متن کاملSpecies relationships in Lactuca s.l. (Lactuceae, Asteraceae) inferred from AFLP fingerprints.
An AFLP data set comprising 95 accessions from 20 species of Lactuca s.l. (sensu lato) and related genera was generated using the primer combinations E35/M48 and E35/M49. In phenetic analyses of a data subset, clustering with UPGMA based on Jaccard's similarity coefficient resulted in the highest cophenetic correlation, and the results were comparable to those of a principal coordinates analysi...
متن کاملA morphometric analysis of infraspecific taxa within the Ixeris chinensis complex (Asteraceae, Lactuceae)
Morphometric methods were used with 40 morphological characters from each of 110 individuals collected from 11 populations of the Ixeris chinensis complex to test hypotheses regarding infraspecific taxa. Individuals of the nearest relative I. tamagawaensis were included as an outgroup. To utilize structual associations of the original data and the cumulative values of character variation, a mod...
