以1年生桉树广林9号为试验材料，测定其叶片可溶性糖、可溶性蛋白、游离脯氨酸、MDA 及 SOD 四季的变化情况，分析季节之间的差异性。结果显示：桉树叶片可溶性蛋白含量顺序是秋季＞冬季＞春季＞夏季；游离脯氨酸含量顺序为冬季＞秋季＞春季＞夏季；可溶性糖含量顺序是春季＞秋季＞冬季＞夏季。活性氧失衡主要体现在冬季，表现为 SOD 活性水平较低；MDA 极显著高于其他季节；该三类指标的季节变化为：MDA 含量在冬季显著高于其他季节，春秋无显著差异，夏季最低；SOD 活性最高是夏季，其他3个季节较低且无显著差异。

This research covers the study of the changes of soluble sugar,soluble protein,free proline, MDA and SOD of Eucalyptus leaves in different seasons,taking the one year old GL9 as testing materi-al.The results indicated that the change trend of soluble sugar content of Eucalyptus leaves in four sea-sons was summer > spring > autumn > winter,the soluble protein content was spring > winter >autumn > summer,and the free proline content was winter >autumn>spring> summer.The imbal-ance of active oxygen mainly manifested in winter,characterized by MDA,which was significantly high-er than that in other seasons,while SOD activities showed lower levels.The seasional change of the three indexs was as follows:MDA content was significantly higher in winter than that in other seasons. There is no significant difference between Spring and Autumn,Summer is the lowest.SOD activity was highest in summer,and there is no significant difference among other seasons.
