英文摘要	In order to evaluate the effects of pollination on resource allocation in the marsh herb Sagittaria potamogetifolia, experimental manipulation of pollination efficiency on the pattern of resource allocation was accessed by the proportion of dry weight measurements of sexual, vegetative, and clonal organs. In trials where half of the flowers were pollinated, a significant increase of resource allocated to sexual production and decrease to vegetative production resulted compared to plants that received no pollination. In trials where pollination was 100%, these two reproductive components showed the same trend, but less dramatically. This may support the idea that the trade-offs would be more pronounced when the resource was scarce. Besides, a higher inflorescence production with a lower fruit reproduction occurred as a consequence of decreased pollination level. This increased inflorescence production may be a mechanism to promote outcrossing by enhancing floral attraction or by synchronizing reproductive activity with insect pollinators. Examination for possible trade-offs in resource allocation revealed that there was also a trade-off caused by pollination between fruits plus flowers and bulbils production, which might have detrimental effects on the survival of individuals and populations, but promotes outcrossing and genetic variability.
