In the first condition the germination behavior of the jabuticabeira seeds submitted to the hydrocondicionamento in different periods of time was evaluated, with influence of the storage temperature and the seed size. In the second, the behavior of seedlings submitted to water stress by means of different percentages of water in the substrate was observed, as well as, in flood condition of seedlings in water slides of five centimeters and stem height. Three experiments were carried out with seeds of jabuticabeira (Plinia sp.) Extracted from mature fruits, collected from a single plant of this institution. These seeds were hydrocondected for 0, 120, 240 and 360 hours at 5 ° C and 25 ° C (ambient) for the first experiment. In the second experiment, the seeds were separated in larger than 8 mm and smaller than 8 mm and hydrocondicionadas for periods of 0, 24, 48, 96 and 120 hours. The third experiment consisted of 24, 48, 72, 96, 120, 144, 168, 192, 216, 240, 264, 288, 312, 336, 360, 384, 408, 432, 456, 480 hours of water . After each period seeded Gerbox® box with lid, on moistened Germtest® paper, kept in controlled environment of 25 ºC. Seed germination (%), germination rate index (IVG) and mean germination time (TMG) were evaluated for 30 days after sowing of the three experiments. The second stage the experiments were carried out at UNEPE - Nursery Teaching and Research Unit of vegetable seedlings production and at the Laboratory of Plant Physiology, Federal University of Technology Paraná Câmpus Dois Vizinhos - Paraná. Jabuticaba saplings of four and 18 months were evaluated in relation to survival rate, leaf number, shoot height, stem diameter, and total dry matter mass (MST), total chlorophyll, quantum yield, protein content, total sugar and total phenols and proline in the field capacities of 100, 80, 60, 40, 20 and 0% and field capacity of 100, 75, 50, 25 and 0%, respectively. The seedlings were transplanted into 900 grams of commercially available substrate in transparent plastic bottles (PET®) with a capacity of two liters, without opening in the bottom for drainage of water and closed with aluminum foil to avoid evaporation of water from the substrate. In the third and fourth experiments, jabuticabeira seedlings of approximately 24 months and 18 months old were transplanted in plastic vats with a capacity of 3 liters, containing a substrate prepared in the proportion of 2: 1: 1 (v / v) of latosol, sand and poultry bed, respectively. After transplanting, the seedlings were submitted to flooding for periods of 0, 3, 5, 10 and 15 days and 0, 5, 10 and 15 days for the third and fourth experiments. Part of the plants will go through only one flood cycle and the remaining ones when 30 days have elapsed since they were removed by the same periods previously used. The variables evaluated for the third and fourth experiments were survival rate, leaf number, total plant height, stem diameter, root dry matter mass (MSR), shoot dry matter mass (MSPA) and mass of total dry matter (MST), Dickson quality index, total chlorophyll, quantum yield, protein, total sugar and total phenols and proline values. Seeds stored at 5 ° C had superior results for the percentage of germination and the mean time of germination when compared to those maintained during hydrocondicionamento at 25 ° C. When seeds larger than 8 mm were used, they were found to be viable for longer than the smaller ones. Seeds maintained in hydrocondicionamento for up to 456 hours maintained germination above 73%. The use of hydrocondicionamento in seeds of jabuticabeira helps in the process of maintenance of viability. Jabuticabeira seedlings submitted to different percentages of water in the substrate showed a lower survival rate when compared to seedlings submitted to flooding. The growth of jabuticabeira seedlings was not affected by the flood periods adopted. The quantum yield was equal to or below the threshold considered as damage of photosystem II, which is 0.80, demonstrating that under the conditions in which the seedlings were evaluated, the plants were not with the maximum production of photosynthesis. The biochemical variables, proteins, total sugars, total phenols and proline were not influenced by the percentage of water in the substrate, as well as for seedlings submitted to flooding with a water slide of five centimeters. In seedlings submitted to flood periods at the height of the cervix and with substrate water levels of 0, 25, 50, 75 and 100%, there was a change in proline content. Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) Este trabalho foi dividido em duas etapas, uma mais especificamente envolvendo o uso de sementes e a outra de mudas. Na primeira condição avaliou-se o comportamento germinativo das sementes de jabuticabeira submetidas ao hidrocondicionamento em distintos períodos de tempo, com influência da temperatura de armazenamento e do tamanho de semente. Na segunda observou-se o comportamento de mudas submetidas ao estresse hídrico por meio de diferentes porcentagens de água no substrato, bem como, em condição de inundação de mudas em lâminas de água de cinco centímetros e altura do caule. Foram realizados três experimentos com sementes de jabuticabeira (Plinia sp.) extraídas de frutos maduros, coletados de única planta da referida instituição. Estas sementes passaram por hidrocondicionamento durante 0, 120, 240 e 360 horas em temperatura de 5 ºC e 25 ºC (ambiente), para o primeiro experimento. No segundo experimento, as sementes foram separadas em maiores que 8 mm e menores que 8 mm e hidrocondicionadas por períodos de 0, 24, 48, 96 e 120 horas. O terceiro experimento, constituiu de sementes a hidrocondicionamento por 24, 48, 72, 96, 120, 144, 168, 192, 216, 240, 264, 288, 312, 336, 360, 384, 408, 432, 456, 480 horas. Após cada período semeadas em caixa Gerbox® com tampa, sobre papel Germtest® umedecido, mantido em ambiente controlado de 25 ºC. Durante 30 dias após a semeadura dos três experimentos, avaliaram-se a germinação das sementes (%), o índice de velocidade de germinação (IVG) e o tempo médio de germinação (TMG). A segunda etapa os experimentos foram realizados na UNEPE – Unidade de Ensino e Pesquisa Viveiro de produção de mudas hortícolas e no Laboratório de Fisiologia Vegetal, da Universidade Tecnológica Federal do Paraná Câmpus Dois Vizinhos – Paraná. Mudas de jabuticabeira de quatro e 18 meses foram avaliadas em relação a taxa de sobrevivência, número de folhas, altura da parte aérea, diâmetro do caule, e massa de matéria seca total (MST), clorofila total, rendimento quântico, teores de proteína, açúcar total e fenóis totais e prolina, nas capacidades de campo de 100, 80, 60, 40, 20 e 0% e capacidade de campo de 100, 75, 50, 25 e 0%, respectivamente. As mudas foram transplantadas em 900 gramas de substrato comercial alocado em garrafas de plásticos (PET®) transparentes com capacidade de dois litros, sem abertura no fundo para drenagem de água e fechados com papel alumínio para evitar a evaporação de água do substrato. No terceiro e quarto experimento, foram utilizadas mudas de jabuticabeira com idade de aproximadamente 24 meses e 18 meses, transplantadas em vasos plásticos com capacidade de 3 litros, contendo substrato preparado na proporção de 2:1:1 (v/v) de latossolo, areia e cama de aviário, respectivamente. Após o transplantio, as mudas foram submetidas a inundação por períodos de 0, 3, 5, 10 e 15 dias e de 0, 5, 10 e 15 dias, para o terceiro e quarto experimento. Parte das plantas passarão por apenas um ciclo de inundação e as demais quando passados 30 dias da sua retirada pelos mesmos períodos utilizados anteriormente. As variáveis avaliadas para o terceiro e quarto experimento foram taxa de sobrevivência, número de folhas, altura total da planta, diâmetro do caule, massa de matéria seca de raiz (MSR), massa de matéria seca da parte aérea (MSPA) e massa de matéria seca total (MST), índice de qualidade de Dickson, clorofila total, rendimento quântico, teores de proteína, açúcar total e fenóis totais e prolina. Sementes armazenadas em temperatura de 5 °C obtiveram resultados superiores para a porcentagem de germinação e o tempo médio de germinação quando comparadas a mantidas durante o hidrocondicionamento em temperatura de 25 °C. Quando utilizadas sementes maiores que 8 mm, verificou-se que as mesmas se mantem viáveis por mais tempo em relação as de menor tamanho. Sementes mantidas em hidrocondicionamento por até 456 horas mantiveram germinação acima de 73%. O uso do hidrocondicionamento em sementes de jabuticabeira auxilia no processo de manutenção da viabilidade. Mudas de jabuticabeira submetidas a diferentes porcentagens de água no substrato apresentaram taxa de sobrevivência menor quando comparadas a mudas submetidas a inundação. O crescimento das mudas de jabuticabeira não foi afetado pelos períodos de inundação adotados. O rendimento quântico ficou igual ou abaixo do limite considerado como de dano do fotossistema II, que é 0,80, demonstrando que nas condições em que as mudas foram avaliadas, as plantas não estavam com a produção máxima de fotossíntese. As variáveis bioquímicas, proteínas, açúcares totais, fenóis totais e prolina, não foram influenciadas pela porcentagem de água no substrato, bem como para mudas submetidas inundação com lâmina de água de cinco centímetros. Em mudas submetidas a períodos de inundação a altura do colo e com níveis de água no substrato de 0, 25, 50, 75 e 100%, houve alteração nos teores de prolina. 2021-04-19T11:54:41Z 2021-04-19T11:54:41Z 2019-04-01 doctoralThesis RADAELLI, Juliana Cristina.
