Essential oil composition of different coriander (coriandrum sativum l.) Accessions and their influence on mycelial growth of colletotrichum spp.

Abstract

Six coriander accessions of different origins were grown on an experimental field in Mogorin, Serbia during 2014. The GC/MS analysis of the essential oil showed that the major components in all samples were linalool (69.3-72.0%), gamma-terpinene (6.0-9.6%) and alpha-pinene (6.7-8.2%), while other compounds were present at less than 5%. Antifungal activity of coriander oils against two phytopathogenic fungi from Colletotrichum genus (C. acutatum and C. gloeosporioides) was evaluated using the inverted petriplate method. Experiments show that coriander essential oil has antifungal properties against the apple bitter rot pathogens from Colletotrichum genus, but only at higher application rates (>= 0.16 mu l/ml of air). According to the obtained data, it can be concluded that tested coriander accessions differ in essential oil content and composition, as well as in influence on mycelial growth. Coriander essential oil has potential for being applied as a biological control agent against these two fungi from Colletotrichum genus.
