This paper aims to evaluate the quality of yellow mombin fruit in different maturation stages from clones cultivated in Ceará - CE. For that 'Capuan', 'Lagoa Redonda', 'Genipabu' and 'Gereau' clones was harvested, at different maturation stages, being: 1 (green fruit), 2 (25% to 50% of yellow skin), 3 (75% of yellow skin) and 4 (100% of yellow skin). The fruits were transported to the laboratory of Chemistry of IFCE Campus Limoeiro do Norte - CE, and then were made a selection and the classification of maturity stages by skin color. The experiment was conducted with four treatments (maturation stages) with five replications each consisting of 10 fruits. It was evaluated soluble solids, titratable acidity, pH, vitamin C and Ratio. To the physical parameters, was using only yellow mombin of 3rd stage, and was evaluated weight, length diameter of fruit. The clones presented differences physico-chemical. The 'Gereau' clone had the highest soluble solids. In the stage 4, independent of the clone, was verifying the higher soluble solids content and lower acidity, thus presenting, higher condition of acceptability by consumers and the industry, and the point of harvest more appropriate.

The viruses from the genus Begomovirus, family Geminiviridae are considered emergent pathogens, mainly because of the population explosion of their insect vectors. For this reason, more attention needs to be directed to the correct virus species identification inside the genus. The present paper had the objectives of serologically detecting a begomovirus in Macroptilium lathyroides plants in the State of Ceará, and developing biological, serological and molecular studies with a virus isolate obtained from M. lathyroides. Indirect ELISA with antiserum for Macroptilium golden mosaic virus (MaGMV) demonstrated that the samples collected from M. lathyroides showing golden mosaic in the field were infected with a begomovirus. The virus isolate obtained was transmitted by grafting to eight species of the family Leguminosae, four species of Solonaceae, and one species in the family Amaranthaceae. The virus also was transmitted from M. lathyroides to M. lathyroides by the whitefly Bemisia tabaci biotype B. A DNA fragment of 1.2 kb was obtained by PCR with the primers PAL1v 1978 and PAR1c 496 for component A, and a DNA fragment of 0.5 kb was obtained with the primers PBL1v 2040 and PCR cl for component B, confirming the presence of a begomovirus infecting M. lathyroides. Molecular studies indicated that the begomovirus isolate showed 77% genomic similarity with Bean golden mosaic virus and 75% with Cowpea golden mosaic virus for their cp and rep genes, indicating the possibility that the isolate is a distinct virus species of the Begomovirus genus.

The objective was to evaluate the effect of the biochar as a substrate conditioner for the production of eucalyptus seedlings. The work was lead in nursery and the experimental design was randomized blocks arranged in factorial 5 x 2, being the factors composed of five concentrations of biochar (0; 7.5; 15; 30 and 60% v/v) added to the Germinar® commercial substrate and two species of eucalyptus (Eucalyptus citriodora and Eucalyptus urophylla), with four repetitions. At 75, 90 and 120 days after sowing (DAS) evaluated the stem diameter and plant height and at the end of the experiment (120 DAS) assessed fresh biomass of shoot and root, dry mass of shoot and root morphological parameters relative the plant height/stem diameter, dry mass of shoot/dry mass of roots and index of quality of Dickson. In general, the substrates that was added 7.5% of biochar promoted greater growth of seedlings, especially E. citriodora showed the best results for the evaluated characteristics. Evaluating the morphological parameters that act as key components in the quality of seedlings E. citriodora was superiors than E. urophylla. Concentrations of biochar above 30% harm the development of seedlings.

The aim of this paper was to assess the hygiene and sanitary profile of sun-dried meat sell points in the county of Cruz das Almas, Bahia. Four supermarkets, three food stores, two marketplace stallsand three butcher shops were researched, from December 2009 to January 2010. Data were collected by visiting, observing and the use of a checklist. From the places visited, only the supermarkets reached most of the evaluated parameters. In 50% of the sell points no refrigeration was used, and in 100% of them, the sun-dried meat was not packaged. In 75% of the establishments there was no exclusive knife to cut sun-dried meat, and in 25% of them food and money were handled simultaneously. Aprons, hairnets and clean closed-toe shoes were used in 25% of the sell points. No proper hand washing and others inadequate habits, such as chatting while handling and commercializing the product were in all the establishments. The sun-dried meat commercialized in the county does not comply with the Brazilian legislation, thus affecting food quality and putting at risk consumers' health, being necessary actions to qualify the workers involved in the handling of this food, as well a higher intervention of the responsible sanitary authority.

The aim was to evaluate the effect of late application of different nitrogen levels in different cultivars. The experimental design was a block design with four replications in a factorial 3 x 5 compounds by combining three soybean varieties: Conquest (early season), Pioneer 98C81 (medium cycle) and M-Soy 9350 (late maturity) and five nitrogen rates: zero, 20, 40, 80 and 160 kg ha-1 applied at growth stage R.1 (early flowering), using urea as nitrogen source. The application of 20 and 40 kg N ha-1 provided an increase in the number of pods per plant in all cultivars. Effect on thousand seed weight in cultivar checked only for conquest, with the application of 20 and 40 kg ha-1 N. Yield was reduced with application of 80 and 160 kg N ha-1 and increased with the application of 20 and 40 kg ha-1 N. There was a similar behavior among cultivars for yield components and yield when subjected to nitrogen in a late period. Although it was observed an increase in production around 300 kg ha-1, is still not economically viable application of nitrogen in soybean.

