O delineamento experimental foi inteiramente casualizado em esquema fatorial 5 x 5 x 5 (potenciais osmóticos x concentrações do regulador x teores de água) + testemunha, totalizando 126 tratamentos, com 4 repetições de 20 sementes por parcela. As sementes com o teor inicial de 10% de água foram condicionadas nos potenciais 0, -0,3, -0,6, -0,9 e -1,2 MPa (Polietileno Glicol 6000) associados com as concentrações de 0, 250, 500, 750 e 1000 mg L-1 de GA3 até a obtenção dos teores de 15, 20, 25, 30 e 35% de água, sob temperatura constante de 25°C ± 2°C. As variáveis analisadas foram porcentagem de germinação, velocidade e tempo médio de germinação, sincronização da germinação, teores de açúcares solúveis totais e perfil dos açúcares por HPLC. Para a análise de açúcares solúveis foram selecionadas as sementes condicionadas nos potenciais osmóticos 0, -0,3, -0,6, -0,9 e -1,2 MPa até obtenção dos diferentes teores de água sem o emprego de GA3 e as sementes hidrocondicionadas (0 MPa) com o emprego das concentrações de 0, 250, 500, 750 e 1000 mg L-1 de GA3, até a obtenção dos diferentes teores de água. Verificou-se que o condicionamento das sementes de Annona emarginata (Schltdl.)

Seeds with 10% of initial water content were submitted to priming at 0, -0,3, -0,6, -0,9 e -1,2 MPa (Polyethylene glycol 6000), associated with concentrations 0, 250, 500, 750 e 1000 mg L-1 of GA3 until they achieved 15, 20, 25, 30 e 35% of water content, at constant temperature of 25°C ± 2°C. The variables analyzed were germination percentage, speed and average time of germination, synchronization of germination, total soluble sugar content and profile of sugars by HPLC. For soluble sugars analysis we selected seeds conditioned in water potential 0, -0,3, -0,6, -0,9 and -1,2 MPa until obtain different water content without the use of GA3 and hydroprimed seeds (0 MPa) with the use of concentrations 0, 250, 500, 750 and 1000 mg L-1 of GA3, until they obtained different water contents. We found that priming of Annona emarginata seeds at different osmotic potential associated with GA3 concentrations, until different water content were obtained, promote alterations in the germination and soluble sugars content.

Thesis (MScAgric)--Stellenbosch University, 2003. / ENGLISH ABSTRACT: 1. The effect of heat-treatment and dehulling of full-fat soya (Glycine max) on AMEn' amino acid availability and broiler performance. Heat treatment and dehulling of full-fat soya were evaluated in terms of their effect on AMEn, apparent amino acid availability and broiler performance. Four products were tested: raw whole soya (RWS), raw dehulled soya (RDS), extruded whole soya (EWS) and extruded dehulled soya (EDS). Trials were conducted to determine AMEn values and apparent amino acid availability of the products. A 42-day broiler trial was conducted to measure the effect of extrusion and dehulling on broiler performance. Test products were added to the diets at levels up to 263.2 g/kg in the starter diet and 260.0 g/kg in the finisher diet. Results indicated that extrusion cooking improved AMEn and apparent amino acid availability. This was reflected in the improved performance of broilers fed extruded soya as compared to raw soya. Increasing amounts of RWS and RDS led to decreases in mass and intake and poor feed conversion ratio (FeR) due to the presence of anti-nutritional factors. Broilers fed EWS were heavier, consumed more feed and had better FeR than those fed RWS or RDS. Dehulling improved AMEn (EWS: 13.75 MJ/kg vs EDS: 15.09 MJ/kg) and rendered a product with slightly higher levels of total amino acids. Broiler performance did not reflect this as there was no difference in mass, intake or FeR between broilers fed increasing levels of EWS or EDS. Lysine and arginine were less available in EDS than EWS indicating the possible over-cooking of EDS. Levels of EWS and EDS of 263.2 g/kg in the starter and 260.0 g/kg in the finisher supported maximum broiler performance. 