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).

Cubiu is a native Amazon plant that has attracted attention for its nutritional and pharmaceutical industries. The goal this paper was to evaluate the effect of priming on germination andseedling emergence from of three varieties of cubiu seeds: Santa Luzia, Thais and Musquet, using five priming conditions: water for 12 and 24 h, solutions of PEG 6000 and 0.35 Mol KNO3 for 24 and 48 h at 25 °C. Unprimed seeds were considered as control. After priming, seeds conditioned or not, were evaluated by means of tests: germination, speed of germination, seedling emergence and speed of emergence. The variety Thais had the best physiological quality, and priming in KNO3 which provided greater effects on germination and seed vigor cubiu.

The objective of this research was to evaluate the color of tomatoes coated with different concentrations of pectin during storage at room temperature. Were used tomatoes with color greenish-pink divided into four lots: uncoated tomatoes (CT) and covered with biofilms with 2% (P2), 5% (P5) and 8% (P8) of solution of pectin. Initially it was evaluated the rind of tomatoes, then these were cut in half and it was evaluated the pulp (fleshy part), subsequently the two parts of tomatoes were processed in a blender to yield the processed pulp, which also was evaluated. Evaluations were done at 0, 2, 4, 7, 11 and 16 days storage with analysis of luminosity (L*), intensity of red (+a*) and intensity of yellow (+b*) in portable spectrophotometer. It was observed in all treatments that the rind and the fleshy and processed pulp showed a reduction in the values of L*. At the end of the storage, the treatment CT showed the highest values +a* for the rind and the fleshy and processed pulp, followed of the treatments P2, P5 and P8, respectively. The values of +b* decreased in the rind and in processed pulp of the CT and P2 treatments, but increased in the P5 and P8 treatments. It is concluded that the use of edible coatings pectin is effective to retard development of coloration typical of ripe tomato, results to be associated with the evaluation of physical and chemical parameters for a respect to retardation of the ripening.

The caatinga vegetation has many physiognomies and in a general way is degraded by human pressure, so it is important to characterize phytosociologically its various facies. This study aimed to characterize the composition and structure of the woody component of a relatively homogeneous remnant of caatinga vegetation in semiarid region of Paraiba, in a region locally called as Seridó. We sampled all shrub-tree species, alive or dead, still foot, with basal circumference > 10 cm (at 30 cm from the base) and total height > 1m. Ten plots of 20 x 20 m were allocated, randomly distributed across the study area. The total density was 1622.5 ind./ha, distributed in 21 species, 21 genera and 11 botanical families. The main species, according to the index of importance value were Poincianella pyramidalis (Tul.) L.P. Queiroz, Aspidosperma pyrifolium Mart., Commiphora leptophloeos (Mart.) J.B. Gillett and Anadenanthera colubrina (Vell.) Brenan. Despite being an area that is considered well preserved within the region, the studied community has a high density of individuals with small diameter shafts (D0,3 ¿ 6 cm) (63%). The Shannon index (3.38) may be considered medium and the Pielou equability (0.85) indicates floristic heterogeneity of the shrub-arboreal component. The floristic composition and species richness are similar to those found in other studied areas of the region, except by the high abundance of Commiphora leptophloeos and Amburana cearensis (Allemão) A.C.
