| 摘 要： | 对灯台树茎次生木质部离折材料进行观察研究，发现其导管分子穿孔板有梯状穿孔和单穿孔板2种类型，并且其单穿孔板的穿孔外展。具不同类型穿孔板的导管分子有4种类型，即两端均为梯状穿孔板的导管; 端是梯关穿孔板，另一端是单穿孔板的导管分子；一端有2个单穿孔板，另一端是梯状穿孔板的导管分子；两端均为单穿孔板的导管分子。

| Abstract: | Educing and observing the stem's secondary xylem of Cornus controversa revealed there are two types of perforation plates , scalarform perforation plate and simple perforation plate, and the perforation of the simple perforation plate is extended.There are 4 types of vassel elements with different types of perforation plates: both ends of the vassel element are scalarform perforation plate; one end scalarform type, the other simple type; one end two simple types, the other end scalarform type; both ends simple type. |
