Leaf morphology and anatomy of 4 successional dcciduous broadleaved tree seedlings grown under various light levels were examined in relation to their photosynthetic capacity. The successional growth sites of seedlings of birch (Betula schmidtir), oak (Quercus serrata), Keyaki (Zelkova serrata) and maple (Acer tenuifolium) are respectively sunny open, open or gap, gap and shade environment in a forest. Before the bud break, seedlings were transplanted from a small gap or under forest canopy to open nursery. Birch was also transplanted from open site to the nursery. A positive correlation between leaf thickness and the maximum photosynthetic rate of all species was found. For the seedlings grown under shade in the preceding year, oak, Keyaki and maple leaves bore one palisade parenchyma layr even though their leaves unfolded under full sunlight in the nursery. In contrast, leaves expanded under full sunlight in previous year had two palisade parenchyma layrs except for maple where only one layr formed irrespective of growth light environment. Chlorophyll b content of all leaves developed under shade was higher then those grown in the open. In an open, stomatal density was high while the size of bundle sheath extension compartment (area divided by the extension of vascular bundle sheathes) was small. The ecological relationship among leaf morphology, anatomy and its gas exchange capacity in seral tree seedlings is discussed with special reference to the timing of leaf primordial differentiation.

与它们的光合作用能力相关，研究了在各种光水平下生长的4种连续性宽叶幼苗的叶片形态和解剖结构。桦树（Betula Schmidtir），橡树（Quercus serrata），Keyaki（Zelkova Serrata）和Maple（Acer tenuifolium）的幼苗幼苗的演替生长部位是阳光明媚的开放，开放式，开放或缝隙，间隙，间隙，间隙，间隙和遮阳环境。在芽中断之前，从一个小间隙或森林冠层下移植了幼苗以打开托儿所。桦木也从开放地点移植到托儿所。发现所有物种的叶厚与最大光合速率之间的正相关。对于上一年在阴影下生长的幼苗，橡木，凯基和枫木叶有一个帕利塞德实质的雷尔，即使它们的叶子在托儿所的阳光下展开。相比之下，去年在全阳光下膨胀的叶子有两个帕利萨德实质外层，除了枫树外，只有一个莱尔形成了一个layr，而不论生长光环境如何。在阴影下开发的所有叶子的叶绿素B含量比在开放中生长的叶子含量更高。在开放的，气孔密度高，而束套管延伸室的大小（除以血管束外套的延伸区域）很小。讨论了叶片形态，解剖结构及其在静脉树幼苗中的气体交换能力之间的生态关系，并特别提及叶子原始分化的时间。
