| 摘 要： | 本试验以转Bt基因抗虫棉GK 1 2为试材 ,研究不同生育期棉花幼叶、功能叶、衰老叶片、根组织和伤流中内源激素的变化。结果表明 :①细胞分裂素两组分iPA +iP和ZR +Z对叶片、根系建构及功能的调控作用是协同互补关系 ,在幼叶、功能叶、衰老叶片和根组织中iPA +iP和ZR +Z的含量变化趋势相反。iPA +iP和ZR +Z均呈单峰曲线变化趋势 ,其中iPA +iP开口向下 ,ZR +Z则开口向上。②赤霉素两组分GA3 和GA4在幼叶、功能叶、衰老叶片和根组织中的变化趋势相似 ,其中GA3 主要调控着根系和叶片的建构与功能 ,GA4参与调控叶片的衰老。③IAA和ABA在幼叶、功能叶、衰老叶片和根组织中的变化趋势不一致。盛花期之后 ,幼叶和功能叶片中的IAA和ABA含量上升 ,衰老叶片和根组织中的含量下降。ABA启动叶片和根系的衰老过程 ,启动后ABA含量下降。④伤流液中iPA +iP、ZR +Z、GA3 、GA4、IAA和ABA的变化动态均呈单峰曲线。 |

| Abstract: | The changes of endogenesis hormone in young leaves (02)/functional leaves (04)/old leaves (08)/root tissue and root sap in different developing stages of Bt transgenic cotton GK-12 were investigated in 2002 at CAAS. The results showed that: ① iPA+iP contents in young leaves/functional leaves/old leaves and root tissue changed with the changes of ZR+Z contents in different developing stages, but the changes trends were in other way round. The function of iPA+iP and ZR+Z were corresponding and complementary. Both the changes trends of iPA+iP and ZR+Z were single apex curves. ② GA_3 and GA_4, the two members of gibberellic acid, were also measured in this study. The change trends of GA_3 and GA_4 in young leaves/functional leaves/old leaves and root tissue were same. GA_3 was mainly regulating the construction and function of leaves and roots, GA_4 was mainly regulating consenescence of leaves. ③ The change trends of IAA and ABA in young leaves/functional leaves/old leaves and root tissue were different in different developing stage. The content of IAA and ABA in young leaves/functional leaves increased, and the content of IAA and ABA in old leaves and root tissue decreased with the development. ABA start-up senescence process of leaf and root, and then content of ABA declined. ④ The change trends of iPA+iP/ZR+Z/GA_3/GA_4/IAA and ABA content in root sap were single apex curve.= |
