| 摘 要： | 以北京地区生长的常绿阔叶植物北海道黄杨为材料,应用光学显微镜和电子显微镜研究其叶片结构在不同季节的适应性变化。结果表明：叶片上下表皮外覆盖一层厚角质。从新叶期（4月）到休眠期（1、2月）,叶片厚度、栅栏组织、海绵组织及角质层的厚度逐渐增大,而组织疏松度依次降低,各结构数值不同季节差异显著。新叶期和生长季节,叶绿体内积累...

| Abstract: | The mesophlly cell structure of Euonymus japonicus 'Cu Zhi' in different growing periods in Beijing area was observed under microscope and transmission electron microscope in this paper.The results showed that there were relatively thicker cuticular membranes on the upper and lower edidermise.Thickness of leaves,palisade tissues,spong tissue and cuticular membrane were enhanced gradually from new leaf period to dormant season period.But the spong ration was lower in the same period.In the season of new leaf... |
