Determination of Prunus necrotic ringspot virus (PNRSV) and Apple mosaic virus (ApMV) Infections on Rose Plants (Rosa spp.) in Konya Province

Abstract

Roses, which are known for their different colours and fragrances, have found a wide place in both aesthetic landscaping and industrial uses and have both economic and cultural value for our country. Prunus necrotic ringspot virus (PNRSV) and Apple mosaic virus (ApMV) are important plant viruses that cause significant infections in rose (Rosa spp.) plants and can negatively affect plant growth, flower quality and general health. No previous study has been conducted to detect virus diseases in rose growing areas of Konya province. Within the scope of this study, leaf, branch and flower samples were collected from 94 rose plants of different varieties showing symptoms similar to the symptoms of virus diseases such as mosaic, deformations, chlorotic patterns, chlorotic ring spots on leaves, color breaks and deformations on flowers from various rose growing areas in Konya province in 2023. Rose plant samples collected from parks and gardens were tested using the DAS ELISA method, a serological diagnostic method. It was determined that PNRSV was present in 12.76%, ApMV in 11.70% and PNRSV + ApMV mixed infection in 2.12% of the tested rose plant samples. The total infection rate in the province was determined as 24.46%. It is thought that the results obtained from this study will contribute to the literature on rose virus diseases and will be an important source of information for rose producers, agricultural engineers and plant pathologists in the region. In addition, in the control of these two virus diseases in roses, the issues that producers should pay attention to such as vector insect control to control the spread of viruses and the plant material used for vegetative propagation should be free of viruses were emphasized.