Seed treatment with insecticides is a routine practice that helps control initial field pests. However there is little information on the effects of insecticides on physiological quality of soybean seeds. Thus, this paper was to evaluate the effect of seed treatment with insecticides on the germination and vigor of soybean seeds. The design was completely randomized consisting of 7 treatments with 4 repetitions. The seeds of the cv. M-soy-6101 were treated with the insecticide thiamethoxam on the rate of 0.15 kg of a.i./100 kg of seeds, fipronil in the rate of 0.37 kg of a.i./100 kg of seeds, imidacloprido in the rate of 0,10 kg of a.i./100 kg of seeds; [thiodicarb + imidacloprid] at a rates of 0.14 + 0.13 kg of a.i./ha-1, carbofuran of rate 0.52 kg of a.i./100 kg of seeds, acephate at a rate of 0.75 kg of i.a./100 kg of seeds and a control without treatment. The variables analyzed were: germination, emergence speed, root length and seedling and percentage of normal seedlings in the accelerated aging. In the greenhouse (pot of 6 dm-3 of soil) were obtained levels of phytotoxicity, height and dry mass of shoots. Treatment with insecticides thiamethoxam, fipronil and imidacloprid provides adequate quality of the seeds and do not negatively affect the early development of plants. Insecticides [imidacloprid + thiodicarb], acephate and carbofuran affect the germination and vigor of soybean seeds.

With the purpose to minimize the incidence of stem-end rot, mango, caused by Lasiodiplodia theobromae, Fusicoccum aesculi, and Colletotrichum gloeosporioides, five resistance inductors were tested under field conditions: (T1) absolute control (no treatment); (T2) Fosetyl-AL; (T3) Agromós; (T4) Calcium Phosphite; (T5) Potassium Phosphite: (K30) and (T6) Acibenzolar-S-methyl; which were compared to the control treatment, to the conventional treatment on the farm (T7) compound: Pyraclostrobin; Thiophanate methyl; Azoxystrobin; Difeconazole; Tebuconazole; Thiabendazol; Tetraconazole. The sprayings were performed using a knapsack sprayer in a total of seven applications with 15-day intervals. The statistical design was a randomized block design with seven treatments and four replications, with each plant being considered a repetition, totaling 28 plants. Incidence of post-harvest rot was obtained for 77.9% of the treated fruit. No significant difference between the tested resistance inducers was observed, not even regarding the control. However, the conventional treatment (T7), adopted by the farm, showed a 25% disease incidence only and diverged statistically from the others. Studying the etiology of the rot, high indices of C. gloeosporioides, with 75% incidence, were verified, followed by L. theobromae, F. aesculi, A. niger and Alternaria sp, with incidence of 11%, 5.5%, 2.7% and 1.3%, respectively. Moreover, 4.3% of non-identified micro-organisms were detected.

The aim of this paper was to: a) verify if digital radiographic image measurements of G. biloba seeds could replace those obtained with a manual caliper; b) determine the degree of seed development through digitally measuring the air chamber of the seed and, c) make a radiographic pattern to characterize the seed species according to its anatomical and morphological structure, identify physical damage and characterize the species according to physical variables. In order to draw the radiographic patter, the seeds were submitted to different treatments: seed imbibition in rolled paper at 20 ºC for 48 hours; artificial damage by puncturing dry and imbibed seeds; artificial damage by fracturing dry and imbibed seeds. Seed anatomy structures were measured with a digital caliper and a manual caliper. The digital radiographic measurements could: a) replace the measurements taken with a manual caliper; b) obtain measurements that a manual caliper cannot supply; c) measure the air chamber in order to determine the level of seed filling; d) characterize the species by its anatomical and morphological structures, detect insect damage or fracture and make a radiographic pattern of G. biloba seeds.

The aim of this study is to evaluate the Sitophilus zeamais development in maize seeds, under four lightning systems and to find a mathematical model that describes the growth of this insect under the ambient conditions. Four wood cabinets were built, one of them was a natural light and the other ones as it follow: mixed light, sodium steam light and anti-bugs incandescent light. Inside each chamber, there were 18 recipients containing approximately 250g of seeds infested with 25 weevils. After the chambers building, a timer system was built, so the lamps would stay turned on always on the same time, from 6:00 p.m. to 6:00 a.m. to next day, consequently kept on for 12 hours. Every 21 days after the construction of the experiment 3 recipients from each chamber were taken off and weevils there were counted using the Belese funnel, and the seeds moisture was measured. It was not observed any influence on the bug development, who presented the maximum level of growing 84 days after the storage at all lightning systems tested. The humidity level kept constant itself until the 84th day and it had reduced significantly, indicating environmental changes during the procedure. The growth of S. zeamais can be described by a polynomial model.

To study plant growth and yield of cauliflower, two field trials were carried out: the first springsummer (Oct. 07, 2006 to Jan. 28, 2007) and the second autumn-winter (Apr. 04, 2007 to Jul. 09, 2007). The experimental design was randomized complete blocks in 4 x 4 factorial design with three replications. The following factors: line spacing (0.6, 0.8, 1.0 and 1.2 m) and plant spacing (0.4, 0.5, 0.6 and 0.7 m). The used cultivar was cv. Verona 284. The characteristics, number of leaves by plant, diameter of stem, diameter of inflorescence, inflorescence mass and yield were evaluated. With the reduction in spacing, were observed lower numbers of leaves, stem diameter, diameter and mass of the inflorescence, but there was an increase in yield. The maximum yield (23 t ha-1) was obtained with 0.6 x 0.4 m, ie, in higher plant population (41,667, plants ha-1).
