| Abstract/Contents: | "Variation in morphology and energy allocation pattern to propagule output was analyzed in six Poa annua L. populations from paddy fields, upland fields and pathways in two locations to determine the adaptive strategies of the species to their habitats. There was great variation among populations in seed number per plant and reproductive allocation (RA) or plant biomass. The number of seeds in all three populations from one of two locations increased in response to RA. Seed numbers of the paddy and upland field populations from the other location were independent of both RA and plant biomass. The remaining pathway population increased the seed number in response to both RA and plant biomass. Paddy field plants headed slowly with a large number of leaves on the main stem. They produced large and heavy seeds and large plant biomass, causing rather low RA. In contrast, individuals from upland fields flowered quickly with a small number of leaves, putting out small and light seeds from their small plant biomass, which resulted in relatively high RA. Pathway plants showed intermediate characteristics between paddy field and upland field plants. The reproductive traits of upland field populations seem adaptive to the irregular ploughing in upland fields, and paddy field populations appear to be adaptive to the competition from other weeds or crops." |
