| Abstract/Contents: | "A field trial was initiated to examine the range of inter- and intraspecific variations in morphological and phonological traits with five different accessions of smooth and large crabgrass. In addition, a controlled environment study was conducted to determine the phenotypic plasticity among the accessions of both species in response to 4 daily temperature differentials. In the field experiment, significant inter- and intraspecific variations of smooth and large crabgrass were observed in morphological traits such as leaf length and width. However, most phonological traits were not substantially different between the species and among the accessions of each species. The first seedling emerged at the same time, requiring 9~10 days, regardless of the accessions and species. In a controlled environment study, all accessions of each species responded similarly to the 4 temperature differentials in seeding emergence, indicating seedling emergence was not a plastic trait. These results suggest that predicting crabgrass emergence could be independent of geographical regions in the US." |
