Abstract
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.
