OUTPATIENT UTILIZATION OF ANTIBIOTICIS IN THE REPUBLIC OF SRPSKA, IN 2007 AND 2008




Cytogenetic evidence for genome elimination during microsporogenesis in interspecific hybrid between Brachiaria ruziziensis and B. brizantha (Poaceae)

Microsporogenesis was analyzed in an interspecific hybrid between an artificially tetraploidized sexual accession of Brachiaria ruziziensis (R genome) and a natural apomictic tetraploid accession of B.brizantha (B genome).Chromosomes associated predominantly as bivalents.From this phase to the end of meiosis, chromosomes presented irregular segrega
