基于花粉粒扫描电镜特征的柴松分类地位研究
Taxonomical Status of Pinus tabulaeformis f.shekannesis Yao et Hsü Based on Morphological Characteristics of Pollen Grain under SEM
摘要
Abstract
Morphological characteristics of the pollen grains of 6 Pinus species were examined and compared by using the scanning electron microscope (SEM) and statistical method. The mean values of pollen size of 6 species ranged from 48. 22 to 55. 05 μm, belonging to disaccate pollens. Transition was distinct between proximal face and the bladder. Germinal furrow formed clear striate between two bladders. Cluster analysis indicated that the P. Tabulaeformis f. Shekannesis Yao et Hsu could be a variety of P. Tabulae formis Carr. Based on the magnitude of grains in the corpus surface, the evolutional order in 6 Pinus species was P. Tabulaeformis Carr, P. Tabulaeformis var. Mukdensis Uyeki, P. Tabulae formis f. Shekannesis Yao et Hsu-→P. Massoniana Lamb→P. Henryi Mast.关键词
