Chromosome polymorphism and cytotype establishment in Bidens pilosa (Asteraceae)
(Faculty Press, 1999-01-01)
Chromosome evolution, in the Bidens genus, was by polyploidy mechanisms. The basic number to the genus is X = 12 chromosomes, as all the Fitchinae subtribe. The association of chromosome number and environment in these ...

(Inst Tecnologia Parana, 1993-06-01)
The germination of seeds of Bidens pilosa L. colected at different places was analyzed by dose-response curves for induction and reversion of germination in seeds pre-incubated at 25 degrees C or 36 degrees C during 24 ...

Achene dimorphism in Bidens pilosa L. (Asteraceae) as determined by germination test
(Brazilian Archives of Biology and Technology, 1998-06-01)
The germination of achenes of Bidens pilosa L. was analyzed during the life span of the mother plant. Decrease in the range of achene size was monitored until the senescence of the mother plant when the shortest achenes ...
