| 摘 要： | 以蔓生黄瓜129和矮生黄瓜D0462为试验材料，采用酶联免疫吸附法（ELISA）测定了茎尖、叶片和根的内源激素GA、IAA、ZR和ABA含量，并对内源激素含量差异和动态变化进行比较分析。结果表明：矮生黄瓜D0462各器官的GA含量极显著低于蔓生黄瓜129；生长前期IAA含量高于蔓生黄瓜129，生长中后期IAA含量显著低于蔓生黄瓜129；ZR与ABA含量极显著高于蔓生黄瓜129。矮生黄瓜D0462各器官GA/ABA、IAA/ABA和（IAA+GA+ZR）/ABA的比值都极显著小于蔓生黄瓜129，而ZR/GA的比值极显著大于蔓生黄瓜129。由此推测，矮生黄瓜D0462矮化可能与内源GA含量低有关，并且矮化是多种激素共同作用的结果。

| Abstract: | In this study,sprawl cucumber(Cucumis sativus L.)129 and dwarf cucumber D0462 were taken as experimental materials.The contents of GA,IAA,ZR and ABA of apical meristems,leaves and roots were investigated,respectively by enzyme-linked immunosorbent assay(ELISA).The results showed that the contents of GA in D0462 were very significantly lower than that of 129.However,the contents of IAA in D0462 were higher than that of 129 in early growing stages,but significantly lower in mid and late growing stages.The con... |
