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 theTabuenca test. Chilling accumulation was computed using four different chilling hour (d+ 7.2 ºC and d+ 11 ºC) models; and chill units using the Low Chill model and theTaiwan 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 d+ 7.2 °C, d+ 11°C, or Taiwan model) is suitable to classify comparatively dif ferent cultivars, but none is accurate enough to conclude on the adaptation of a given cultivar to a specific site. Using hours of temperatures d+ 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 |

A new procedure for the determination of As, Cd, Cr, Cu, Hg, Pb, and Zn in fish and meat (bovine and ovine) samples by microwave-induced plasma optical emission spectrometry (MIP OES) was developed. The procedure is based on separation and preconcentration of analytes by solid-phase extraction (SPE), composed from the functionalization of silica with p-aminobenzoic acid (PABA-MCM-41). Factors that directly affect the SPE procedure as pH, buffer concentration, sample flow, and elution flow were evaluated through a factorial design (24). The optimized conditions employed at the proposed procedure were as follows: pH 9.5, 0.01 mol L−1 borate buffer concentration, sampling, and 6.0 mL min−1 of elution flow. Linear models were treated regarding the weighted regression, an optional strategy of the equipment, the weighted fit. The proposed procedure provides limits of quantification (LOQ) of 9.6, 2.8, 0.1, 0.2, 1.5, 13.3, and 3.9 μg g−1 for As, Cd, Cr, Cu, Hg, Pb, and Zn, respectively. Accuracy was assessed from the analysis of the certified reference materials (CRM) of dogfish liver (DOLT-5, NRC) and bovine liver (1577c, NIST), and a reference material of bovine liver (RM-Agro E3001a, EMBRAPA). The procedure was applied in local market meats (bovine and ovine) and fish (tilapia) samples, and it showed adequate for the determination of As, Cd, Cr, Cu, Hg, Pb, and Zn by MIP OES. |
