Bakteriofagi u zaštiti bilja
(Univerzitet u Novom Sadu - Poljoprivredni fakultet - Departman za zaštitu bilja i životne sredine "dr Pavla Vukasovića", Novi Sad, 2008)
Bakteriofagi predstavljaju posebnu grupu virusa, čiji su domaćini bakterije. Odmah nakon otkrića, s početka prošlog veka, privukli su pažnju svojom sposobnošću da parazitiraju ćelije bakterija i tako utiču na njihovu ...
Comparison of light and fluorescence microscopy for xylem analysis in tomato pedicels during fruit development
(Wiley, 2008)
The xylem hydraulic connection between shoot and fruits has previously been investigated, but contradictory conclusions were drawn about the presence of a flow resistance barrier in the pedicel. In this paper we were ...
