亚洲远东北方落叶林的林下植被以巨大的夏季绿色草本植物为特征。我们研究了落叶林中6种巨大的夏绿草本植物在光照条件下的高度生长、叶片积累、光合特性、日净同化和地上部分干物质分配模式。5种植物的株高、叶片数和单株总叶面积均随郁闭度的增加而增加。亚种orientalis Kitam.，甘肃蓟，甘氏丝瓣兰Filipendula kamtschatica（Pall.）Maxim. F. kamtschatica，大麻叶千里光Senecio cannabifolius Less.，和宽叶荨麻（Urtica platyphylla Wedd.）在整个生长季节中持续产叶，而一个物种（藜芦L.亚种oxysepalum Hulten）产叶早，产叶多在郁闭开始前完成。最大光合和暗呼吸速率在所有物种的季节性下降。物种
Understory vegetation of northern deciduous forests in far eastern Asia is characterized by giant summer-green herbs. We examined the patterns of height growth, leaf accumulation, photosynthetic characteristics, daily net assimilation, and dry matter allocation within aboveground parts of six giant summer-green herbs with reference to light conditions in deciduous forests. Plant height, leaf number, and total leaf area per plant increased with progressing tree-canopy closure in five species (Cacalia hastata L. subsp. orientalis Kitam., Cirsium kamtschaticum Ledeb., Filipendula kamtschatica (Pall.) Maxim. f. kamtschatica, Senecio cannabifolius Less., and Urtica platyphylla Wedd.) that had continuous leaf production throughout the growing season, whereas one species (Veratrum album L. subsp. oxysepalum Hulten) with early leaf production, completed leaf production mostly before the beginning of tree-canopy closure. Maximum photosynthetic and dark respiration rates decreased seasonally in all species. Species...