2. The effect of heat-treatment and dehulling of full-fat sunflower (Helianthus annuus) on AMEm amino acid availability and broiler performance. Heat treatment and dehulling of full-fat sunflower were evaluated in terms of their effect on AMEn, apparent amino acid availability and broiler performance. Four products were tested: raw whole sunflower (RWSF), raw dehulled sunflower (RDSF), extruded whole sunflower (EWSF) and extruded dehulled sunflower (ED SF). Trials were conducted to determine AMEn values and apparent amino acid availability of the products. A 42-day broiler trial was conducted to measure the effect of expansion and dehulling on broiler performance. Test products were added to the diets at levels up to 115.0 glkg in the starter diet and 181.5 glkg in the finisher diet. Dehulling rendered a product with higher crude protein, ether extract, amino acid and AMEn values. AMEn was only slightly improved by expansion. The AMEn values obtained were: RWSF: 16.03 MJ/kg, RDSF: 18.87 MJ/kg, EWSF: 16.22 MJ/kg, EDSF: 19.49 MJ/kg. Dehulling had no effect on apparent amino acid availability. Expansion did not affect apparent amino acid availability of dehulled full-fat sunflower but had a negative influence on apparent amino acid availability of whole sunflower seeds. This highlights the possible dangers of reduced protein quality as a result of overprocessing. No differences were observed in terms of mass, intake and feed conversion ratio of broilers fed any of the products during the 42-day broiler growth trial. All products supported optimum broiler performance at levels up to 115.0 glkg in the starter diet. For the finisher diets, optimum performance was maintained at levels of 181.5 glkg, for RDSF and EDSF, while performance of broilers fed RWSF and EWSF was optimal up to 145.2 glkg. / AFRIKAANSE OPSOMMING: 1. Die invloed van hitte-behandeling en ontdopping van volvetsojabone (Glycine max) op SMEm skynbare aminosuur beskikbaarheid en braaikuikenprestasie. Hitte-behandeling en ontdopping van volvetsojabone is ge-evalueer in terme van hul invloed op stikstof gekorrekteerde skynbare metaboliseerbare energie (SMEn) waardes, skynbare aminosuur beskikbaarheid en braaikuikenprestasie. Vier produkte is getoets: rou heel sojabone (RWS), rou ontdopte sojabone (RDS), geekstrueerde heel sojabone (EWS) en geekstrueerde ontdopte sojabone (EDS). Proewe is uitgevoer om die SMEn waardes en skynbare aminosuur beskikbaarheid van die vier produkte te bepaal. Gedurende 'n braaikuikengroeitoets van 42 dae is die invloed van hittebehandeling (ekstrusie) en ontdopping op braaikuikenprestasie gemeet. Die vier toetsprodukte is ingesluit in die aanvangsdieet teen peile van tot 263.2 g/kg en teen peile van tot 260.0 g/kg in die afrondingsdieet. Resultate het getoon dat ekstrusie die SMEn waardes en skynbare aminosuur beskikbaarheid verbeter het. Braaikuikens wat geekstrueerde soja ontvang het, het beter gepresteer as braaikuikens wat rou soja ontvang het. Verhoogte insluitings van RWS en RDS het gelei tot verlagings in massa toename en voerinname en swak voeromsetverhoudings (VOV), as gevolg van die teenwoordigheid van anti-voedings faktore. Braaikuikens wat EWS ontvang het, was swaarder, het meer ingeneem en het beter vav gehad as die wat RWS of RDS ontvang het. Ontdopping het SMEn verhoog (EWS: 13.75 MJ/kg vs EDS: 15.09 MJ/kg) en ontdopte produkte het klein hoeveelhede meer aminosure bevat. Dit het egter nie in braaikuikenprestasie gewys nie. Daar was geen verskille in massa, voerinname en vav tussen braaikuikens wat EWS of EDS ontvang het. Lisien en arginien was minder beskikbaar in EDS as EWS wat op die moontlike oorprosessering van EDS dui. Vlakke van EWS en EDS van 263.2 g/kg in die aanvangsdieet en 260.0 g/kg In die afrondingsdieet het maksimale braaikuikenprestasie ondersteun. 