The mycoflora of barley - the varieties extension certificated at ARDS – Teleorman

Abstract

Knowing the health of the barley caryopsis holds an important place in this plant’s pathology and help the establishment of its control measures, with major consequences in obtaining a high production in terms of quantity and quality. The researches on barley seeds micoflora were carried out in "in vitro" conditions and the biological material used was consisted of untreated barley caryopsis from several varieties: Andrei, Mareşal, Mădălin, Compact, Amical and Dana. The micromycetes’ identification realised by successive isolation and sub-culturing on them in culture medium PDA (Potato Dextrose Agar). The pathogens were incubated in thermostat at a temperature of 220C. The identified micromycetes belonged to the next classes : Alternaria sp.- 45%, Drechslera sp.-31%, Macrosporium sp-10%, Fusarium sp.-5%, Rhizopus sp.- 4%, Penicillium sp.- 2%, Aspergillus sp-3%. From the analyzed varieties the most affected were: Mareşal, Mădălin and Compact. The micoflora detected on the analyzed barley caryopsis did not inhibit their germination process.
