Abstract:Bromus auleticus is a cool season perennial C3 grass, recognised as a forage plant genetic resource and used for native grasslands restoration. It is native to the campos biome, found in southern Brazil, Uruguay and central Argentina. Its forage yield is comparable with tall fescue. Seed dormancy is a problem to evaluate germination and for commercialisation of this species. Using four recently harvested seed lots of three different genotypes, we tested six different treatments to release dormancy: a control (mean germination 52%); 0.05 and 0.1% gibberellic acid; KNO3; pre-chilling + KNO3; and pre-chilling (mean germination across seed lots and treatments, 87%). Pre-chilling + KNO3 and pre-chilling were the best treatments to break dormancy, with mean germination times (MGT) reduced to half (8.7 and 9.3 days-1) that of the untreated control (19.2 days-1). The treatment with KNO3 alone did not yield uniform results across seed lots; when combined with pre-chilling, final germination did not increase but showed more consistent results. The use of 0.05% gibberellic acid was less efficient than pre-chilling to reduce the MGT of 17.2 days-1, but it could be considered as an alternative treatment for seed lots in which the germination results are needed fast and has the additional advantages of avoiding exposing seeds to cold stress. Furthermore, if seeds are contaminated with fungi, it reduces growth time and contamination effects. |

ABSTRACT - Although the ancient Vitis vinifera Tannat variety is virtually unknown in the international wine market, the strategy to promote it as the Uruguayan emblematic grape variety is starting to become successful in the red wines market. This paper presents a summary of the latest research and developments performed in
Uruguay with Tannat since the late 1970s, its origin and production statistics. As an expression of the state-of-the-art viticultural technology developed in Uruguay for this variety during the last ten years, the chemical characterization of the polyphenolic and aroma profiles, typical for this variety, is also presented. The high
polyphenolic content of this V. vinifera variety, when compared to other red grapes, confer its wines a high free radicals scavenging activity. Furthermore, from the
winemaking point of view, some New World wine-producing countries have planted this grape to blend it with their own varieties, with the purpose of adding more
structure and aging potential to their premium red wines. |
