THE BOLIVIAN SPECIES OF VERNONIA

Evaluation of the Agronomic Performance of Vernonia (Vernonia galamensis) Germplasm

Cytotaxonomic studies in six species of Vernonia (Asteraceae: Vernonieae)

In this report, we describe a mitotic analysis (Giemsa technique) of six species of the genus Vernonia sensu Baker (Asteraceae, Vernonieae, section Lepidaploa) in order to assess the validity of maintaining this genus (sensu Baker) or dividing it into several lesser genera (sensu Robinson). Specimens of the seven species were collected in “cerrado” and “campo rupestre” areas in the states of Sã...

Three new species of Eimeria from Bolivian marsupials.

Faecal samples collected from 300 Bolivian marsupials (Didelphimorphia: Didelphidae) between 1984 and 1993 were examined for coccidian parasites. Sporulated oocysts were present in the faeces of 50 (17%) marsupials representing 11 genera and 22 species. Three new species of Eimeria are described and named from six host species. One species occurred in Marmosops dorothea, Monodelphis domestica a...

Influence of inter and intra row spacing on growth and yield of Vernonia (Vernonia galamensis Cass.)

Vernonia galamensis Cass is a huge potential industrial crop with very high content of vernolic acid in the seed oil. The experiment was carried out to determine the effect of inter- and intra- row spacing on the yield and yield related traits of Vernonia galamensis Cas.The experiment was conducted for two years during 2014-2015 on experimental field of Wondo Genet Agricultural research center,...

Phytochemical screening and antibacterial activities of Vernonia ambigua, Vernonia blumeoides and Vernonia oocephala (Asteraceae).

Some Vernonia species (Vernonia ambigua, Vernonia blumeoides and Vernonia oocephala) used in Northern Nigerian traditional medicine, were subjected to phytochemical screening using standard procedures. The antibacterial activity using the disc diffusion method as outlined by the NCCLS was carried out on Klebsiella pneumoniae, Streptococcus pyogenes, Staphylococcus aureus, Corynbacterium ulceran...
