title: Economic viability of ‘Niágara Rosada’ grape production in the north and northwest regions of Rio de Janeiro

description: Abstract The ‘Niágara Rosada’ grape (Vitis labrusca) is the main table cultivar produced in the North and Northwest Regions of the Rio de Janeiro State. This cultivar presents greater rusticity and lower production cost than the cultivars of fine grape (Vitis vinifera L.) because it is more resistant to diseases and the absence of some cultural treatments. The research aimed to determine the economic affordability of the production of ‘Niágara Rosada’ grapes in the north and northwest regions of Rio de Janeiro state, by calculating the Net Present Value (NPV) and the Internal Rate of Return (IRR), and to identify the risk of viticulture, through the sensitivity analysis and the use of the Monte Carlo method. To collect the data, questionnaires, and interviews were applied directly to the wine producers on the technical coefficients and respective production costs of the grape in 1 ha. The results highlighted that viticulture could be a good alternative for the regions, with satisfactory profitability. The variables with the most significant effect on profitability were the sale price of the product, the cost of labor, and the price of packaging. The probability of winegrowers to obtain a negative NPV is 33.32%, considering an attractiveness rate of 6% per year.

title: Culture media and bap concentrations in the embryo culture of ‘BRS Kampai’ peach

description: Abstract Early-ripening peach cultivars present difficulties in the process of natural germination of seeds. In order to solve this problem, the culture of embryos in vitro can be considered an alternative, in which seeds find conditions to complete germination and development in a satisfactory way. Different protocols and culture media have been tested to meet the nutritional needs of the embryo, but they still have problems and need to be optimized. The objective of this work was to test culture media and BAP concentrations in order to increase the germination percentage of embryos and viable ‘BRS Kampai’ peach seedlings, avoiding possible anomalies in the process. The experiment was carried out at the Laboratory of Tissue Culture – “Universidade Tecnológica Federal do Paraná”, Campus of Pato Branco. The experimental design used was randomized blocks, in 2x5 factorial, with four replicates, with plot being represented by 15 embryos. The culture media tested were MS and WPM with five BAP concentrations (0, 1, 2, 3 and 4 mg L-1). In the in vitro period, seed germination was evaluated through the attribution of scores, and embryo development, measuring the length of stem and main root. During the acclimatization period, seedlings were evaluated for survival, stem length, viable seedlings and rosette formation. Considering the conditions under which the experiment was conducted, it was concluded that MS culture medium with the addition of 1 mg L-1 of BAP allowed higher germination percentage and viable ‘BRS Kampai’ peach seedlings.

title: Physiological responses of seeds from full-sib guava families to different substrate temperatures

description: Abstract Guava is an important fruit in Brazil and worldwide. However, research has yet to advance on its breeding and seed technology, an essential factor for the development of productive genotypes with germination potential which would support the continuity of breeding programs. In search of a methodology for routine analysis testing of guava seeds under genetic control, this study examined the effect of temperature and substrate on the germination of guava seeds from full-sib families. The experiment was laid out in a completely randomized design with a 5 × 4 factorial arrangement consisting of the combination of five temperatures (25, 30, 35, 20-30 and 25-35 °C) and four substrates (paper roll, on-paper, in-sand and on-sand), with eight replicates of 50 seeds. Germination, germination speed index and live ungerminated seeds were evaluated. The alternating temperatures of 20-30 and 25-35 °C and the paper roll, on-paper and in-sand substrates are adequate conditions for germination tests with guava seeds.

title: Changes in hormonal balance as key to reserve degradation after dormancy overcoming in Annona macroprophyllata and Annona purpurea seeds

description: Abstract Studies on the effect of the applying of phytoregulators to overcome seed dormancy have been carried out in Annonaceae species, thus the endogenous relationship between abscisic acid and gibberellins after the application of phytoregulators needs to be known in these species. Considering the importance of hormonal balance in dormancy mechanisms, the aim of this research was to elucidate how endogenous ABA and GA concentrations change after the application of phytoregulators in seeds and how these changes affect reserve degradation during germination of Annona macroprophyllata and A. purpurea seeds. Seeds were submitted to three conditions: - no soaking, soaking-in-water and soaking-in-GA4+7+benzyladenine. ABA, GA, lipids, proteins, and total soluble sugars were quantified at 0, 2, 5, 10, and 15 days after the beginning of treatments. The application of phytoregulators led change of the hormonal balance inducing increase in endogenous GA and reduction in ABA levels since seed soaking. During imbibition, the degradation of seed reserves (breaks proteins first, and then soluble sugars and finally lipids) was observed and complete germination was obtained after 10 days, with primary root emission. In both species, dormancy can be broken soon after seed dispersal when the balance between GA and ABA is endogenously changed (by exogenous application of phytoregulators), leading to metabolic reserve degradation and germination.

title: Assessment of economic and environmental performance in citrus-based intercropping systems

description: Abstract The economic and environmental performances of agriculture intercropping depend on the complementarities between the crops that make up the system. The objective of this work was to analyze the citrus-based intercropping systems in the Coastal Tablelands region of Northeastern Brazil, aiming to identify the associations of crops with better economic and environmental performances. The study started with the construction of a set of integrated indicators, with which the field information was recorded and the performance indices calculated, based on three principles: Profitability, Productive Efficiency, and Biological Regulation. Citrus orchards in monoculture resulted in lower environmental economic performance indices. The intercropping systems that yielded the best environmental and economic performance indices in the citrus orchards were: cassava; cassava, corn and beans; corn and pumpkin. The indicators associated with these economic-environmental performances were profit, seasonality, productive diversity, profit evenness, plant health control impact level, and efficiency in the use of water, nitrogen, and phosphate.

