Thus, this research was carried out with the aim of evaluate the foliar nutrient contents in response to nitrogen and potassium fertilization, that provide high yield in blackberry cultivars in the edaphoclimatic conditions of the Alto Vale do Jequitinhonha. Three different experiments were performed: In the first one, the production of blackberry cultivars in the 3rd productive cycle was evaluated, following the management of the proposed fertilization for the Brazilian conditions; in the second, doses of N, 30; 45; 60 and 75 g per plant were evaluated and in the third, doses of K2O, 10; 20; 30 and 40 g per plant were evaluated. 'Brazos', 'Guarani', 'Tupy' and 'Xavante' were blackberry cultivars evaluated in the three experiments. The work was carried out in Diamantina, MG, located at 1,384 m altitude. The region?s climate is type Cwb, with average annual temperature of 18.3 ?C, average annual rainfall of 1,468 mm and soil classified as Quartzarenic Neosol. The characteristics evaluated in the experiments were the production and foliar nutrient concentrations of blackberry cultivars and soil chemical attributes. Nitrogen and potassium fertilization recommended for cultivation under Brazilian conditions is not sufficient to maintain nutrient contents at levels adequate for the growth and production of blackberry cultivars in the edaphoclimatic conditions of the Alto Vale do Jequitinhonha. Fertilization increase to 75 g of N per plant and 40 g of K2O per plant made it possible the adaptation of the N and K foliar contents, respectively. The cultivars blackberry present distinct demand for nutrients. 'Brazos' is the cultivar with greater nutritional requirement and greater production. Nitrogen was the nutrient observed with highest content in dry matter of blackberry cultivars.

Master of Science / Horticulture, Forestry, and Recreation Resources / Candice A. Shoemaker / Low fruit and vegetable (FV) intake and low physical activity (PA) levels are linked to increased risk of chronic diseases such as overweight and obesity, diabetes mellitus, and cardiovascular diseases. American Indians/Alaska Natives (NA) seem to be even more susceptible to these chronic diseases when compared to the general United States (U.S.) population, though little research has been conducted on smaller NA tribes. Gardening has been shown to increase vegetable consumption and be a means of PA. The purpose of this study was to see if gardeners of the Prairie Band Potawatomi Tribe (PBPN) in Kansas were more likely to have positive health indicators than non-gardeners. The objective was to discover if PBPN gardeners were more likely than non-gardeners to eat the daily recommended amount of fruit (2 servings) (Center for Nutrition Policy and Promotion, 2015a), eat the daily recommended amount of vegetables (3 servings) (Center for Nutrition Policy and Promotion, 2015b), meet the weekly recommended amount of PA (Centers for Disease Control and Prevention, 2009), perceive their health to be good, and determine if PBPN gardeners meet the weekly recommended amount of PA through gardening activities. Surveys were utilized to gather gardening and health information for PBPN tribal members. Data was coded and descriptive and contingent statistical analyses were performed. Gardeners were more likely than non-gardeners to eat the daily recommended amount of vegetables, the daily amount of both FV, and meet all FV and PA recommendations. Most gardeners met PA recommendations through gardening activities. Gardeners were not more likely than non-gardeners to eat the daily recommended amount of fruit, meet the recommended amount of PA, or to perceive their health as good. Encouraging gardening seems promising as a means of encouraging healthy lifestyles.

