title: Arbuscular mycorrhizal fungi in soil aggregates from fields of "murundus" converted to agriculture

description: The objective of this work was to evaluate the spore density and diversity of arbuscular mycorrhizal fungi (AMF) in soil aggregates from fields of "murundus" (large mounds of soil) in areas converted and not converted to agriculture. The experiment was conducted in a completely randomized design with five replicates, in a 5x3 factorial arrangement: five areas and three aggregate classes (macro-, meso-, and microaggregates). The evaluated variables were: spore density and diversity of AMF, total glomalin, total organic carbon (TOC), total extraradical mycelium (TEM), and geometric mean diameter (GMD) of soil aggregates. A total of 21 AMF species was identified. Spore density varied from 29 to 606 spores per 50 mL of soil and was higher in microaggregates and in the area with 6 years of conversion to agriculture. Total glomalin was higher between murundus in all studied aggregate classes. The area with 6 years showed lower concentration of TOC in macroaggregates (8.6 g kg-1) and in microaggregates (10.1 g kg-1). TEM was greater at the top of the murundus in all aggregate classes. GMD increased with the conversion time to agriculture. The density and diversity of arbuscular mycorrhizal spores change with the conversion of fields of murundus into agriculture.

title: Mapping adsorbed phosphorus through soil color and magnetic susceptibility

description: The objective of this work was to evaluate the possibility of mapping adsorbed phosphorus through soil color and magnetic susceptibility. The experiment was done in a 380-ha sugarcane area, which included four types of Oxisols, with different texture and natural fertility. Two hundred and forty-one soil samples were collected at 0.00-0.25-m depth. The soil redness index was calculated from sample values of hue, value, and chroma, obtained with diffuse reflectance spectroscopy. Regression models were adjusted between adsorbed phosphorus and soil magnetic susceptibility or redness index. Data spatial dependence was evaluated with geostatistics. Magnetic susceptibility is significantly correlated to adsorbed phosphorus, which allows it to be used as a component in pedotransfer functions for indirect quantification of soil adsorbed phosphorus. The redness index and the magnetic susceptibility show spatial dependency with adsorbed phosphorus. Soil magnetic susceptibility and redness index, evaluated with diffuse reflectance spectroscopy, can aid in the mapping and identification of areas with different phosphorus adsorption potential.

title: Genotype x environment interaction for weight at 365 days in Mediterranean buffaloes

description: Abstract: The objective of this work was to verify the presence of the genotypes x environments interaction (GxE) for weight at 365 days of age in the Mediterranean breed of buffaloes, using models of reaction norms through random regression. The standard animal model and the models of reaction norms were tested, and the hierarchical model reaction norm (MRN) was evaluated with one and two steps. The homoscedastic hierarchical model of reaction norms with one-step (HMRNHO1s) had the best fit, based on three criteria for comparison. The direct heritability estimates for this model ranged from 0.19 to 0.78, with environment improvement. Besides, direct breeding values (scale effect) changed for some breeders, which indicates the existence of GxE interaction. The Spearman correlations were high, both in the comparison between the standard animal model and MRN, as in the comparison between low, medium, and high management levels in HMRNHO1s. Therefore, although there is GxE interaction, the ranking of breeding animals is not significantly affected by the models. The majority of buffaloes is formed by animals with robust genotypes, which are less sensitive to environmental changes.

title: Optimal fractions of phosphorus fertilizer applied in preplanting and in drip fertigation of tomato crop

description: Abstract:The objective of this work was to establish the optimal fractions of the total amount of phosphorus to be applied in preplanting and in drip fertigation of determinate-growth tomato, as well as to determine the effect of the different forms of nutrient application on their soil spatial distribution. Treatments consisted of five schemes of fertilizer application: 100, 75, 50, 25, and 0% of P total dose divided between the pre-planting (triple superphosphate in band placement) and the fertigation (phosphoric acid). The experiment was carried out in a clayed Oxisol with two P availability classes - 7.5 and 32.9 mg dm-3 (Mehlich-1). The treatments showed no effect on tomato production variables in the soil with high P availability. However, in the soil with smaller availability of the nutrient, P fertigation showed a quadratic effect on fruit yield, net income, and net rate of return. The best results were obtained with half of the P total dose applied by fertigation. The fertigation allowed P movement in the soil up to 30 cm deep, and horizontal movement up to 15 cm.

