AN INVESTIGATION OF INTRASPECIFIC GENOTYPIC VARIATION OF BOLBOSCHOENUS MARITIMUS (ALKALI BULRUSH)
Previous research suggests intraspecific variation of traits may be driving high functioning in species limited ecosystems. If genotypic differences influence functional traits, then this relationship could explain the high functioning of species-poor wetland systems. We examined trait variation within and among different genotypes of the wetland plant Bolboschoenus martimus. We collected rhizomes from wetlands in Montana, Arizona, and Utah and grew 5 genotypes from these various sites in a common garden experiment for 22 weeks. We measured above-ground and below-ground traits which include maximum vegetative height, stem density, specific leaf area, relative growth rate, number of inflorescences, above- and below-ground carbon to nitrogen ratio, number of new rhizomes, and biomass. We found trait variation among genotypes was dependent on the trait examined. Specifically, we found stem density and number of inflorescences were significantly different between genotypes. Our results document intraspecific variation is an important determinant of functional traits in B. martimus. Our results also suggest intraspecific diversity could be a major driver of high functioning in wetland ecosystems.
