Abstract
The field experiment was conducted at an Al-Muturki village in Lattakia Governorate, during 2019/2020 growing season in the autumn knot and the experiment was repeated in the spring loop to study the effect Cucumber mosaic virus (CMV) infection on indicators of vegetative growth of four hybrids of pepper plants Taline F1, Amani F1, Harek F1 and Marvilo F1 at three times after viral infection 15, 30, 45 days. The experiment was carried out using the randomized complete block design with 8 treatments and 4 replicates per treatment. The results showed in autumn and spring planting that, the symptoms of infection with Cucumbr mosaic virus appeared on all hybrids of peppers, infected with the virus, the severity of the symptoms varied on hybrids after 15, 30, 45 days after infection. Infection with Cucumber mosaic virus affected on the vegetative growth indicators (apparent symptoms, the number of leaves, number of branches and plant height) after 15 days of viral infection, the highest effect of the viral infection was 30 days after infection, Where the values indicators of vegetative growth of the hybrids of infected peppers decreased by significant differences compared to control plants. As for 45 days after infection with the virus, the effect of the viral infection decreased with the age of the plant. On the three dates, the decrease in the values of indicators of vegetation in spring loop higher than the decrease in the values in autumnal knot.
