Because of the great diversity of corn genotypes and the effects of sowing seasons and nitrogenous fertilizers, in plant development, the identification of promising genotypes in these conditions allows you to provide information to determine the best strategies to be adopted in future breeding programs. Thus, this study aimed to effect of the genetic divergence among corn genotypes in different levels of nitrogen and sowing seasons in the State of Tocantins. In this sense, were conduced six maize populations of competition tests in Palmas-TO, distributed in two sowing seasons (01.21.2014 and 02.19.2014). In each sowing season, the essays were conduced under conditions of high nitrogen (N), mean and low N The experimental design used in each essay was a randomized block with three replications and 12 treatments. Genetic divergence was evaluated by method of Tocher. The characteristics ear weight with straw (Low N), humidity (Average N), number of grains in the row (High N), ear weight with straw (first and second sowing season), they are those that contributed for genetic divergence.

The genotypes present differential behavior as a function of genotype x environment interaction, having an effect on heritability estimation and selection gain. Thus, the present study was carried out with the objective of studying the interaction genotype x environment, for oil content in corn grains, as a function of nitrogen doses and sowing times. In the agricultural year 2015/16, six competition trials of maize genotypes were carried out in Palmas-TO, three of which were installed on 12.01.2015 and three on 01.01.2016. The trials were installed at two sowing times, and in each season, the genotypes were cultivated under conditions of low, medium and high nitrogen in coverage. The experimental design used in each trial was randomized blocks with 12 genotypes and three replicates. Analyzes of adaptability, stability, stratification and environmental dissimilarity were performed. The genotype GEN 12 is potentially promising for the oil content, being considered ideal by the methodology of Eberhart & Russel (1966). Evaluations of maize genotypes, carried out at different times under the same fertilization dose, provide similar results.

Pepper (Capsicum annuum L.) is a vegetable of great socioeconomic importance in Brazil. One of the main steps of the production system is the production of quality seedlings and for this a good quality substrate is necessary. Thus, the present study aimed to evaluate the development of pepper seedlings under different alternative substrates. The experiment was carried out following a completely randomized design with four replications. The 13 treatments were obtained in a 3x4+1 factorial; The first factor consists of three substrates: PlantHort II, III PlantHort (alternative) and the Plantmax® (commercial substrate) and the second factor comprises four levels of carbonized rice hulls in proportions of 0, 25, 50, 75% and additional treatment with 100% carbonized rice husk. Alternative substrates PlantHort II; PlantHort III was superior to the Plantmax® trade in plant height, root length, lap diameter, shoot dry mass, root dry mass, leaf number and dickson quality index. The alternative substrate PlantHort III provided a higher development quality index for sweet pepper seedlings in relation to the PlantHort II and Plantmax® substrates.
辣椒(Capsicum annuum L.)是巴西一种具有重要社会经济意义的蔬菜。生产系统的主要步骤之一是生产优质幼苗，为此需要优质的基质。因此，本研究旨在评价不同基质下辣椒幼苗的发育情况。试验采用完全随机设计，共4个重复。13个处理的阶乘为3x4+1;第一个因子由三种底物组成:PlantHort II, III PlantHort(替代)和Plantmax®(商业底物)，第二个因子包括四个水平的碳化稻壳，比例为0、25、50、75%，并使用100%碳化稻壳进行额外处理。备选基材PlantHort II;PlantHort III在株高、根长、圈径、茎干质量、根干质量、叶片数和叶片质量指数上均优于Plantmax®。与PlantHort II和Plantmax®基质相比，可选基质PlantHort III提供了更高的甜椒幼苗发育质量指数。

Industrial fish processing generates large quantities of protein-rich byproducts, which are usually discarded because of their low commercial value. It is therefore very important to find feasible alternatives to make use of this protein-rich raw material. The aim of this study was to obtain protein isolate from the byproducts of the fish hybrid sorubim ( Pseudoplatystoma reticulatum x Pseudoplatystoma corruscans ). After obtaining the fish protein isolate (FPI) from hybrid sorubim, the proximate composition of the raw material and of the isolate were determined and the functionality of the FPI was also evaluated. The mechanically separated meat (MSM) of hybrid sorubim contained 73.98% moisture, 37% lipids (dry basis-d.b.), 56.85% protein (d.b.) and 6.13% ash (d.b.). The protein isolate contained 5.61% moisture, 95.21% protein (d.b.), 3.06% lipids (d.b.) and 1.71% ash (d.b.). As for functionality, the isolate showed high solubility (88.5%), good water holding capacity (20.11 mL) and low oil holding capacity (2.03 mL). The process was considered efficient, in view of the high protein concentration and low moisture and lipids levels obtained in the isolate. The high water holding capacity and solubility confirm the promising potential of fish protein isolate from hybrid sorubim for use in the production of high added-value products.
工业鱼类加工产生大量富含蛋白质的副产品，这些副产品通常因其商业价值低而被丢弃。因此，寻找可行的替代品来利用这种富含蛋白质的原料是非常重要的。本研究的目的是从杂交鱼(Pseudoplatystoma reticulatum x Pseudoplatystoma corruscans)的副产物中获得分离蛋白。从杂交种sorubim中获得鱼蛋白分离物(FPI)后，对原料和分离物的近似组成进行了测定，并对FPI的功能进行了评价。杂种高粱机械分离肉(MSM)水分含量为73.98%，脂肪含量为37%(干基)，蛋白质含量为56.85%(干基)，灰分含量为6.13%(干基)。该蛋白分离物含水量为5.61%，蛋白质含量为95.21%，脂肪含量为3.06%，灰分含量为1.71%。功能性方面，该分离物具有较高的溶解度(88.5%)、良好的持水量(20.11 mL)和较低的持油量(2.03 mL)。考虑到在分离物中获得的高蛋白质浓度和低水分和脂质水平，该过程被认为是有效的。高保水能力和高溶解度证实了从杂交种中分离出的鱼蛋白在生产高附加值产品方面的巨大潜力。

