Flutuação populacional de Meloidogyne enterolobii em pomar de goiabeira (Psidium guajava)

The objective of this work was to study the population fluctuation of Meloidogyne enterolobii in a commercial orchard of 'Paluma' guava with five years of age, under micro sprinkler irrigation system and usual practices for this crop. In the orchard, located in the municipality of Vista Alegre do Alto (SP) Brazil and infested by M. enterolobii, five plants exhibiting nematode symptoms were selected for monthly sampling from July 2007 to June 2008. Two single samples of rhizosphere soil and guava roots were collected from each plant, with the aid of hoe to a depth of 20 cm on the projection of the trees, forming a composite sample per plant. In nematology laboratory of Faculdade de Ciencias Agrarias e Veterinarias Universidade Estadual Paulista, eggs and second stage juveniles (J2) of M. enterolobii were extracted from the samples and quantified. There was not a marked seasonal variation in the nematode population in soil or roots, possibly as a result of the guava vegetation stimulated by irrigation or the presence of invasive plants during the experimental period. However, the soil density reached a peak in January, corresponding to the month of elevated rainfall and temperatures. In roots, there were two significant peaks, in February and a major peak in August. There was a negative correlation between nematode populations in soil and roots.

Efeitos de diferentes tipos de poda nos teores de nutrients emflores e frutos de goiabeira

A better understanding of the differences between the levels of nutrients, depending on the type of pruning used in the cultivation of the guava tree, may allow a more adequate understanding of the physiological processes of this fruit. The analysis of flowers is a tool that can be used to assist in assessing the nutritional status of crops, especially perennials. We evaluated the effects of different types of pruning on nutrient concentrations in flowers and fruit, at different developmental stages and in different parts of the fruit. The study was carried out in Vista Alegre do Alto, in orchards of guava variety Paluma. Flowers and fruit were collected in orchards, one under heavy pruning and the other with continuous pruning. The fruit were collected in two stages (two millimeters length and mature) and divided into basal part and apex, with the top toward the stalk. Flowers were collected in the same orchards as the fruits, sampling the basal part and apex of the flowers. F tests were performed and, when necessary, the Scott-Knott test at α= 5%. Overall, there were nutritional differences among flowers and fruits in relation to the type of pruning employed; drastic pruning provided higher levels of nutrients compared with continuous pruning. In relation to the portion of the samples, especially for fruit, there were differences between the apex and base, as well as between different stages of fruit collection.

Mume clonal rootstocks for 'Aurora-1' peach in São Paulo State, Brazil

In spite of significant results achieved with scion genetic improvement in stone fruits, the peach culture in Brazil still needs studies and new technologies regarding the use of rootstocks. A wide research project has being developed at the Faculdade de Ciências Agrárias e Veterinárias (FCAV/UNESP), Jaboticabal, Brazil, dealing with the use of mume clones (Prunus mume) as rootstocks for peach trees, which has produced promising results. In this research, two mume genotypes propagated by herbaceous cuttings were tested as rootstocks for peach cultivar Aurora-1. Three different tree spacing were used: 6 x 2 m, 6 x 3 m and 6 x 4 m. The experiment was carried out at Vista Alegre do Alto (21°10'14 S, 48°37'45 W, 700 m of altitude), São Paulo State, Brazil. Growing field conditions included Hapludalfs soil with medium sandy texture and using micro sprinkler irrigation. The region has an average chilling accumulation 17.9 hours per year. The evaluations were taken in 2005 and 2006 (2nd and 3rd year after planting, respectively). The trunk diameter was evaluated every three months, from the 24th to the 41st month after planting, totalizing seven evaluations. Plants on 'Rigitano' had higher trunk diameter on the 33rd, 39th and 41st month after planting (May/06, November/06 and February/07, respectively). No significant differences were observed in the other evaluations. The diameter at 5 cm above to the graft point was larger than below, but no incompatibility symptoms were observed between rootstocks and scion. Spacing tested did not influence trunk diameter, phenology and flower bud production in 'Aurora-1' scion. In conclusion, 'Rigitano' and 'Clone 15' are recommended for high density plantings of peach 'Aurora-1' in Brazil, and the 6 x 2 m spacing can be recommended, with productivity advantages for peach under low air relative humidity and mild winter conditions. © ISHS 2012.

