盐胁迫下野菊离子的吸收转运情况及相关基因的表达分析
Ion Uptake,Transportation and the Expression of Related Genes in Chrysanthemum indicum Under Salt Stress
[目的]明确抗盐能力不同的野菊(Chrysanthemum indicum)株系在盐胁迫情况下的离子分布运输情况及相关基因的变化规律,从更深层次上认识野菊的抗盐机理,为后续研发和培育新的抗盐品种提供参考。[方法]以前期筛选的 2 个高抗株系(H1、H2)、2 个中抗株系(M1、M2)和 2 个低抗株系(L1、L2)的扦插苗为实验材料,置于 NaCl 浓度为 150mmol/L 的霍格兰营养液中进行盐胁迫处理。测定 6 个离子指标:根、茎、叶的 N…查看全部>>
[Objective]The aim of this study was to elucidate the ion distribution and transport characteristics of various Chrysanthemum indicum strains with differing salt tolerate abilities under salt stress.Additionally,the study also aimed to investigate the changes in related genes.In order to gain a deeper understanding of the salt tolerance mechanism of Dendranthema indicum and provide a reference for the subsequent development and cultivation of new salt-tolera…查看全部>>
