Abstract EN

A study was conducted at Al-Muturki village in Lattakia Governorate during 2019/2020 growing season to investigate the effect Cucumber mosaic virus (CMV) infection on the proline and hydrogen peroxide (H2O2) content of four pepper hybrids (Taline F1, Amani F1, Harek F1 and Marvilo F1) at three periods post viral inoculation (15, 30 and 45 days).

The experiment was carried out by using complete randomized block design with 8 treatments and 8 replicates per treatment.

The results showed that the viral infection affected the proline and hydrogen peroxidase content 15 days after virus inoculation.

The highest effect of the viral infection was at 30 days after virus inoculation, where the values of proline and hydrogen peroxidase of the infected pepper hybrids significantly increased compared to control plants.

However, 45 days after virus inoculation, the effect of viral infection decreased with plant age.