2. Die invloed volvetsonneblosaad van hitte-behandeling (Helianthus annuus) en ontdopping van op SMEo, skynbare aminosuur beskikbaarheid en braaikuikenprestasie. Hitte-behandeling en ontdopping van volvetsonneblomsaad is geevalueer in terme van hul invloed op stikstof gekorrekteerde skynbare metaboliseerbare energie (SMEn) waardes, skynbare aminosuur beskikbaarheid en braaikuikenprestasie. Vier produkte is getoets: rou heel sonneblomsaad (RWS), rou ontdopte sonneblomsaad (RDS), geekspandeerde heel sonneblomsaad (EWS) en geekspandeerde ontdopte sonneblomsaad (EDS). Proewe is uitgevoer om die SMEn waardes en skynbare aminosuur beskikbaarheid van die vier produkte te bepaal. Gedurende 'n braaikuikengroeitoets van 42 dae is die invloed van hitte-behandeling (ekspansie) en ontdopping op braaikuikenprestasie gemeet. Die vier toetsprodukte is ingesluit in die aanvangsdieet teen peile van tot 115.0 g/kg en teen peile van tot 181.5 g/kg in die afrondingsdieet. Ontdopte sonneblomsaad het hoer peile van ruproteien, eter-ekstrak en aminosure as heel sonneblomsaad. SMEn waardes is ook hoer vir ontdopte sonneblomsaad. Hitte-behandeling het SMEn waardes effens verhoog. Die bepaalde SMEn waardes is as volg: RWSF: 16.03 MJ/kg, RDSF: 18.87 MJ/kg, EWSF: 16.22 MJ/kg, EDSF: 19.49 MJ/kg. Ontdopping het geen invloed op skynbare aminosuur bekikbaarheid gehad nie. Skynbare aminosuur beskikbaarheid van ontdopte sonneblomsaad IS me deur hitte-behandeling beinvloed nie, terwyl die van heel sonneblomsaad negatief beinvloed is. Dit beklemtoon die gevare van verswakte proteien kwaliteit as gevolg van oor-prosessering. Geen verskille is opgemerk in terme van massa, voerinname en voeromset verhouding (VOV) tussen die vier produkte gedurende die braaikuikengroeitoets van 42 dae. Alle produkte het maksimale braaikuiken prestasie ondersteun in die aanvangsdieet teen vlakke van 115.0 g/kg. In die afrondingsdieet het RDSF en EDSF optimale braaikuikenprestasie onderhou teen vlakke van 181.5 g/kg, terwyl RWSF en EWSF net t

Apesar da crescente utilização dessa tecnologia pelas empresas produtoras de sementes nos últimos anos, poucas são as informações publicadas em relação ao comportamento de sementes revestidas durante o período de armazenamento. Os experimentos foram realizados na Faculdade de Engenharia Agrícola - FEAGRI/UNICAMP, com o objetivo de obter informações adicionais sobre a qualidade fisiológica de sementes de Brachiaria humidicola (Rendle) Schweick e Brachiaria brizantha (Hochst. ex A. Rich.) Stapf, submetidas a diferentes tratamentos. No início e após 45, 90, 135, 180, 270 e 360 dias de armazenamento nas temperaturas ambiente, 30°C e 40°C, as sementes foram submetidas às avaliações do grau de umidade (U), germinação (G), viabilidade-tetrazólio (TZ), envelhecimento acelerado (EA), primeira contagem de germinação (1ªCG), emergência das plântulas em areia (E), comprimento da parte aérea das plântulas (CPA), índice de velocidade de emergência (IVE), peso seco da plântula (PSP), peso de mil sementes (PMS) e atividade de água (Aw). Foi utilizado um delineamento inteiramente casualizado, com quatro repetições por tratamento e três temperaturas de armazenamento. A análise estatística foi realizada através do teste de Tukey para comparação das médias, em nível de 5% de probabilidade. Na avaliação do início do período de armazenamento as sementes tratadas tiveram resultados em valores absolutos superiores à testemunha, com superação da dormência para as duas espécies, sem diferenças estatísticas significativas. As sementes incrustadas tiveram redução acentuada do seu grau de umidade, com média de 2,80 para Brachiaria humidicola e de 2,90 para Brachiaria brizantha ao longo do armazenamento. Os maiores porcentuais de germinação ocorreram em períodos distintos para as espécies, aos 270 dias para Brachiaria humidicola e aos 135 dias para Brachiaria brizantha. A escarificação química das sementes com ácido sulfúrico é uma alternativa de tratamento se a intenção for realizar a semeadura até 45 dias após a colheita. Para armazenamento por períodos mais longos, a técnica de revestimento por incrustação é uma importante alternativa, pois não prejudica a germinação e permite a adição de diversos produtos químicos à semente, aumentando o seu valor agregado / Abstract: The coating is to be a major technological breakthrough in the production of seeds, including grasses.