Adubação nitrogenada e potássica em goiabeiras ‘paluma’: II. efeito no estado nutricional das plantas

The proper mineral fertilization of guava orchards under intensive management, is a major factor in productivity and monitoring the nutritional status of the plants contributes to the efficiency of this agronomic practice. The aim of this study was to investigate different doses of nitrogen and potassium in the nutritional status of guava 'Paluma'. The experiment was conducted at Vista Alegre do Alto, Sao Paulo, in a 7 year old irrigated orchard, managed with fruiting pruning during four consecutive growing seasons. The soil is a dystrophic Ultisol. The experimental design was randomized blocks, in factorial, with four nitrogen doses (0, 0.5, 1 and 2 kg of N plant(-1)) and four of potassium (0, 0.55, 1.1 and 2.2 kg of K2O plant(-1)), with three replications. Nitrogen fertilization promoted increased levels of leaf N and Mn and the decrease in the levels of P and B; effects observed from the second to the fourth production cycle. Nitrogen fertilization increased the Ca and Mg levels, respectively, in the second and third cycle. Except for the first production cycle, K and Mn foliar concentrations increased with increasing potassium fertilization, whereas the levels of Mg, in the second and the fourth cycle, decreased as a function of fertilization.

Adubação nitrogenada e potássica em goiabeiras ‘paluma’: I. efeito na produtividade e na qualidade dos frutos para industrialização

The nutrition of the orchards is the major factor of productivity, being necessary to know the proper doses of fertilizers and their influence on fruit quality attributes for industrialization. This study evaluated the effects of different doses of nitrogen and potassium on the productivity of guava trees and also on the values of pH, soluble solids (SS), titratable acidity (TA) and pulp/kernel ratio of guavas. The experiment was conducted at Vista Alegre do Alto, SP in an irrigated 'Paluma'guava orchard, 7 years old, managed with pruning during three consecutive cycles of production. The soil of the area was dystrophic Ultisol. The experimental design was the randomized blocks, in factorial, with four nitrogen doses (0, 0.5, 1 and 2 kg of N plant(-1)) and four of potassium (0, 0.55, 1.1 and 2.2 kg of K2O plant(-1)), with three replications. Nitrogen fertilization increased productivity and the pH of the fruit, being explained by the quadratic polynomial regression models; reduced linearly the pulp/kernel ratio and do not influenced the SS and TA values. On the other hand, potassium fertilization and N x K interaction had no significant effects on productivity and the other characteristics evaluated.

Irradiação e atmosfera modificada passiva na qualidade pós-colheita de goiabas 'Pedro Sato'

The aim of this study was to evaluate the effect of gamma radiation associated with modified atmosphere on postharvest quality of guavas ‘Pedro Sato’. It was used guavas from the region of Vista Alegre do Alto/São Paulo/Brazil. After harvest, the fruits were immediately transported to the Fruit and Vegetables Laboratory from the Agroindustrial Management and Technology Department, Agronomic Sciences College - UNESP - Botucatu / SP, where they were kept at 10 ° C and 90-95% RH in cold storage, for 28 days. It was used the randomized design, with factorial scheme 5 x 5, three repetitions. The first factor consisted of the following effects: control 1 (without package or irradiation), control 2 (polystyrene package/PS + package low density polyethylene/LDPE and without irradiation), treatment 1 (PS + LDPE and 0.2 kGy ), treatment 2 (PS + LDPE and 0.6 kGy) and treatment 3 (PS + LDPE and 1.0 kGy). The second factor consisted of the evaluation periods: 0, 7, 14, 21 and 28 days. The analyses were: firmness, soluble solids (SS), titratable acidity (TA), maturity index, pH, respiration rate. Concluded that high doses of irradiation promoted a negative effect on physical-chemical characteristics of guava ‘Pedro Sato’, verifying that only the lowest dose associated with modified atmosphere provided fruits with higher quality and acceptability, due to higher maturation rate and soluble solids obtained. Regarding the days of analysis, there were no positive effect of the treatments during storage, where only the early days promoted better values for the variables studied.

