title: EFFECT OF Fusarium graminearum Schwabe ON PHYSIOLOGICAL QUALITY OF SOYBEAN SEEDS AND WHEAT CARYOPSIS IN ARGENTINA

description: ABSTRACT: F. graminearum is the main causal agent of Head blight in cereals in Argentina. This is a disease that develops during the host floral state. When the reproductive structures in the host are invaded, grains may be shriveled and reduced in weight, causing a decrease in yield. Physiological diagnostic techniques on seeds detect the damages produced by this fungus could be used to take decisions related to the quality of seed lots. The objective of this study was to evaluate the possible physiological damage caused by F. graminearum isolates in soybean seeds and wheat caryopsis. Seeds and caryopsis were obtained from plants exposed to fungal infection and were evaluated under two situations: artificial inoculations under greenhouse conditions and natural infection from fields of Santa Fe Province (33°43'22''S; 62°14'46''W). Seed weight, topographical tetrazolium test, standard germination test, electrical conductivity test and X-ray test were performed in soybean seeds and wheat caryopsis from each treatment. Differential behaviors of F. graminearum strains in susceptible soybean and wheat cultivars under greenhouse conditions revealed specific interactions among soybean and wheat genotypes with this fungus. F. graminearum infection in susceptible cultivars under greenhouse conditions produced a significant decrease in the physiological quality of soybean seed and wheat caryopsis. These behaviors were not detected under field conditions in the evaluated locations. All seed quality tests used in this experiment were useful to show differences in infection in soybean and wheat independently of F. graminearum infection.

title: AGRONOMIC EFFICIENCY OF THE INTERCROPPING LETTUCE-ARUGULA FERTILIZED WITH ROOSTERTREE

description: Abstract: The present work aimed to evaluate the agronomic performance of lettuce-arugula intercropping fertilized with different amounts of roostertree biomass incorporated into the ground. The experiment was conducted during the period of September to November of 2011, in the research area of the Experimental Farm Rafael Fernandes, Universidade Federal Rural do Semi-Árido, Mossoró-RN. The experimental design used was randomized blocks with five treatments and four replications. The treatments consisted of the following biomass amounts of roostertree incorporated into the soil (5, 15, 25, 35, and 45 t ha- 1 on a dry basis). The characteristics evaluated in the vegetables were: height and diameter of plants (lettuce), number of leaves per plant, productivity (lettuce), yield of green mass (arugula) and dry mass of shoots. The efficiency of intercropping system was determined through the score of the canonical variable. The optimization of the agronomic performance of the lettuce intercropped with arugula was made possible with the incorporation of about 37 t ha-1 of roostertree into the ground. The use of roostertree as green manure is agronomically viable in the intercropping of lettuce and arugula besides contributing to a better use of environmental resources.

title: INHERITANCE OF RESISTANCE TO Papaya ringspotvirus IN WATERMELON

description: ABSTRACT: Aiming to study the genetic control of Papaya ringspot virus, type watermelon (PRSV-W) in watermelon, the cultivar Crimson Sweet (P1 - susceptible) and L26 derived from PI 244019 (P2 - resistant), as well as the resulting populations F1, F2, RC11 and RC21 of the cross of both lines were evaluated. The trials were carried out in a greenhouse, and the evaluations were done using artificial inoculations with PRSV-W isolates. The seedling symptoms were recorded using a graded scale, and the serological evaluation was done with specific antiserum using indirect ELISA. The estimated variances of the populations were used to obtain the genetic (σ2G)the environmental (σ2E), phenotypic (σ2F2), additive (σ2A) and dominance (σ2D) variances as well as the broad (h2a) and narrow sense (h2r) heritabilities. The hypothesis of monogenic inheritance was tested under different presumed average degrees of dominance as well as using the maximum likelihood. The distribution of resistant plants in the segregating populations was different from a distribution based on monogenic inheritance for all presumed average degrees of dominance, therefore, the hypothesis of monogenic inheritance was rejected indicating that this character in the line L26 is controlled by more than one major gene with the presence of modifiers. The additive-dominant model was adequate to explain the type of gene action involved, and the epistatic effects were not important in the expression of the resistance. The estimated average degree of dominance indicated complete dominance. The broad sense heritabilities for the two variables analyzed were intermediate.

