Contenido :  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.

Contenido :  ABSTRACT.- Controlling a pest species raises questions about the harmful effects its eradication could cause in ecosystems. Currently, in Uruguay are being analyzed strategies to eradicate the New World Screwworm (NWS), Cochliomyia hominivorax (Diptera: Calliphoridae), an obligatory ectoparasite that causes myiasis in warm-blooded vertebrates, including humans. The loss of a species implies a risk of secondary extinctions and cascading effects that depend on the ecological function of the species and the capacity of the rest of the species with which it interacts to compensate for its loss. To assess the ecological impact of the NWS eradication, we analyzed its ecological redundancy, its effect as an indirect regulatory agent for other species, and its participation in critical ecosystem functions. We conclude that the NWS presents high functional redundancy in most ecological interactions. It does not play an essential role as a regulatory agent of other species and does not play an important role in critical ecosystem functions. Without ignoring the information gaps that certainly exist about the ecological interactions network of the NWS in Uruguay, we estimate that its eradication is unlikely to cause secondary extinctions or cascading effects in the networks it integrates. In order to timely detect possible impacts during the course of the program, it is recommended to monitor the ecosystems using indicators related to direct and indirect partners in the ecological inte... Presentar Todo
