ABSTRACT.- The adaptation of temperate fruit crops is a challenge being increased by the global warming. Chilling requirement is a key factor for adaptation. The objective of this study was to estimate the chilling requirement of peach cultivars BRS Bonão, Esmeralda, Granada and Eragil, using the Tabuenca test. Chilling accumulation was computed using four different chilling hour (? 7.2 ºC and ? 11 ºC) models; and chill units using the Low Chill model and the Taiwan model. The fresh bud weight and bud water contents were also evaluated. The Tabuenca test (based on differences in bud´s dry weight) showed a fairly good efficiency for estimating the end of dormancy in peach. However, under mild winter conditions, it is better to use fresh bud weights. Either one of three chilling accumulation computation models (temperature ? 7.2 °C, ? 11°C, or Taiwan model) is suitable to classify comparatively different cultivars, but none is accurate enough to conclude on the adaptation of a given cultivar to a specific site. Using hours of temperatures ? 11 ºC: ?BRS Bonão? needed around 180 hours for dormancy release; ?Esmeralda? around 250 hours; ?Granada? between 300 and 400 hours, and ?Eragil? more than 500 hours. |

Abstract: Context. Uninterrupted nutrient uptake and the use of bulls with high genetic merit for carcass traits may increase the likelihood of producing high-quality retail cuts for different markets. Aim. The objective of this experiment was to evaluate the combined effects of level of nutrition during the 104-day post-weaning winter period (WADG; low-L: 0.2 vs high-H: 0.6 kg/calf per day) and level of expected progeny differences (EPD) for ribeye area (REA; high-H or average-Av) on carcass traits and retail cuts of Hereford steers. Methods. Three crops of calves (n = 317) were selected according to REA (H-REA vs Av-REA), blocked for weaning weight (WW) and randomly allotted to one of the two WADG treatments (L-WADG vs H-WADG) for 104 days. Experimental design was a completely random block and the treatments were the combination of two factors (2 · 2). After winter (L-WADG and H-WADG groups), all calves grazed on improved pastures (herbage allowance: 5% of liveweight (LW) per day). The finishing was done on a feedlot and started when the group average of animals reached a full LW (FLW) of 350 28 kg. Cattle were harvested at a constant final FLW of 525 40 kg. Key results. No interaction was observed (P > 0.05) between WADG and REA for carcass traits. Animals with H-WADG presented higher (P < 0.05) hot carcass weight (HCW) and dressing-out (%) than L-WADG. High REA and H-WADG steers showed higher weight (kg) in the rump and loin, striploin, sirloin, and lean component in the pistola cut (P < 0.01). Likewise, H-REA and H-WADG presented a greater proportion of rump and loin (P < 0.01) and lean (%) (P < 0.05) than Av-REA and L-WADG, respectively. Conclusions. The combined effects of greater post-weaning winter gains and high REA EPD allow slaughter of younger steer with greater lean proportion and retail cuts. Implications. No interaction between the REA and WADG allows producers to plan economic benefits through a higher WADG in the first winter phase as well as using superior bulls for carcass traits to achieve heavier retail cuts.
