| 摘 要： | 以一年生平邑甜茶幼苗为材料,在水培条件下研究了盐胁迫下平邑甜茶叶片内源游离态多胺、丙二醛（MDA）含量的变化以及外源多胺和多胺合成抑制剂对它们的影响。结果表明：盐胁迫下平邑甜茶叶片中MDA含量显著增加,精胺（Spm）和亚精胺（Spd）含量明显降低,腐胺（Put）含量显著增加,（Spd＋Spm）/Put显著降低,多胺总量...

| Abstract: | Changes in the content of endogenous polyamines and malondialdehyde(MDA) responding to salinity stress and effects of exogenous polyamines and the polyamine biosynthesis inhibitor on polyamines and malondialdehyde(MDA) content were investigated in leaves of 1-year-old Malus hupehensis Rehd.seedlings grown in hydroponic systems.Results showed that the content of free putrescine(Put) was increased,and the content of free Spd and Spm and(Spd+Spm)/Put ratio in leaves were significantly decreased under salt trea... |
