Autor(es): Sant’ana, Trícia Cavalcanti Pergentino de Abstract: The species Pogostemon cablin Benth. – Lamiaceae can be detached between the species of this genus because of the production of essential oil extracted from the dried leaves, which possesses medicinal, repellent and insecticide properties and is principally important for the perfume industry. The aim of this work was to install an Active Germplasm Bank of patchouli (Pogostemon sp.) at the Research Farm "Campus Rural da UFS", to evaluate the morphologic, agronomic and chemical characterization of the accessions, besides to test the influence of storage time of dry leaves on the essential oil content and chemical composition. The first chapter presents the general introduction, the literature review of botany and use of species of the genus Pogostemon, essential oil of P. cablin, conservation and morphological, agronomic and chemical characterization of vegetative germplasm, cultivation and post-harvest of P. cablin, and sustainability of agroecosystems. The second chapter presents and discusses the data of the morphological and agronomic characterization of 10 Pogostemon accessions of the Active Germplasm Bank (AGB) of the Universidade Federal de Sergipe (UFS) harvested in four seasons, may, august and november 2008 and february 2009. Variation between Pogostemon sp. accessions of the AGB of the UFS was observed for all qualitative morphologic characteristics. The descriptors color of stalks, veins, sepals and petals, and pilosity of leaves contributed to distinguish the accessions POG-001 and POG-006 from the others, which suggest that these two accessions are another species and not P. cablin. Significative differences between accessions were observed for the quantitative characteristics evaluated at each harvest, with exception for length of leaves (first harvest), essential oil yield (second harvest) and canopy diameter (third harvest). In the third chapter the chemical variation of the essential oil of 10 Pogostemon accessions of the AGB of the UFS, harvested in four seasons. Patchoulol was the major compound at the four harvests of all the P. cablin accessions. The principal compound of the accessions POG-001 and POG-006 was β-pinene. Two groups were detected by the multivariate analyses at the four harvests. Group 1 was formed by the accessions POG-001 and POG-006 (Pogostemon sp.), and group 2 was formed by the accessions of P. cablin (POG-002, POG-014, POG-015, POG-016, POG-017, POG-019, POG-021 and POG-022). In the fourth chapter the influence of storage time (0, 3, 7, 14 and 28 days) of dried leaves was analyzed on the essential oil content and chemical composition of two P. cablin accessions (POG-002 and POG-021) of the AGB of the UFS. Storage influenced significatively the essential oil content of accession POG-002. Patchoulol was the majority compound. Storage of dry leaves increased significatively the content of the compounds α-bulnesene (14 days) and germacrene A (3 and 7 days) at accession POG-021 and longicanfenilone (28 days), pogostol and patchoulol (3, 7, 14 and 28 days) at accession POG-002. However reduced significatively the content of the compounds cicloseichelene, β-cariofilene, α-guaiene, acifilene and α-bulnesene of the essential oil of the accession POG-002. 2009-06-25T00:00:00Z https://ri.ufs.br/jspui/handle/riufs/24445 Título: Comunidades de térmites em plantações de eucalipto no Litoral Norte da Bahia, Brasil Autor(es): Sales, Maria José Dias Abstract: Termites are insects best known for economic damage they cause, whether in urban areas, grassland or cropland, as sugar cane plantations and that the benefits they bring their activities to the ecosystems of which they belong. This study aimed to know the species of termites found in eucalyptus plantations of Copener Florestal Ltda, in order to contribute to knowledge about the termitofauna the region. The study was conducted in six areas recently harvested from Eucalyptus spp. of this company in december of 2005 through six transects following the protocol proposed by Jones and Eggleton (2000), which determines transects 100m long and 2m wide, divided into 20 plots (2 x 5m) contiguous. Each plot was sampled for 1 h / person and taken in each subdivision 12 soil samples from up to 10 cm deep, to collect termites. Were collected 35 species of termites belonging to 21 genera and two families, in a total of 826 samples in six areas, with five species occurred in all areas and 8 were exclusive. The family Termitidae represented 98.67% of samples and Rhinotermitidae only 1.33%. Ten species were dominant, all belonging to the family Termitidae. The dominant species belonging to the subfamily Apicotermitinae were: Anoplotermes sp.1, with a frequency of 15.3% and Anoplotermes sp.2, with 3.1%. In subfamily Termitinae were Amitermes amifer, with 14%; Microcerotermes sp. with 8.5%, and Termes sp. with 4% frequency. In subfamily Nasutitermitinae: Nasutitermes corniger, with 13.9% frequency; Diversitermes sp., whose frequency was 7.3%; Nasutitermes sp.1, with 5.1%; Velocitermes heteropterus with 4.4% and Constrictotermes cyphergaster, with 3.1% frequency. The functional group with the greatest number of species was consume humus, with 14 species and the number of samples of termites, wood feeders habit was superior to those of other functional groups (51.3%). The sampling effort was sufficient to collect most of the existing fauna of termites in their areas. The importance of this work stands out for its pioneering character on the north coast of Bahia and should be considered as a starting point for future studies of the termitofauna in eucalypt plantations in north coast of Bahia. 