鹤山重建植被的几种优势种叶解剖学研究

Study on leaf anatomical characteristics of dominant spedes of rehabilitation vegetation in Heshan

对南亚热带鹤山恢复植被５种优势种湿地松(Ｐｉｎｕｓ ｅｌｌｉｏｔｔｉｉ),马占相思(Ａｃａｃｉａｍａｎｇｉｕｍ),大叶相思(Ａｃａｃｉａａｕｒｉｃ－ｕｌａｅｆｏｒｍｉｓ),九节(Ｐｓｙｃｈｏｔｒｉａｒｕｂｒａ)和南洋楹(Ａｌｂｉｚｉａｆａｌｃａｔａ)进行了叶解剖学研究。结果显示,变化表现在表皮角质膜的厚度。细胞壁的厚度和形状,叶肉组织中海绵组织和栅栏组织的分化,内皮层维管束的构造等。为以后进一步探讨植被恢复过程中叶解剖结构的变化提供了实验基础。

Leaf anatomical characteristics of five dominant species , Pinus elliottii, Acacia mangium, Acacia, auriculaeformis, Psycho-tria rubra, Albizia falcata of rehabilitation vegetation in Heshan, Guangdong, China,were studied. Results showed that there are variations in the thickness of adaxial and abaxial cuticles, the thickness and shape of cell wall, the differentiation of leaf spongy tissue and palisade tissue in mesophyll, the structure of leaf bundle of the endoderm. It provided an experimental data for further study of leaf anatomical characteristics during the restoration process of vegetation.
