Phytoplasmas are group of phytopathogens that are commonly transmitted by insects and reside in the phloem causing reduction of yield and good quality. Stolbur phytoplasma is associated with diseases of hundreds of plant species including pepper, tomato and potato from Solanacae family, with great economic importance. Recent multilocus genetic analyses on leaves collected from pepper plants from localities on the territory of the Republic of North Macedonia, confirmed stolbur infection accompanied with decreased chlorophyll content and increased carotenoids level. Leaves of two pepper varieties from different localities were investigated - sweet red pepper, variety Kurtovska kapija Capsicum annum var. annuum, (Strumica region), and Capsicum annuum var. cerasiforme (Kocani region). As a continuation of this research, in the present study asymptomatic leaves (without chlorosis) from the same plants were collected and analysed for systemic response in respect to pigment content, reducing sugars level and antioxidant parameters. Leaves from uninfected control plant from both pepper varieties, were compare with asymptomatic leaves from stolbur affected plants.
