achenes, C. arvense, diversity, flowerheads/ capitula, male and female clones.
The species has an important presence in crops (Everitt et al., 2007). It’s occurs in- micro (asexually) by forming clones with different densities (Donald, 1994), and in-macro (sexually) by fruits with conquering new lands. The sexed propagation type is dioecious, with the presence of both female plants and those male. To express existent ecotype weed in the Southern Highlands area, they have made some determinations of variability. Thus, the male heads had in flourished time average size 14.6-15.1 mm / 7.0-7.5 mm, with or without fruits (achenes). Females flowerhead (capitula) were 25.4 mm / 8.8 mm and formed 22 achenes. Female clones had fruits 2.29 mm length, thickness 0.65 mm and 20.5 mm pappus. Some correlations obtained were positive and significant: between flowerhead dimensions r = 0.375*** and 0.265 ** in male populations and r = 0.278 * the female population. Negative correlation was obtained between the sizes of the female clones fruits, r = -0.037. The present study demonstrated cross-type structure evolved in these conditions and wide possibilities that it has spread throughout the agricultural field.
