F. Gonzalezandres et al., CARYOPSIS ISOENZYMES OF ECHINOCLOA WEED SPECIES AS AN AID FOR TAXONOMIC DISCRIMINATION, Journal of Horticultural Science, 71(2), 1996, pp. 187-193
The number of recognized taxa within the genus Echinocloa Beauv. varie
s from one author to another. As the morphological variation is quite
continuous, it is difficult to establish different taxa. In this work,
caryopsis morphometry and isoenzymes were used as an aid for the disc
rimination of the eastern Spain species. The multivariate analysis of
isoenzymes clearly defines three species: E. colonum, E. crus-galli an
d E. oryzicola and a group formed by E. hispidula and E. oryzoides in
which the variability between populations of E. hispidula is higher th
an the variability between both taxa.
