acid (ACC), aminioxyacetic acid (AOA) and AgNO3 on adventitious rooting in mung bean hypocotyl cuttings were studied. Results indicated that ethephon and ACC promoted adventitious root formation in mung bean hypocotyl cuttings, the optimal concentrations being50 μmol/L and 10 μmol/L respectively, whereas AOA and AgNO3 significantly inhibited adventitious rooting, and the effect of which were dose-dependent. The promoting effect of ACC and the inhibitory effect of AOA on the cuttings excised after 24 hours were sensitive. The rooting effects were best in treatment with 10μmol/L ACC for 0-6 hours and 18-24 hours, and in treatment with 50 μmol/L ethephon for 0-2 hours and 22-24 hours. It is concluded that the promoting effects of ethephon and ACC on adventitious rooting were at induction stage and late initial stage.
