Efeito do porta-enxerto e da época de poda na duração das fases fenológicas e no acúmulo de graus-dia pela videira 'Niagara Rosada'

It was evaluated the influence of rootstocks 'IAC 766', 'IAC 572', 'IAC 313', 'IAC 571-6' and 'Ripária do Traviú' and the pruning periods in the duration of phenological stages and in the accumulation of degree-days on grape 'Niagara Rosada' .The experiment was conducted in Louveira, SP. The treatments consisted of five rootstocks and three times of pruning, the experimental design being used in a completely randomized split plot with five replications, and plots represented by rootstocks and the subplots were pruning. After pruning the grapevine, were realized evaluations for phenological stages, using the criterion of Eichhon e Lorenz (1984). ). In three seasons of pruning, based on phenological stages, it was calculated the length of the periods: pruning to budding, pruning to the beginning of the flowering, pruning to the beginning of fruiting, pruning to beginning of ripening of the bunches, pruning the beginning of the harvest. Taking as a basis the cycle length of the vine and the average daytime temperatures, it was calculated the accumulation of degree-days. Data were submitted to ANOVA and Tukey test at 5% significance level. It was obtained in the summer pruning the reduction in duration of the phenological stages of 'Niagara Rosada' grafted on the rootstock 'Ripária Traviú'. The longer duration of the cycle and accumulation of degree-day of 'Niagara Rosada' cultivar were obtained with the rootstocks 'IAC 572' and 'IAC 313' pruning in the winter.

Épocas e extensões do período de convivência das plantas daninhas interferindo na produtividade da cultura do milho (Zea mays)

Q field experiment was carried out at the Gralha Azul Experimental Farm/PUCPR, in the municipality of Fazenda Rio Grande-PR, to evaluate the effect of different times and coexistence extension periods of weeds interfering in corn yield. The experiment was arranged in a complete randomized complete block design and the treatments in a 4x5+2 factorial, with four replications. The treatments were as follows: four initial weed control periods (0-0, 0-7, 0-14 and 0-21 DAE) and five restarted weed control periods until the harvest (28, 42, 56, 70 and 84 DAE) and two checks, weedy and weed-free. The experiment was carried out under a no-till system. The period prior to weed interference (PBWI), the start of the critical period of weed interference (CPWI) and the infesting community were evaluated. When the initial weed control period was 0-0 day, the PPWI was at 9 DAE of corn; however, with increasing initial weed control periods (0-7, 0-14 and 0-21 DAE) the period prior to weed interference inncreased in relation to 0-0 day of the initial weed control, evidencing the existence of PPWI-S of 17, 24 and 28 DAE of corn, respectively. Thus CPWI initiates at the end of PPWI-S, the period when weed control is indispensable to prevent a significant reduction in corn yield. Coexistance with the weeds throughout the crop cycle reduced yield in 15%, compared to the weed-free check. Nine species of seven botanical families were assessed in the infesting community. Reduced density and dry mass were verified in the weeds that coexisted with corn, compared to those that grew without it, thus evidencing a suppressive effect of corn over the infesting plants.

Effects of flunixin meglumine administration on physiological and performance responses of transported feeder cattle

The objective was to evaluate the effects of flunixin meglumine administration on physiological and performance responses of transported cattle during feedlot receiving. Forty-five Angus x Hereford steers were ranked by BW on d 0 and assigned to 1 of 3 treatments:1) transport for 1,280 km in a commercial livestock trailer and administration of flunixin meglumine (1.1 mg/kg BW; intravenous) at loading (d 0) and unloading (d 1; FM), 2) transport for 1,280 km in a commercial livestock trailer and administration of 0.9% saline (0.022 mL/kg BW; intravenous) at loading (d 0) and unloading (d 1; TRANS), or 3) no transport and administration of 0.9% saline (0.022 mL/kg BW; intravenous) concurrently with loading (d 0) and unloading (d 1) of FM and TRANS cohorts (CON). Upon arrival and processing for treatment administration on d 1, steers within each treatment were ranked by BW and assigned to 15 feedlot pens (5 pens/treatment, 3 steers/pen). Full BW was recorded before (d -1 and 0) treatment application and at the end of experiment (d 28 and 29) for ADG calculation. Total DMI was evaluated daily from d 1 to 28. Blood samples were collected on d 0 (before treatment administration), 1 (after unloading but before treatment administration), 4, 7, 10, 14, 21, and 28. Body weight shrink from d 0 to 1 was less (P < 0.01) in CON vs. FM and TRANS but similar (P = 0.94) between TRANS and FM. Mean ADG was greater (P <= 0.04) in CON vs. FM and TRANS but similar (P = 0.69) between TRANS and FM. No treatment effects were detected on DMI, but CON had greater G:F vs. TRANS (P = 0.08) and FM (P = 0.02), whereas G:F was similar (P = 0.68) between TRANS and FM. Mean plasma cortisol concentrations tended (P <= 0.09) to be greater in TRANS vs. FM and CON but was similar (P = 0.87) between CON and FM. Plasma NEFA concentrations were greater (P <= 0.02) for TRANS and FM vs. CON on d 1 and greater (P <= 0.04) for FM vs. TRANS and CON on d 4. Plasma ceruloplasmin concentrations were greater (P <= 0.03) for TRANS vs. CON on d 1, 4, and 7, greater (P <= 0.05) for TRANS vs. FM on d 4 and 7, and greater (P <= 0.04) for FM vs. CON on d 1 and 4. Plasma haptoglobin concentrations were greater (P < 0.01) for TRANS vs. CON and FM on d 1 and 4 and greater (P <= 0.05) for FM vs. CON on d 1 and 4. In conclusion, flunixin meglumine reduced the cortisol and acute-phase protein responses elicited by road transport but did not improve receiving performance of feeder cattle.