2010-03-25T00:00:00Z https://ri.ufs.br/jspui/handle/riufs/6649 Título: Utilização de doses reduzidas da eCG na indução de estro aplicadas pela via submucosa vulvar em ovelhas da raça Santa Inês Autor(es): Antunes, Karla Dias Abstract: The objectives were to improve the cost effectiveness of the technique of artificial insemination by transcervical fixed time (TAI) in sheep, testing the effect of dose reduction and use of the route submucosis (SMV) in the application of equine chorionic gonadotropin (eCG) on the efficiency of the synchronization protocol and fertility to artificial insemination (AI) and measure the stress level of the sheep as a result of the application of biotech. Were used six groups of twenty animals, where each group received doses of 200, 300 and 400 IU of eCG intramuscularly (IM) and SMV. Estrus was detected and made 48 hours after insemination by transcervical. Of the 120 treated ewes, 87.5% in estrus. The percentage of intra-uterine deposition of semen was 88.3%. Pregnancy rate ranged from 20 to 70% among the treatments, obtaining an average of 46.66%. The mean cortisol results were significant at 1.15, 2.86 and 0.52 μg/dL according to the three collections, being higher after the animal off the rack at the end of IA. The through SMV can be used to implement eCG at doses of 300 and 400 IU induction protocols and synchronizing estrus and ovulation in sheep associated TAI. The dose reduction to 200 IU eCG intramuscularly decreases the costs of maintaining the efficiency of estrus synchronization protocols and TAI showing better pregnancy rate and prolificacy in sheep, but should not be used route SMV. In general the procedures listed by the transcervical AI will cause stress in sheep. Although the technique of transcervical AI cause stress in animals produces satisfactory results in fertility multiparous ewes Santa Ines. 2012-04-27T00:00:00Z https://ri.ufs.br/jspui/handle/riufs/6648 Título: Controle alternativo da antracnose durante a pós-colheita de goiabas "Paluma" simulando armazenamento e a comercialização Autor(es): Oliveira, Lucas Fonseca Menezes Abstract: Brazil is one of the largest producers of fruit, guava with the culture of great importance in the diet of the population by having large amounts of vitamins, and carbohydrates and carotenoids. The postharvest of guava can be regarded as a problem for the broader participation of Sergipe in the marketing of this fruit in other parts of the country. The alternative control of fungal diseases plays an important role in the search for the most demanding consumer markets for healthy products and known origin. Thus the objective of this study was to develop and refine a technique that allows the storage of guavas for prolonged periods without the use of agrochemicals and excellent post-harvest quality in order to reduce costs and increase food security. Through the process of hydrodistillation essential oil was obtained from seeds of Shinus terebinthifolius from seeds and leaves and it was verified the oil yield in different periods of distillation and a period of 2.5 h distillation recommended for this plant. This had its chemical composition determined by analysis by gas chromatography, the components found in greater quantity in the oil were: ρ-Menth-1-en-9-ol, α-Thujene, β-pinene, Camphene, α - Fenchene , Terpinen-4-ol acetate, Bornyl Acetate, Cariophilene, Terpinen-4-ol, α-Terpineol, Germacrene - D, δ-cadinene, Hedycariol, α - Gurjunene, α-eudesmol, β-eudesmol. Petri dishes containing PDA culture medium supplemented with different concentrations of essential oil of S. terebinthifolius were inoculated with mycelial structures of the fungus Colletotrichum gloeosporioides for determining the lowest inhibitory concentration (MIC) of the oil on the mold where there is an efficiency of approximately 47% for controlling fungus at concentrations of 2%, 3%, 4%, 5% oil in the culture medium, as recommended concentration of 2% of essential oil in vivo tests. Guava fruit harvested at mature were inoculated with the fungus that causes anthracnose and treated with essential oil of aroeira da praia 3% being placed in low temperature (15 °C) and temperature (25 °C) in order to assess the period of storage and marketing guava and the development of the fungus against the essential oil. There was loss of weight in fruit and little variation in the amounts of soluble solids during the storage period. The guavas were already significant loss of firmness on the 5th day of storage. Significant change in the peel and pulp of guava during storage was an expected behavior for this variety of guavas. The essential oil delayed the appearance of characteristics of anthracnose lesions 3 days compared with the fungicide used in the experiment. It was demonstrated the accumulation of proline in the guavas during the post-harvest, indicating that the accumulation of proline may be related to weight loss and the development of anthracnose in guavas. 2012-04-25T00:00:00Z
