ABSTRACT.
Brown rot can cause dramatic economic impacts on the commercial production of several Prunus species, including peach, nectarine, plum, apricot, cherry and almond, in most producer countries. In Brazil, this disease is caused by Monilinia fructicola. The objective of this work was to estimate the genetic parameters for brown rot resistance in 144 accessions from the germplasm bank of Embrapa Clima Temperado. Fruits of each accession were harvested at the firm ripe stage. Prior to inoculation, twnety fruits per genotype were disinfected by immersion in a 70% v/v alcohol solution, followed by a three minute immersion in a 0.5% v/v NaClO solution, and rinsing in distilled water. The inoculation was made by deposition of a 10 μL drop with 2.5×104 spores mL‑1 of M. fructicola, on the fruit surface that was wounded with a microsyringe. Inoculated fruits were incubated at 25±1°C and 75% relative humidity for 72 h. The samples were evaluated for disease severity (average diameter of lesions and sporulation). Broad sense heritability estimates for lesion and sporulation diameter was 50 and 13%, respectively. The coefficient of variance was 46% for sporulation diameter and 20% for lesion diameter. The studied population exhibited genetic variability and therefore potential for breeding. 'Bolinha', 'Marfim', 'Jade', 'Dourado II' and selections SB9, Cascata 1281, Cascata 967, SB25, Conserva 1904, Conserva 1844 and Cascata 657 showed higher resistance than the other accessions.

Abstract:
Pre-slaughter fasting duration affect blood parameters related to stress and metabolism, decrease live and carcass weights and impact beef quality of cattle. In three experiments, 1100 steers and heifers, finished on feedlot or on pasture, were evaluated to assess the influence of the site and duration of fasting before slaughter on physiological, carcass and meat quality traits. Cattle were allocated to one of two fasting duration - long (23?29 h) or short (2?6 h) ? and to one of two sites of fasting? farm or abattoir. All animals had access to water ad libitum until slaughter, except during transportation. Cattle were assigned to two (long fasting on abattoir/normal lairage time, short fasting on farm/minimal lairage time) or three (long fasting on abattoir/normal lairage time, short fasting on farm/minimal lairage time, long fasting on farm/minimal lairage time) treatments. Seventeen slaughters were considered in a randomized complete block design. There was no effect of the site of fasting on any variable. Cattle with short fasting duration had higher carcass weights and water consumption than those under long fasting duration. Haematocrit, globulin, total protein, and lactate dehydrogenase at the time of slaughter increased with fasting duration. There was no effect of the duration of fasting on blood ions, meat quality traits, urine pH, liver weight and volume, and skin dry matter. A reduction in the fasting duration returned to farmers and abattoirs 1.2% additional kilograms of carcass, suggesting an improvement in animal welfare according to a better hydration level of cattle at the time of slaughter.
