On the possible relationship between Kober stem grooving and grapevine virus A.

摘要: Investigations were carried out to establish possible correlations of two diseases the rugose wood complex, i.e. Rupestris stem pitting (RSP) and Kober grooving (KSG) with grapevine virus A (GVA) leafroll associated viruses I (GLRaV I) III III). To this purpose 84 clonal accessions different wine grape cultivars analyzed by ELISA indexing onto indicators Vitis rupestris , 5BB LN 33. The results obtained clearly indicated that none taken into consideration is apparently involved in etiology RSP. Conversely, a remarkably close association GVA KSG was discovered.
