During epidemiological survey for phytoplasmas in association with agricultural crops in Serbia, a new species of common weed has been detected to harbor phytoplasmas in Serbia. In 2010, a total of 38 samples of Picris ...
Fatty Acids of Some Moss Species from Germany
(Asian Journal Of Chemistry, Sahibabad, 2011)
The fatty acid composition of three mosses collected in Germany was preliminary analyzed by gas chromatography (GC-FID) and gas I chromatography-mass spectrometry (GC-MS) for the first time. It was found that Hypnum ...
Comparative research of accumulation of heavy metals in woody plants and herbs
(Parlar Scientific Publications (P S P), Freising, 2011)
