【摘要】 利用光学显微镜和扫描电镜观察了猪笼草[Nepenthes mirabilis(Lour.)Druce]变态叶的表皮特征。结果表明:(1)叶片、瓶状体和瓶盖表面均具气孔器和星状毛,表皮细胞形态相似;(2)瓶盖下表皮和瓶状体下部内表皮密布腺体;瓶盖下表皮的腺体圆形并平覆于表皮上;瓶状体下部内壁腺体由"头部"和"外被"组成,并隆起于表皮上;(3)瓶状体口缘由纵向的细棱组成,细棱之间具袋状横纹;(4)瓶状体上部的内表皮平滑,表面形成拒水蜡层。更多还原

【Abstract】 Epidermal features of the modified leaf of Nepenthes mirabilis were observed with a light microscope and a scanning electron microscope(SEM),respectively.The results were as follows:① Stomata and stellate trichome were presented in the epidermis of leaf,pitcher and pitcher lid,and shape of all epidermal cells was similar.② The round glands existed densely in lower epidermis of pitcher lid,while glands,as"head"and"cover",humped in inner epidermis of bottom pitcher.③ The peristome of pitcher consisted of longitudinal ribs,and corsswise bursiform markings occurred among the ribs.④ The inner epidermis of upper pitcher was smooth and coated with a water-resistant wax layer.更多还原
