Diospyros ebenaster, originária do México e América Central, família Ebenaceae, é conhecida como sapota-preta. Os frutos podem ser consumidos in natura ou em sucos, como fonte de vitamina C. O objetivo deste trabalho foi caracterizar a morfologia do fruto, da semente e do processo germinativo da espécie. Os frutos foram caracterizados quanto à coloração, textura, consistência e teor de água no pericarpo, deiscência, massa, partes constituintes e dimensões. Para as sementes considerou-se: Massa, coloração, textura e consistência do tegumento, forma, presença e tipo de tecido de reserva e tipo, coloração, forma e posição do embrião. A descrição das plântulas foi realizada a partir da emissão da raiz primária até a expansão dos primeiros eófilos e início de fenecimento dos cotilédones. O fruto é carnoso, indeiscente, do tipo baga, polispérmico, globoso e achatado nos pólos. O epicarpo é liso, delgado e esverdeado. O comprimento médio dos frutos é 8,8 cm, o diâmetro médio 8,6 cm e a massa de 263 g. As sementes apresentam tegumento liso e cor castanho-médio. A massa de 100 sementes é 100,6 g. O comprimento médio das sementes é 2,2 cm, com 1,3 cm de largura. Possuem endosperma branco-Transparente e oleaginoso. O embrião é esbranquiçado e a germinação é epígea.

The objective of this study was to evaluate the performance, consumption and feed conversion of Angus x Nellore heifers fed hydrolyzed sugarcane. Twenty-four (1/2 Angus x Nellore crossbred) heifers were used with average body weight of 242 kg ± 23 kg, confined in individual pens with total area of 15 m2. The study consisted of six treatments distributed as follows: T1-in natura sugarcane: sugarcane was given to animals after being chopped; T2-hydrolyzed sugarcane with 0.5 % lime and 24 hours of air exposure; T3-hydrolyzed sugarcane with 0.5 % lime and 48 hours of air exposure; T4-hydrolyzed sugarcane with 1.0 % lime and 24 hours of air exposure; T5-hydrolyzed sugarcane with 1.0 % lime and 48 hours of air exposure; T6-hydrolyzed sugarcane with 1.0 % lime and 72 hours of air exposure. We used a completely randomized design with four replicates per treatment, and averages were compared by Tukey test at 5 % significant level of probability. No statistical difference was found for any of the treatments (P>0.05). The processing of sugarcane with lime did not increase the intake and performance of animals evaluated in this study.

The design and production process of the workshop shed made of bamboo presented in this paper is the result of almost two years of cooperation between Viverde Farmers Association, Universidade Estadual Paulista and Unisol. The system consists of rounded aroeira pillars, a roof structure formed by in natura bamboo frames and metal connections. The development of the parts and connections detailing, through the technical drawing of each component, enabled the development of standardized precision fittings aiming at optimizing the execution and saving time, energy and raw material on the assembly line. In this process, the creation and improvement of templates was necessary in order to facilitate the assembly of parts. The component assembly phases were recorded at the Experimental Laboratory for Bamboo and Wood Processing - UNESP/FEB. The results showed the good performance of the pre-fabrication process of bamboo components.
Chemical and biochemical characterization of guava and araçá fruits from different regions of Brazil
Resumo:
Guava and araçá, species of the Psidium genus, are important options for Brazilian agribusiness, especially the former species, due to their fruit characteristics, such as appearance, taste and richness in minerals and phenolic compounds. These fruits can be consumed in natura or in several processed forms. The active germplasm bank is an important tool for genetic resource characterization and plant breeding studies. Sixty guava and ten araçá accessions of the Psidium active germplasm, sampled in 44 different Brazilian regions and grown at Embrapa Semiarid, were chemically and biochemically characterized in order to support breeding programs. The accessions were grown in a randomized block design, with two replications and three plants/plot. The sugar, proteins, soluble solids, titratable acidity, calcium, magnesium, iron and phosphorus contents were determined. Large variations were observed in the analyzed compounds, which could be attributed to the diversity of genotypes and also to the environmental conditions, which affect the plant metabolism. The high variability observed in most parameters of the accessions is an important factor for the improvement of these species. Most guava accessions showed higher titratable acidity and soluble solids than those found in commercial cultivars and, in araçá, these levels were even higher, which makes them promising for commercial exploitation. Moreover, fruits of the guava and araçá accessions present good sources of sugars and minerals. Special attention should be given to some guava and araçá accessions from Maranhão and Pernambuco States, respectively, which showed high levels for titratable acidity, soluble solids, SS/TA ratio, total soluble sugars, calcium, magnesium and iron, should be targets of breeding programs for new Psidium cultivars. © ISHS.