The seeds were evaluated by moisture content, germination, feasibility-tetrazolium, accelerated aging, first count germination, seedling emergence in sand, seedling length, speed of emergency index, seedlings dry weight, thousand seeds weight and water activity. A completely randomized design with four replications per treatment and three storage temperatures. Was used statistical analysis was performed using the Tukey test at 5% probability. The assessment at the beginning of storage the treated seeds were found to have absolute values greater than control, with dormancy for both species, no statistically significant differences. The incrusted seeds were embedded substantially reducing the moisture content, averaging 2.80 for Brachiaria humidicola and 2.90 for Brachiaria brizantha during storage. The highest percentage of germination occurred at different times for the species, to 270 days for Brachiaria humidicola and 135 days for Brachiaria brizantha. The chemical scarification of seeds with sulfuric acid is an alternative treatment if the intention is either to sow until 45 days after harvest. To store for longer periods, the technique of incrusting is an important alternative, since not affect the germination and allows the addition of various chemicals to the seed, increasing its aggregate value / Doutorado / Tecnologia Pós-Colheita / Doutor em Engenharia Agrícola

As principais estratégias para a conservação dessas sementes durante o armazenamento consistem na desidratação parcial, na adição de ácido abscísico, no uso de solução de polietileno glicol e de baixas temperaturas. Contudo, tais condições ainda podem conduzir à deterioração, tanto pela atividade do seu próprio metabolismo, como pelo desenvolvimento de micro-organismos favorecidos pela umidade. Desta forma, o presente trabalho teve como objetivo analisar o grau de interferência dos fungos no metabolismo respiratório dos embriões de Inga vera com diferentes níveis de hidratação e a eficiência do tratamento com fungicidas, visando à manutenção da viabilidade durante o armazenamento. Para tanto, os embriões foram obtidos em três anos, sendo em 2009 colhidos em duas fases distintas de maturação (imaturos e maduros), submetidos a dois níveis de secagem, tratados ou não com carboxin + thiram e armazenados sob 7 e 25 oC por até 65 dias. Em 2010, foram colhidos maduros, submetidos a quatro níveis de secagem, tratados ou não com carbendazin + thiram e armazenados a 7 ºC por 120 dias. Nos experimentos de avaliação da respiração, os embriões obtidos em 2010 foram tratados ou não com carbendazin + thiram, mortos ou não por congelamento e inoculados ou não com Aspergillus flavus. Os colhidos em 2011 foram mantidos sem secagem e tratados ou não com carbendazin + thiram e a respiração foi avaliada a 7 e a 25 ºC. Constatou-se que a incidência de fungos, principalmente Fusarium oxysporum, juntamente com o teor de água e a temperatura influenciam nas taxas respiratórias dos embriões de I. vera maduros e que o tratamento com carbendazin + thiram, na dose de 80 mL do produto comercial para 100 kg de embriões, é eficiente na manutenção da viabilidade de embriões maduros e sem secagem, a 7 ºC por 120 dias. Pestalotiopis sp., Phoma sp., Phomopsis diachenii e Colletotrichum gloeosporioides aparecem durante o armazenamento, simultaneamente à deterioração dos embriões de I. vera. O desenvolvimento de fungos em embriões de I. vera difere do padrão clássico definido com base em sementes ortodoxas / Abstract: The high metabolism hinders the maintenance of Inga vera seeds viability. The main strategies for the conservation of these seeds during storage consist of the partial dehydration, addition of abscisic acid, use of polietileno glicol solution and of low temperatures. However, such storage conditions can lead to further deterioration of the seed, either by the activity of its own metabolism, as the development of microorganisms favored by moisture. This study aimed to analyze the degree of interference of fungi on the respiratory metabolism of Inga vera embryos with different levels of hydration and the efficiency of fungicide treatment, as maintaining these embryos viability during storage. The embryos were obtained in three years. In 2009 they were collected in two distinct stages of maturation (immature and mature), subjected to two drying levels, treated or not treated with carboxin + thiram and stored at 7 and 25 º C for up to 65 days. In 2010 the embryos were collected mature, subjected to four drying levels, treated or not treated with carbendazin + thiram and stored at 7 º C for 120 days. In the experiments carried out to evaluate the respiration, the embryos obtained in 2010, were treated or not treated with carbendazin + thiram, killed or not by freezing and inoculated or not with Aspergillus flavus. The embryos collected in 2011 were kept without drying, treated or not treated with carbendazin + thiram and respiration was evaluated at 7 and 25 ° C. It was found that the incidence of fungi, primarily Fusarium oxysporum, together with the water content and temperature influence respiration rates of mature embryos of I. vera and that the treatment with carbendazin + thiram at the dose of 80 mL of the commercial product to 100 kg of embryos is effective for maintaining the viability of mature embryos without drying at 7 ° C for 120 days. Pestalotiopis sp., Phoma sp., Phomopsis diachenii and Colletotrichum gloeosporioides are detected during the storage time, along with the deterioration of the embryos of I. vera. The development of fungi on embryos of I. vera differs from the classic pattern verified for orthodox seeds / Doutorado / Tecnologia Pós-Colheita / Doutor em Engenharia Agrícola