title: SPATIAL DISTRIBUTION OF PHYSIOLOGICAL QUALITY OF SOYBEAN SEED PRODUCTION FIELD

description: ABSTRACT: The objective of this study was to identify and determine the spatial distribution of the physiological quality of soybean seeds in a field of 39 hectares with production through precision farming techniques. Soil sampling and harvest seeds, georeferenced points for determining soil fertility, seed quality and range of spatial dependence were performed. The results were submitted to analysis of descriptive statistics, Pearson correlation, and geostatistics. The data presented coefficient of variation of 1,63% for emergency, 1,74% for germination, 1,63% for viability, 2,59% for accelerated aging and 4,28% vigor evaluated by the tetrazolium test. Soil pH was negatively correlated with germination, emergence, and viability. The grid point per hectare and a georeferenced grid sampling, spacing of 100 meters between points, was efficient in assessing the spatial variability. Physiological quality is not uniform, particularly in nexion of vigor, providing better diagnosis through interpolation maps. Precision agriculture allows one to determine the spatial distribution of seed physiological quality in a production area of soybean seeds, facilitating decision-making, in what refers to the areas to be harvested.

title: GERMINATION AND MORPHOLOGICAL OF SEED AND SEEDLING OF Albizia edwallii (Hoehne) Barneby & J. W. Grimes

description: ABSTRACT: This study aimed to characterize the morphology of seeds and seedlings and evaluate the germination of seeds of Albizia edwallii submitted to different substrates and temperatures. In physical characterization were evaluated thousand seed weight, the number of seeds per kilogram and moisture content. To determine the morphological characteristics, it was evaluated the biometry of 50 seeds, as well as its internal and external characteristics. Germination was conducted at three temperatures (20 ° C, 25 ° C and 30 ° C) and three substrates (sand, vermiculite and blotting paper) with five replications of 40 seeds per treatment, in a factorial 3 x 3 and completely randomized design. The variables were germination percentage, germination rate index, mean germination time, and synchronization index. The thousand seed weight was 47.7 g, while the number of seeds per kilo was 20.964 for the moisture content of 13.1%. The seeds have an elliptical shape, no endosperm and have persistent funiculus. Germination is epigeal, and the seedling is phanerocotylar being fully formed at 15 days. Temperatures of 20 ° C and 25 ° C provide the highest germination rates, 42 and 38%, respectively, and germination speed index (GSI). The use of sand as a substrate provided better germination percentage than the other substrates. Thus, it is recommended to use sand as a substrate and temperatures of 20 ° C and 25 ° C in A. edwalli germination tests.

title: MODELING OF THE DRYING PROCESS THE SEEDS OF COWPEA

description: ABSTRACT: The study aimed to model the drying curves of cowpea beans (Vigna unguiculata (L.) Walp.) in different temperatures determine the coefficient of effective diffusion and the activation energy. For this, we used seeds of beans-cowpea cultivar BRS Guariba, harvested manually, with a water content of 21% (wet basis), dried until the water content 11% (wet basis). Drying was performed in the experimental dryer under controlled temperatures of 30, 40 and 50 °C ± 1 °C, and relative humidity of the air drying between 14 and 59%. 12 models of non-linear regression were tested and for selection the best model was considered to: the significance of the regression coefficient t test, the magnitude of the adjusted coefficient of determination (R²), the average relative error (P) and the estimated average error (SE). It was observed that the drying time for of the beans-cowpea seeds was 10,4 ; 5,6 ; and 2,1 h to the temperatures of 30, 40 and 50 °C, respectively; among the number tested, the mathematical model the Midilli was the best fit to experimental data. The coefficient of diffusion increases with temperature, with values between 5,047 x 10-11 to 12,011 x 10-11 m² s-1 for the temperature range from 30 to 50 °C. The relationship between the coefficient of diffusion effective and the drying temperature can be described by Arrhenius equation, which presents activation energy of 35,04 kJ mol-1 for spreading the liquid in the drying process of the of beans-cowpea seeds.
