Grapevine leaf roll disease in Central Serbia

Abstract

Leaf roll is one of the most important virus disease (Grapevine Leaf roll Disease = GLD) of grapevines. It occurs in all of the major grape-growing regions of the world. GLD are a group of nine viruses called 'grapevine leaf roll-associated viruses' (GLRaV-1-9), that cause similar symptoms in infected grapevines. Samples were collected from 5 regions in Serbia, and from 18 grapevine cultivars during 2002, 2005, 2006 and 2007 and tested using ELISA test for detection GLRaV-1,2,3,5 and 7. Only GLRaV-1,2 and 3 were detected in investigated regions. GLRaV-1 was detected in all five regions, and GRLaV-3 wasn't detected only in Trstenik's vineyards. GLRaV-2 was the uncommon in Serbia. All investigated cultivars were infected by GLRaV-3.

Uvijenost lišća vinove loze (Grapevine Leafroll Disease = GLD) je najznačajnije virusno oboljenje vinove loze. Do danas je u svetu utvrđeno ukupno devet različitih izduženih čestica, nazvanih 'grapevine leafroll-associated viruses' (GLRaV-1-9), u biljkama obolelim od uvijenosti lista. U pet značajnijih vinogorja u Srbiji u periodu od 2002 do 2007 godine testirano je ukupno 18 sorti vinove loze na prisustvo GLRaV1,2,3,5 i 7 primenom ELISA testa. U Srbiji je identifikovano prisustva tri soja, i to GLRaV-1,2 i 3 , GLRaV-1, je dokazan u svih pet ispitivanih vinogorja, a GLRaV-3, nije konstatovan samo u Trsteničkom vinogorju. U ispitivanim vinogorjima u Srbiji, najmanje je zastupljen GLRaV-2. Sve sorte kod kojih je bilo dokazano prisustvo GLRaVs bile zaražene u svim slučajevima GLRaV-3.
