Grapevine fanleaf degeneration disease (GFDD) in vineyards in the Odesa region, diagnosis, prospects for its recovery by heat treatment

Карантин і захист рослин
Goal. Grapevine fanleaf virus (GFLV) is one of the main causes of grapevine fanleaf degeneration disease (GFDD) and is present in almost all areas where grapevine (Vitis spp.) is cultivated. In this work, we ascertained the presence and spread of GFLV in

In vitro propagation of Vitis vinifera L. cv. ‘Monastrell’

Electronic Journal of Biotechnology, 2017
Background: A protocol for the micropropagation of the grape (Vitis vinifera L.) cultivar ‘Monastrell’ was developed. Initial plant material was obtained from the sanitary selection of grapevine plants performed by real-time RT-PCR to confirm the absence

The sustainability of old grapevine mother plants in relation to new mandatory diagnostic tests for virus control

Advances in Horticultural Science, 2012
In 2011, the methods to perform phytosanitary tests to check for viruses in grapevine nurseries were reassessed and new regulations were defined (DM 13 December 2011).

Research Note virus transmission by grape phylloxera (Daktulosphaira vittfoliae Fitch)

International Journal of Horticultural Science, 2004
Grape phylloxera (Daktulosphaira vitifoliae FITCH) infests immature roots of both Vitis vinifera L. and phylloxera resistant rootstocks. A capability to transmit viticultural viruses would make grape phylloxera a phytosanitary threat even under ...

The demonstration of the GFLV Nepovirus isolates on naturally infected grapevine cultivars and evaluation of variability within genome region encoding movement protein

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2011
In this work, the infection of Grapevine fanleaf virus (GFLV) disease was described on the base of symptomatic differences within eight grapevine plants of six grape ciltivars with positive tests on GFLV. Among them, cultivars Kodrjanka, Pamjati Negrula,

Suitability of the date of grapevine tissue sampling for tests of GFLV and ArMV presence using ELISA method

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2007
Grapevine fanleaf virus (GFLV) and Arabis mosaic virus (ArMV) are two important agents from the Nepoviruses genus. At present, serodiagnostic method is one of routine methods of virus pathogens testing also in grapevines.

Occurrence of viruses and Xiphinema spp. in vineyards of the greek islands of Paros and Lemnos

Phytopathologia Mediterranea, 2001
A survey was carried out during 1997–2000 in order to determine the incidence of grapevine viruses and their associated nematode-vectors in Paros and Lemnos, the two main islands of the Aegean sea producing V.Q.P.R.D. wines.