title: Microbial biomass carbon in Oxisol determined by wet oxidation and combustion at high temperature

description: Abstract: The objective of this work was to evaluate the relationships between the methods of wet oxidation and the combustion at high temperature, used in determinations of microbial biomass carbon, and to verify the necessity of using correction factors between the two methods. Ninety-six soil samples, collected at 0-10-cm soil depth in clayey Oxisol of the Cerrado region, under annual crops, pastures, eucalyptus, and native vegetation were used. The microbial biomass carbon was determined from K2SO4 extracts, using the fumigation-extraction method, by wet oxidation with potassium dichromate and external heating, and by combustion at high temperature in a total organic C analyser. A significant, positive, linear relationship between the contents of organic C, determined by the two methods, was observed. The combustion at high temperature method detects, on average, 6.3% more organic C than the wet oxidation method.

title: Physical and chemical composition of the must and white wine of grapevine cultivars in response to rootstocks

description: Abstract: The objective of this work was to evaluate the influence of the rootstocks 'IAC 766 Campinas' and '106-8 Mgt Ripária do Traviú' on the physicochemical characteristics of must and wine of the 'IAC 116-31 Rainha', 'IAC 21-14 Madalena', and 'BRS Lorena' grapevines. Grape must was evaluated for pH, soluble solids (SS), total acidity (TA), and SS/TA ratio. In wine, the following physicochemical analyses were performed: density, alcohol content; total, volatile, and fixed acidity; pH; dry extract; reducing sugars; reduced dry extract; alcohol in weight/reduced dry extract; free and total sulfur dioxide; total polyphenol index (I 280); total polyphenols; flavonoids; and antioxidant activity. Must characteristics of 'IAC 21-14 Madalena' were not affected by rootstocks; however, the 'IAC 766 Campinas' rootstock promoted higher SS/TA in 'IAC 116-31 Rainha' must and lower SS/TA in 'BRS Lorena' must. The 'IAC 766 Campinas' and '106-8 Mgt Ripária do Traviú' rootstocks influenced pH and alcohol content of 'IAC 116-31 Rainha' wine, the dry extract of 'IAC 21-14 Madalena' wine, and the fixed acidity of 'BRS Lorena' wine. There was no influence of the rootstocks on the phenolic compounds and antioxidant activity of wines.

title: Quality and nutraceutical potential of bovine milk in different production systems and seasons

description: Abstract: The objective of this work was to evaluate the effect of the interaction between production systems and seasons on the chemical and microbiological qualities of bovine milk, besides proposing a potential nutraceutical index of milk fatty acid profiles. Three farms were assessed monthly, along the different seasons, for four specialization levels of the production systems: highly specialized, specialized, partially specialized, and nonspecialized. The production systems and the seasons jointly interfere in fatty acid profiles, and singly interfere in the chemical and microbiological quality of milk. The highest somatic cell counts and the lowest protein contents were observed in the summer, and the specialization level of the production units had an inverse relationship with the total bacterial count. During winter, nonspecialized systems produced milk with the best nutraceutical index, with the highest contents of polyunsaturated fatty acids, rumenic acid (CLA, 18:2n7-c9,t11) and t10,c12-octadecadienoic acid (CLA, 18:2n6-t10,c12).

title: Fruit quality preservation of 'Fuyu' persimmon by preharvest and postharvest treatments with 1-methylcyclopropene

description: Abstract: The objective of this work was to compare the effects of preharvest spraying of aqueous 1-methylcyclopropene (1-MCPa) and of postharvest treatment of gaseous 1-methylcyclopropene (1-MCPg) on fruit maturity and quality of 'Fuyu' persimmon (Diospyros kaki) . Spraying of 150 mg L-1 1-MCPa was done on trees in the first week of commercial harvesting. Fruit were harvested at 1, 7, 14, and 21 days after 1-MCPa spraying (DAMS), and treated or not with 0.6 μL L-1 1-MCPg one day after harvest. The treatments consisted of a control, 1-MCPa, 1-MCPg, and 1-MCPa+1-MCPg. Fruit were stored at 0°C for 70 days in modified atmosphere, followed by seven days at 23°C. The treatment with 1-MCPa did not affect fruit maturity on trees, but reduced the premature flesh softening and the occurrence of translucent stain disorder at postharvest. The incidences of soft fruit after storage (average of three years) were higher than 84% for the control, and lower than 18% for fruit treated with 1-MCPg, regardless of fruit harvesting date, and they were 15, 34, 40, and 75% for fruit treated with 1-MCPa and harvested at 1, 7, 14, and 21 DAMS, respectively. The efficacy of 1-MCPa is equivalent to that of 1-MCPg for fruit harvested at 1 DAMS and its is reduced by delaying fruit harvest from the date of its application.
