Cotton bacterial blight caused by Xanthomonas citri subsp. malvacearum (Xcm) is one of the most widely distributed and devastating diseases of cotton (Gossypium spp.) worldwide. Twelve Xcm races have been described in the world, with their relative prevalence varying by country. This study aimed to determine the current frequency and distribution of Xcm races in Brazil. Leaves showing cotton blight symptoms were collected from 12 cotton producing areas in the states of Bahia, Goiás, Mato Grosso and Mato Grosso do Sul. A total of 92 isolates were collected from surveyed areas. Race identification was performed by injection of bacterial suspensions into 10 differential cotton cultivars (Acala 44, Stoneville 2B-S9, Stoneville 20, Mebane B1, 1-10B, 101- 102B, Gregg 8, Empire B4, PDX P4 and S-295). All Xcm isolates were characterized as race 18, indicating this to be the prevalent race in Brazil. |

BACKGROUND: Obtaining two or more successive annual vintages from the same vineyard is characteristic of regions with a tropical climate, such as the Submédio of the São Francisco Valley, Brazil. The present study aimed to characterize the chemical composition of grapes in four production cycles (i.e. two calendar years) when considering the interaction between cv. Syrah and two rootstocks. For a broad characterization, two methodologies for the extraction of phenolic compounds were used, as well as different methods of analysis. RESULTS: The results obtained showed that there was an influence of rootstock and harvest season. Grapes from vines grafted onto IAC 313 contained higher concentrations of total condensed tannins (skins) and flavanols than grapes from vines grafted onto 1103P.However, the grape samples fromthe vines grafted onto 1103P contained higher levels of monomeric anthocyanins than the grape samples fromthe vines grafted onto IAC 313. The first harvest seasonwas characterized by higher concentrationsof most phenolic compounds than the second harvest season. CONCLUSION: In the present study, it was possible to confirm that, in the semiarid region of Brazil, the interaction between the cultivar Syrah and the different rootstocks, as well as the climatic conditions in each harvest season, influenced the composition of the grapes, mainly in relation to phenolic compounds. © 2019 Society of Chemical Industry |
