摘要
以长白山区分布的大花杓兰、斑花杓兰、杓兰、山西杓兰、东北杓兰、大白花杓兰6种杓兰属植物为试材,对其进行叶片表皮观察研究。结果表明:6种杓兰的叶片表皮细胞形状不规则,垂周壁波状,不同种类的波形不同,气孔均在下表皮随机分布,山西杓兰的气孔呈椭圆形,其余为圆形或近圆形;叶片表皮均有柔毛,大花杓兰与大白花杓兰的柔毛有4节,其余为3节,斑花杓兰的叶片纹饰为波浪状,其余种类为沟纹状。不同杓兰属植物的叶片表皮特征差异可以作为该属内的分类依据。
Taking Cypri pedium macranthum , Cypri pedium guttatum , Cypri pedium calceolus, C y pri pediurn shanwiense , Cypripedium ventricosum, Cypripedium macranthum Sw. f of 6 Cypripedium species which distributed in Changbai mountains as test materials, the characters of leaf epidermis from them were studied. The results showed that the leaf epidermis cells of 6 Cypripedium were irregular shapes, the anticlinal walls were waving undular, but the waveforms were different. Stomatas were randomly distributed on the lower epidermis. The stomata of Cypripedium shansciense was oval,the rest species were round or nearly round. All of the leaf epidermis were pubescent, the pubescences of Cypripedium macranthum and Cypripedium macranthum Sw. f. had 4 sections, the rest 3 sections. The blade grain of Cypripedium guttatum were wavy, the rest ditch lines. Different characters of leaf epidermis could be the basis classifications of inside.
