摘要: 以“金边”北美鹅掌楸(Liriodendron tulipifera ‘Aureo marginatum’)为实验材料,通过对其叶片不同色块的叶绿素含量、叶表皮、叶片解剖结构以及叶绿体结构特征等进行比较。叶绿素含量测定表明,“金边”北美鹅掌楸叶片黄色部分的叶绿素a、b均显著低于其绿色部分,黄色部分的叶绿素a/b值大于绿色部分;叶表皮结构特征一致;叶绿体显微和超微结构观察发现,正常叶色部分的栅栏组织细胞细长、排列紧密,叶绿体多且呈椭圆形、结构完整;黄色部分的栅栏组织结构松散,叶绿体形状不规则,无基质与基粒片层,其淀粉粒多。

Abstract: The variety used in this research was Liriodendron tulipifera ‘Aureo marginatum’. The differences in chlorophyll content, leaf anatomical structure and chloroplast ultrastructure between the green part and yellow part were analyzed. The result showed that chlorophyll contents in the yellow part were lower than those in the green part. The ratio of chlorophyll a to chlorophyll b in the yellow part was higher than that in the green part. In the green part, the cells of palisade tissue were slender and arranged densely, and there were more normal chloroplasts which were ellipse. However, in the yellow part, the structure of palisade tissue became loose, there were some abnormal chloroplasts, the grains in the chloroplast were disintegrated, and more starch grains appeared in the chloroplasts.

Key words: Liriodendron tulipifera &lsquo, Aureo marginatum&rsquo, chlorophyll, leaf epidermis, leaf anatomical structure, chloroplast ultrastructure
