Observation on the vessel elements of secondary xylem in jackfruit artocarpus heterophyllus 菠萝蜜次生木质部导管分子观察
Comparative anatomical studies on the vessel elements in the secondary xylem of juglandaceae from china and discussion on their evolutionary position 国产胡桃科次生木质部导管分子的比较解剖及其系统位置的讨论
Video cytological image analysis system and micrography were adopted to examine vessel elements in secondary xylem of phyllanthus emblica 摘要运用细胞图象分析系统及显微照相的方法，对余甘子次生木质部导管分子进行观察研究。
The vessel elements of secondary xylem in litchi chinensis are observed and studied by bio - microscope image analysis system and micrography 摘要运用细胞图像分析系统及显微照相的方法，对荔枝次生木质部导管分子进行了观察研究。
It was shown that vessel elements in secondary xylem of p . emblica have many different forms and most of them have tails and their perforation plates divide into two types : ( 1 ) there is one simple perforation plate at each end of the vessel elements and ( 2 ) there is one simple perforation plate at one end of the vessel elements and two simple perforation plate at the other end ; ( 3 ) a few vessel elements have special inclusions ; ( 4 ) the intervascular pits are alternate pits ; ( 5 ) the pits between the vessels and rays are mixed pits , pits with transverse gashes and scalariform pits 结果发现，余甘子次生木质部导管分子中存在着许多不同的样式，导管分子大多数具尾；其穿孔板存在着两种类型： ( 1 )两端均为1个单穿孔板； ( 2 )一端为1个单穿孔板;另一端为2个单穿孔板； ( 3 )极少数的导管分子具有特殊的内含物； ( 4 )管间纹孔式为互列纹孔式； ( 5 )导管射线间纹孔式为混合型纹孔与横列刻痕状纹孔以及梯状穿孔。
