Abstract

Broomrapes are the most difficult plant parasites to control among all biotic stresses affecting plants in the Mediterranean, Europe and Asia. Lentil is sensitive to broomrape (Orobanche crenata), which causes significant yield losses in this species around the Mediterranean region. Our study was aimed at the evaluation of antibacterial properties of Lens culinaris cv. ‘Sultan-1’ under drought stress and broomrape infection stress conditions. The antimicrobial activity of the ethanol extract of ‘Sultan-1’ was assayed against the test for microorganisms by methods of diffusion in agar and dilution in broth. The ethanol extracts from different studied treatments showed antimicrobial activities, with diameters of the inhibition zone ranging from 7 mm to 15 mm and from 2.5 to 20 μg mL-1, respectively. The highest antimicrobial activity against A. baumannii ATCC 19606 was demonstrated by the extract of ‘Sultan-1’ at combined stress (drought stress + broomrape infection) on the 1st day. Furthermore, the combined stress treatment promoted antibacterial effect against some Gram-negative bacteria on the 1st day.