title: Passion Fruit (Passiflora spp.) species as sources of resistance to soil phytopathogens Fusarium solani and Fusarium oxysporum f. sp. Passiflorae complex

description: Abstract The stem rot and fusarium vascular wilt are among the main factors the most limiting the passion fruit cultivation in the State of Mato Grosso. This study aimed to evaluate the resistance / susceptibility of the genus Passiflora species to soil pathogens from different biomes of Mato Grosso (Cerrado, Pantanal and Amazon). The part I evaluated the response of P. edulis Sims, P. foetida, P. nitida and P. quadrangularis on eight isolates of F. solani. In part II was evaluated the genotypes P. edulis Sims, P. mucronata, P. foetida, P. nitida and P. morifolia on three isolates of F. oxysporum f. sp. passiflorae. The experimental design was randomized blocks in factorial arrangement (genotypes x isolates). The statistical analysis used for both steps were the variance analyses by F test and grouping of averages of genotypes by Scott-Knott test (P =0.05). Among the isolates of F. solani was found that isolates FS8A and FS3P are more aggressive, indicating genetic variability among isolates. The most resistant genotypes to the pathogen were P. nitidaand P. foetida. Among the isolates of F. oxysporum f. sp. passiflorae there was no significant difference in aggressive levels, and the P. mucronata and P. nitida species are more resistant to Fusarium. Thus genotypes P. nitida, foetida and P. mucronatacan be indicated as a resistance source to improvement of commercial passionfruit programs.

title: Comparison of fruit maturation and quality of ‘Gala’ apple strains at harvest and after storage

description: Abstract Strains of ‘Gala’ apples with highly red-colored skins have been planted in new orchards based on consumer interest and financial returns to the producers. The effect of somatic mutation may not be limited to change in fruit skin appearance. In this study, six ‘Gala’ strains were compared regarding fruit maturity and quality attributes at commercial harvest time and after 210 days in controlled atmosphere cold storage plus seven days shelf-life. Experimental orchards were established in three regions and fruit assessed over four seasons. The fruit skin red color area was highest in ‘Baigent’ and ‘Galaxy’, and lowest in ‘Royal Gala’ and ‘Imperial Gala’. Fruit of ‘Maxi Gala’ and ‘Gala Real’ had intermediate skin coloration among the six strains. There was no difference among the strains regarding the fruit weight, starch index, flesh firmness, soluble solid content (SSC), and titratable acidity (TA) at harvest, and flesh firmness, SSC and TA after storage. Fruit of the six ‘Gala’ strains were equally affected by physiological disorders (flesh browning, fruit cracking, calcium deficiency disorders and shrivel) and fungal diseases (external decay, core rot and Glomerella cingulata spot) during storage, indicating that they have similar storability. Only ‘Imperial Gala’ and ‘Royal Gala’ exhibited superficial scald, an unusual disorder for ‘Gala’ cultivar. Harvest management and potential economic impacts of highly red colored fruit of ‘Gala’ strains are discussed.

title: Sonographic evaluation of children with congenital hypothyroidism

description: Abstract Objective: To establish benchmarks and study some sonographic characteristics of the thyroid gland in a group of euthyroid children aged up to 5 years as compared with age-matched children with congenital hypothyroidism. Materials and Methods: Thirty-six children (17 female and 19 male) aged between 2 months and 5 years were divided into two groups – 23 euthyroid children and 13 children with congenital hypothyroidism – and were called to undergo ultrasonography. Results: In the group of euthyroid children (n = 23), mean total volume of the thyroid gland was 1.12 mL (minimum, 0.39 mL; maximum, 2.72 mL); a homogeneous gland was found in 17 children (73.91%) and 6 children (26.08%) had a heterogeneous gland. In the group of children with congenital hypothyroidism (n = 13), mean total volume of the thyroid gland was 2.73 mL (minimum, 0.20 mL; maximum, 11.00 mL). As regards thyroid location, 3 patients (23.07%) had ectopic thyroid, and 10 (69.23%) had topic thyroid, and out of the latter, 5 had a homogeneous gland (50%) and 5, a heterogeneous gland (50%). In the group with congenital hypothyroidism, 6 (46.15%) children had etiological diagnosis of dyshormoniogenesis, 3 (23.07%), of ectopic thyroid, and 4 (30.76%), of thyroid hypoplasia. Conclusion: Thyroid ultrasonography is a noninvasive imaging method, widely available, easy to perform and for these reasons could, and should, be performed at any time, including at birth, with no preparation or treatment discontinuation, to aid in the early etiological definition of congenital hypothyroidism.

title: Magnetic resonance imaging and BMB score in the evaluation of bone involvement in Gaucher’s disease patients

description: Abstract Objective: To evaluate by magnetic resonance imaging changes in bone marrow of patients undergoing treatment for type I Gaucher’s disease. Materials and Methods: Descriptive, cross-sectional study of Gaucher’s disease patients submitted to 3 T magnetic resonance imaging of femurs and lumbar spine. The images were blindly reviewed and the findings were classified according to the semiquantitative bone marrow burden (BMB) scoring system. Results: All of the seven evaluated patients (three men and four women) presented signs of bone marrow infiltration. Osteonecrosis of the femoral head was found in three patients, Erlenmeyer flask deformity in five, and no patient had vertebral body collapse. The mean BMB score was 11, ranging from 9 to 14. Conclusion: Magnetic resonance imaging is currently the method of choice for assessing bone involvement in Gaucher’s disease in adults due to its high sensitivity to detect both focal and diffuse bone marrow changes, and the BMB score is a simplified method for semiquantitative analysis, without depending on advanced sequences or sophisticated hardware, allowing for the classification of the disease extent and assisting in the treatment monitoring.
