Uticaj ugljenika i azota na porast izolata Colletotrichum spp

Abstract

In Serbia, the occurrence of anthracnose on pear, apple, sour cherry, and tomato fruits has been recorded during the last several years. Colletotrichum spp. were isolated from all diseased fruits. Twenty monoconidial isolates were selected for comparative studies, and the reference strains of C. acutatum (CBS 294.67) and C. gloeosporioides (CBS 516.97) were used as a control. The physiological studies have included the investigation of the effect of different sources of carbon and nitrogen on growth of C. acutatum and C. gloeosporioides. The results indicated that carboxymethyl cellulose was the most appropriate source of carbon for the growth of isolates of Colletottrichum spp. Of the three nitrogen sources studied, the best growth of all tested fungi was recorded on the media with casein hydrolysate.