Apesar dessa alta produtividade, a fenologia é altamente sazonal, ocorrendo períodos de escassez de recursos e alta produtividade no mesmo ano e/ou entre anos. Os frugívoros exibem uma ampla variedade de adaptações comportamentais e ecológicas para superar esses períodos de escassez. O presente trabalho avaliou as variações temporais na disponibilidade de frutos consumidos por vertebrados frugívoros na Ilha Anchieta, São Paulo, Brasil. Nós procuramos responder às seguintes questões: Os padrões de frutificação e disponibilidade de frutos diferem entre arbóreas e palmeiras? e Os padrões fenológicos de frutificação diferem entre grupos de palmeiras com diferentes síndromes de dispersão?. Os padrões fenológicos foram sazonais para ambos os grupos, no entanto, as datas de ocorrência dos eventos de frutificação foram diferentes. A produção de frutos também foi diferente entre palmeiras e arbóreas, sendo que as palmeiras constituíram mais de 80 por cento do total da biomassa coletada. Os padrões fenológicos foram diferentes entre as palmeiras com diferentes sub-síndromes de dispersão (dispersas por roedores, mistas e aves) fornecendo recursos alimentares para diferentes grupos de frugívoros ao longo do ano. As palmeiras poderiam constituir um recurso alimentar alternativo em períodos de baixa disponibilidade de frutos embora não forneçam recursos para os diferentes tipos de frugívoros da Ilha Anchieta o ano todo. / Tropical rainforest is considered one of the world s most productive habitats where fruit biomass ranges between 180-1000 kg/ha/yr. Despite this broad fruit production, phenology is highly seasonal in tropical forests, showing alternate periods of fruit scarcity and high resource production both in the same year and/or between different years. Frugivores exhibit a variety of ecological and behavioral adaptations to overcome these fluctuations. We evaluate the temporal variation in the availability of fruits consumed by vertebrate frugivores on Anchieta Island, in the Brazilian Atlantic Forest, Northeast São Paulo State. We aim to answer the following questions: Do fruiting patterns and the availability of fruits consumed by vertebrate frugivores differ between palms and trees? Do palm fruiting patterns differ among seed dispersed groups (rodent, mixed and bird)? Phenological patterns were seasonal for both trees and palms; however, the times of occurrence of fruiting differed. Fruit fall biomass was also different between trees and palms, and palms constituted more than 80 percent of the overall fruit fall biomass. Phenological patterns differed between the seed dispersed palms groups (rodent, mixed and bird seed dispersed palms) providing food resources in distinct periods for different assemblages of vertebrate frugivores. Palms may constitute an alternative food resource in periods of low fruit availability, although they do not provide resources for the entire assemblage of vertebrate frugivores on Anchieta Island all year.

Uma das características importantes do suco é a cor, constituindo uns dos índices de qualidade no mercado de sucos, podendo ocorrer alteração da cor durante o processamento e armazenamento, o que pode implicar em não aceitação por parte do consumidor final. Isso pode ocorrer principalmente devido a reações bioquímicas de escurecimento e a alterações bioquímicas moleculares que resultam em flavors indesejáveis, perda de nutrientes, e formação de pigmentos de coloração marrom. Então o controle do escurecimento durante o armazenamento e processamento de frutos é muito importante para a preservação da aparência natural dos mesmos. Deste modo as enzimas polifenoloxidase (EC: 1.10.3.1; PPO) e a ascorbato oxidase (EC: 1.10.3.3; AO) podem ser responsáveis pelo escurecimento enzimático que fornece alteração de cor. O objetivo desse trabalho é estudar a PPO, a AO e sua influência no processo de escurecimento da fruta maracujá. Os resultados principais desse estudo foi que o pH ótimo de ensaio da PPO foi de 6,0 e da AO de 5,0, e suas temperaturas ótimas de 50°C (PPO) e 45°C (AO).

An important feature is the color of the juice, making each of the indices of quality in the juice market, change in color may occur during processing and storage, which may not imply acceptance by the consumer. This can occur mainly due to biochemical reactions dimming molecular and biochemical changes that result in undesirable flavors, loss of nutrients, and formation of brown pigments. Then the control browning during storage and processing of fruits is very important to preserve the natural look of them. Thus the enzyme polyphenol oxidase (EC: 1.10.3.1, PPO) and ascorbate oxidase (EC: 1.10.3.3; AO) may be responsible for enzymatic browning that provides color change. The objective of this paper is to study the PPO , AO and its influence in the process of darkening of the passion fruit.