This study investigated the overall migration from Poly (vinyl chloride) (PVC) polymer films into food simulants, after gamma irradiation ( 60 Co) or electron beam radiation. PVC polymer films containing di-(2-ethylhexyl) adipate (DEHA) and epoxidized soybean oil were stored under controlled temperature (24 ± 1 o C) and moisture (50 ± 5 %) for 2 days. These films were supported on a stainless-steel plates and specimens were subjected to ionizing radiation treatment with gamma radiation from a 60 Co source (dose rate = 20 Gy/min) or electron beam radiation (dose rate = 120 Gy/min) at absorbed doses equal to 0, 10, 25 and 50 kGy. Overall packing migrants were evaluated on different food simulants (distilled water, 3 % w/v acetic acid and 10 % v/v ethanol) as a function of time (24, 48 and 72 hours). Results of overall migration levels showed that the treatment with radiation doses above 10 kGy promoted a significant increase of the overall packing migrants levels into all aqueous food simulants (p < 0.05). Overall migration levels were also enhanced with increasing exposure time to food simulants.

The aim of the present study was to perform a review of the literature to provide a brief overview of the ecological aspects, diversity and potential biotechnological applications of endophytic fungi associated with economically important plants, such as the common bean ( Phaseolus vulgaris ), cocoa ( Theobroma cacao ) and soybean ( Glycine max ). A high diversity of fungi has been reported on the leaves, stems and other organs of such plants. Studies on this subject are of considerable importance and directly contribute to the knowledge and conservation of fungal biodiversity, especially in Neotropical areas. Furthermore, such studies can open the door to a wide range of potential uses and/or modulations of fungal microbiota with the aim of enhancing the health and productivity of plants in agricultural practices, such as promoting plant growth or the biological control of diseases caused by phytopathogenic microorganisms. These endophytic fungi also represent a valuable source for prospecting secondary metabolites for biotechnological purposes.

The artificial reservoir at Luiz Eduardo Magalhaes hydroelectric power plant, Tocantins River, is one of the most beautiful sceneries in Brazilian Amazon. The reservoir has clean, calm and warm water, being an inviting place to the practice of aquatic sports and recreation. This ecosystem is located in the Amazon region, where biodiversity is remarkable, including organisms that may cause harm to humans. The reservoir, for example, provides adequate environments to alligators, piranhas and poisoned stingrays. Although alligator’s attacks are very rare, piranha bites and stingrays stings are frequent. The reservoir is populated with several species of piranhas (e.g. Serrassalmus, Pygocentrus) and stingrays (e.g. Potamotrygon), 1 which are very abundant in shallow littoral areas, including sandy beaches used by local people and tourists. Piranha attacks usually cause small wounds, but stingrays may provoke serious injuries. Usually, the lesions caused by stingrays are very painful and involve edema and necrosis by poison 2,3. There is also risk of severe secondary infection by microbial population related to stingray's mucus. 4 Frequently, the injuries are compounded because the injured individual is not given proper first aids and does not seek medical help for appropriated care. 5 Thus, the total remission of symptoms can take months. The scientific literature and medical records describes many complex cases.

This ecosystem is located in the Amazon region, where biodiversity is remarkable, including organisms that may cause harm to humans. The reservoir, for example, provides adequate environments to alligators, piranhas and poisoned stingrays. Although alligator’s attacks are very rare, piranha bites and stingrays stings are frequent. The reservoir is populated with several species of piranhas (e.g. Serrassalmus, Pygocentrus) and stingrays (e.g. Potamotrygon), 1 which are very abundant in shallow littoral areas, including sandy beaches used by local people and tourists. Piranha attacks usually cause small wounds, but stingrays may provoke serious injuries. Usually, the lesions caused by stingrays are very painful and involve edema and necrosis by poison 2,3. There is also risk of severe secondary infection by microbial population related to stingray's mucus. 4 Frequently, the injuries are compounded because the injured individual is not given proper first aids and does not seek medical help for appropriated care. 5 Thus, the total remission of symptoms can take months. The scientific literature and medical records describes many complex cases.","PeriodicalId":119762,"journal":{"name":"Journal of Bioenergy and Food Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132028281","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Aim of this research was to study on effect of vacuum packaging on fatty acids profiles changes in Lathrinus microdon fish fillet during frozen storage up to 40 days. Palmitic acid (C16:0) and stearic acid (C18:0) were the major fatty acids among the SFAs during storage. Also lowest values of 0.263 % and 0.263% of cis-10-pentadecenoic acid (C15:1) were found in control samples and vacuum packaging, respectively. A decrease was observed in MUFA value with increased storage period in treatments (p<0.05). Oleic acid content (C18:1 n-9) in control (%23.64) and vacuum packaged samples (26.07%) was higher than that of other fatty acids. All samples showed a decreased PUFA value with increased storage (p<0.05). It can be concluded that packaging samples under vacuum and freezing conditions was a suitable way to reduce Shehri ( Lathrinus microdon ) fillet unsaturated fatty acids oxidation and to avoid them reduction, cause to extend their shelf life.