Conservação de goiabas ‘Pedro Sato’ minimamente processadas e irradiadas

The aim of this study was to evaluate the effect of gamma irradiation associated with modified atmosphere in cold storage of guava ‘Pedro Sato’ minimally processed, checking their physical-chemical characteristics. Were used guavas from the region of Vista Alegre do Alto/São Paulo/Brazil. After harvest, fruits were immediately transported to the Fruit and Vegetables Laboratory from the Agroindustrial Management and Technology Department, Agronomic Sciences College - UNESP - Botucatu / SP, where they were kept at 10 ° C and 90-95% RH in cold storage, for 12 days. In the laboratory, fruits were selected by size and lack of defects in order to standardize the lot and then were cut into slices 0.5 cm thick. We used the completely randomized design, with factorial design 5 x 5, with three replications. The first factor consisted of the following effects: control 1 (without package or irradiation), control 2 (polystyrene package/PS + package low density polyethylene/LDPE and without irradiation), treatment 1 (PS + LDPE and 0.2 kGy ), treatment 2 (PS + LDPE and 0.6 kGy) and treatment 3 (PS + LDPE and 1.0 kGy). The second factor consisted of the evaluation periods: 0, 3, 6, 9 and 12 days. The analyses were: firmness, soluble solids (SS), titratable acidity (TA), maturity index, pH, breathing behavior. In the end of this work it was concluded that the lower dose of radiation associated with modified atmosphere promoted positive effect on physical-chemical characteristics of guava ‘Pedro Sato’, providing fruits with higher quality and durability, due to higher maintenance of pulp firmness, the highest pH and soluble solids obtained. Regarding the storage days, there were no beneficial effect of the treatments during storage, mainly due to the sensitivity of fruits submitted to gamma irradiation, where only the early days provided better values for the variables.

Prática de ensino supervisionada em educação pré-escolar e ensino do 1º ciclo do ensino básico: tornando-se educadora/professora

O presente relatório da Prática de Ensino Supervisionada (PES) resulta da observação e participação no contexto da PES em Educação Pré-Escolar realizado em Florianópolis, Santa Catarina (Brasil), através do programa Luso-Brasileiro, no Núcleo de Educação Infantil Colónia Z-11 e da PES em 1º Ciclo do Ensino Básico na Escola EB1 da Quinta da Vista Alegre, pertencente ao Agrupamento Manuel Ferreira Patrício de Évora. O relatório centra-se no meu percurso e aprendizagens como futura educadora/professora: ir aprendendo a profissão em contexto, indo ao encontro de quem somos e em quem nos vamos tornando, dando enfase ao papel das crianças nos processos de aprendizagem que experimentámos. Na conceção da ação educativa, tornada prática pedagógica em contexto, a avaliação, formativa e transformadora, assim como a reflexão acerca da prática foram fundamentais para o melhoramento da intervenção e, por tal, influências positivas na aprendizagem das crianças e na minha aprendizagem profissional. A problemática deste relatório teve como base o querer compreender relações entre uma reflexão sistemática, por escrito, sobre o desenvolvimento do meu projeto de formação em contexto, considerando que a avaliação formativa deveria nortear e monitorizar o nosso trabalho, as relações e aprendizagens, na ação docente que ia desenvolvendo, quer em Educação Pré-Escolar quer no 1º Ciclo. Neste percurso, entrelaçando a ação e a investigação, procurei respostas para as seguintes questões: o que sabia acerca da docência que se pauta por uma avaliação formativa e formadora no trabalho com crianças? O que fiz para aprendermos em conjunto, tendo em conta uma função reguladora que a avaliação poderia tomar? Como o fiz? Em que momentos e com quem? Para quê, com que finalidade? O que aprendi no decorrer deste processo de aprendizagem profissional, onde a investigação-ação teve um papel relevante?; Supervised Teaching Practice’s Report to obtain a Master’s Degree in Preschool and Primary school: Abstract: The present report of Supervised Teaching Practice (STP) is a result of the observation and participation in context of STP in pre-school that took place in Florianópolis, Santa Catarina (Brazil), through the Luso-Brazilian program, in Núcleo de Educação Infantil Colónia Z-11 and through STP in Primary School of Ensino Básico in Escola EB1 da Quinta da Vista Alegre, which belongs to the Manuel Ferreira de Évora Group. The report focuses on my journey and learnings as a future teacher: learning the profession in it’s actual context, trying to find who we are and what we can become, and emphasizing the children’s role in these learning processes. In the conception of the education activities, which became possible by pedagogical practice in context, the evaluation, formative and transformative, as well as the reflection about the practice were vital to improve the intervention and, consequently, to have a positive influence in the children’s learning process and in my own professional experience. The main focus of this report is to understand the relation between a systematic reflection, in writing, about the development of my teaching in context project, considering that the formative evaluation should guide and monitor our work, the relationships and learnings, in the educational process that I developed, either in pre-school or primary school. In this journey, by combining action and investigation, the main intention was to answer the following questions: What did I know about teaching characterized by a formative assessment when working with children? What did I do so we could learn together, bearing in mind a regulative function that evaluation could take? How did I do it? In what moments and whom with? What for, and what was the purpose? What did I learn throughout this professional learning process, where the investigation-action played a major role?
