Abstract
Genus Alternaria represents one of the most important pathogens of Apiaceae family. Alternariose symptoms may develop on foliage causing leaf spot, necrosis and eventually drying and black root. Celery plants with characteristic symptoms were collected during 2012 and 2013 in Serbia. The preliminary identification was done by analysis of morphological characteristics of conidia. After identification cultural characteristics, growth rate and spore morphology were examined and compared based on influence of ecological factors such as nutrient medium, temperature, pH value of the medium and light quality.
Vrste roda Alternaria predstavljaju jedne od najznačajnijih gljiva patogena familije Apiaceae. Promene koje izazivaju na biljkama domaćinima su mrka trulež korena, pegavost lišća, sušenje listova i lisnih preteljki. Tokom 2012. i 2013. godine na teritoriji Srbije, prikupljeni su uzorci celera sa karakterističnim simptomima pegavosti lišća i sušenja listova. Identifikacija izolata je izvršena analizom morfoloških karakteristika spora gljive. Nakon identifikacije izvršena su uporedna proučavanja uticaja različitih hranljivih podloga, temperatura, pH vrednosti podloga i kvaliteta svetlosti na morfološke karakteristike izolata, porast kolonija i morfologiju spora.
