为了了解繁殖树木的竞争和叶量增加的生长模式，对日本本州北部亚高山森林中非抑制繁殖的冷杉树的高度和茎直径之间的生长分配进行了检查。通过将茎体积的相对生长速率除以高度和茎直径生长的相对贡献来分析生长分配。在9年期间，高度生长和籽球产量表现出明显的年度变化，而茎直径生长则出现中等变化。在 9 年期间，在球果生产的三年中，有两年，球果产量较大的树木与球果生产的下一年的高度增长较少相关；然而，在种球生产当年，没有出现高度增长的趋势。在肥大播种的第二年，茎体积生长较大的树木与高度生长较少相关。 9年期间累积茎体积生长与生长分配到高度之间的关系也显示出这种趋势，表明生物量增加较大的树木会抑制光合产物的分配，从而产生大量的繁殖支出。与此相反，生物量增加较小的树木可能会分配光合产物来与周围的树木竞争。这项研究的结果表明，生活史中生殖器官的增加和繁殖的年度变化与A中茎的生长模式密切相关。 玛丽斯树。
To understand the growth patterns with respect to competition and leaf‐mass increase in reproducing trees, growth allocation between height and stem diameter was examined for nonsuppressed reproducingAbies mariesiitrees in a subalpine forest in northern Honshu, Japan. The growth allocation was analyzed by dividing the relative growth rate of the stem volume into the relative contributions of height and stem‐diameter growth. During a 9‐yr period, height growth and seed‐cone production showed obvious annual variation, while stem‐diameter growth recorded moderate variation. For two of three years of seed‐cone production during the 9‐yr period, trees with larger seed‐cone production were associated with less height growth in the following year of seed‐cone production; however, there was no trend of height growth in the year of seed‐cone production. In the following year of mast seeding, trees with larger stem‐volume growth were associated with less height growth. This trend was also shown for the relationship between the cumulative stem‐volume growth during the 9‐yr period and growth allocation to height, suggesting that trees with a larger biomass increase depress the allocation of photosynthate to competition with a large expenditure for reproduction. In contrast to this, trees with a smaller biomass increase might allocate photosynthate to competition with surrounding trees. The results of this study suggest that an increase in reproductive organs during life history and annual variation in reproduction are closely associated with the growth patterns of the stem inA. mariesiitrees.
