摘要

达到最高的植物总生物量[0.28 ?0.01 g(平均?开花时。从开花到分果皮成熟，植物总生物量减少。连续两年，分配给根系的生物量占总生物量的比例(- 22.2 ?2.9%)，在5个生长阶段均低于其他营养结构。生物量分配在生殖生长阶段的变化只发生在地上结构中。尽管生殖结构的质量与植物的营养质量密切相关，但不同年份间回归斜率的差异表明，生殖分配百分比的队列间差异并不能完全由植物的总体大小来解释。

Ecological life cycle of Chaerophyllum procumbens variety shortii (Apiaceae), a winter annual of the North American Eastern Deciduous Forest

reached highest total plant biomass [0.28 ? 0.01 g (mean ? SE)] at flowering. Total plant biomass decreased from flowering to mericarp maturity. In two successive years, the proportion of total biomass allocated to roots (- 22.2 ? 2.9%) at five growth stages was less than that allocated to any other vegetative structure. Changes in biomass allocation during reproductive growth stages occurred only in above-ground structures. Although mass of reproductive structures was strongly correlated with plant vegetative mass, differences in slopes of the regressions between years indicated that between cohort differences in percent reproductive allocation were not completely accounted for by overall plant size.

期刊介绍： The Journal of the Torrey Botanical Society (until 1997 the Bulletin of the Torrey Botanical Club), the oldest botanical journal in the Americas, has as its primary goal the dissemination of scientific knowledge about plants (including thallopyhtes and fungi). It publishes basic research in all areas of plant biology, except horticulture, with an emphasis on research done in, and about plants of, the Western Hemisphere.
