Resumo: The present study aimed to generate information about the morphology of fruits, seeds, seedlings, germination phases and categories of normal and abnormal seedlings of P. bracteosa, P. gardnerian and P. pyramidalis; establish the most appropriate procedure for determining the moisture content of the seeds of the studied species; recommend pre-germination treatment to overcome dormancy of seeds of species; establish the optimum conditions of substrate temperature, photoperiod and levels of moistening of paper substrates and vermiculite for use in germination and seed vigor of the species and to evaluate the effects of different substrates, containers and shading levels on the production of seedlings of the species under study. For that were made descriptions and illustrations of the morphological characteristics of fruits, seeds, seedling and germination stages. For determination of water content was measured using the method oven at 105±3°C for 24 hours, with samples of seeds of different weights 5, 10 and 15 g and using different aluminum capsules (6 cm diameter x 5 cm height) and (8 cm diameter x 3 cm height). To break dormancy of seeds, and the control (no treatment), were performed the following treatments: soaking in water for 24 hours, soaking in water at 80ºC until it reaches room temperature; scarification n°. 100 for mass at the opposite the hilum; scarification n°. 100 for mass followed by soaking in water for 24 hours; chemical scarification with concentrated sulfuric acid for 30 seconds, 1, 5 and 10 minutes. The performance germination and vigor were also evaluated by subjecting the seeds at different temperatures and substrates. To review the photoperiod, the seeds of the species P. gardneriana, were subjected to continuous light, continuous dark, photoperiod of 12 hours light and 12 hours of dark and light and photoperiod of 8 hours light and 16 hours of dark, at constant temperature of 25ºC. In testing the germination and vigor, to evaluate the different levels of water for moistening of the substrate, the seeds of P. bracteosa were sown between a sheet of blotting paper and paper towel moistened in the substrates being equivalent to 2,0; 2,5; 3,0 and 3,5 times the weight of dry substrates. The seeds of P. bracteosa also were sown in vermiculite medium, moist equivalent of 50, 60, 70 and 80% of water holding capacity. The seedlings of the species studied were grown in nursery conditions, testing substrates are semi-fine vermiculite + manure; Tropstrato® + manure, coir dust + manure and sugarcane bagasse + manure in different containers: polyethylene bag and cartridge in different shading levels: full sunlight (0%) and ambient shading in the proportions 30%, 50% and 70%. The variables evaluated were: germination (%), first count (%), germination speed index, length of the primary root and shoot and root dry mass and shoot. The results showed that the fruit of P. bracteosa and P. gardneriana are dried, simple, kind and legume seeds of both species are stenospermics, epigeal germination and seedling phanerocotylar. For more accurate determination of moisture content of seeds of the species P. bracteosa capsules are recommended 6 x 4 cm) and 8 x 3 cm using samples of 5 or 15 g of seed; to P. gardneriana containers are the most suitable for 6 x 4 cm and 8 x 3 cm and seed samples 5, 10 and 15 g, except for sample 15 g and the container 6 x 4 cm, while for P. pyramidalis, it is recommended that the weight of the seed sample 15g and container of 6 x 4 cm. The seeds of P. bracteosa and P. pyramidalis not require the use of pre-germination treatments to overcome dormancy and chemical scarification of the seeds of P. gardneriana sulfuric acid for one minute is the most efficient method. The constant temperature of 25°C and vermiculite, and 20°C and the substrate blotting paper, and 10 and 15°C with the substrate paper towel are recommended for testing of germination and vigor of P. bracteosa. The seeds of P. gardneriana showed high germination and vigor when subjected to constant temperatures of 25 and 30ºC and plated on substrates sand and vermiculite, 20°C when kept in sugarcane bagasse and 10°C on the paper towel and the alternating temperature of 20-30ºC and coconut coir substrate. The best conditions for performance evaluation germination and vigor of P. pyramidalis are the constant temperatures of 30ºC and the mixture of sand and sugar cane bagasse, 25°C, combined with vermiculite and 20°C, along with sand and paper towels. The seeds of P. gardneriana behaved as neutral photoblastic in laboratory condition at 25ºC. The seeds of P. bracteosa kept the substrate moistened with water volume of 3,5 times the weight of blotter paper and paper towel dried showed higher vigor. The vermiculite moistened with water at 60, 70 and 80% capacity retention of the substrate can be used in the germination and vigor of P. bracteosa. For the production of seedlings of P. bracteosa should be used vermiculite substrates + manure or Tropstrato® + manure in plastic bags and kept in the greenhouse with shade screen 50%. The plastic bags combined with manure + vermiculite in a greenhouse with 30% shade screen and substrate Tropstrato® + manure in full sun environment can be recommended for seedling production P. gardneriana. The best conditions for production of seedlings of P. pyramidalis are manure + vermiculite in plastic bags and protected environment with 70% shade screen and substrate Tropstrato® + manure in tubes, kept in the greenhouse with shade screen 50%.

Para isso foram feitas descrições e ilustrações das características morfológicas dos frutos, sementes, plântula e fases de germinação. Para determinação do teor de água, foi utilizado o método de estufa a 105±3ºC, por 24 horas, com amostras de sementes de diferentes pesos 5, 10 e 15 g e a utilização de diferentes cápsulas de alumínio (6 cm de diâmetro x 5 cm de altura e de 8 cm de diâmetro x 3 cm de altura). Para superação da dormência das sementes, além da testemunha (sem nenhum tratamento), foram realizados os seguintes tratamentos: embebição em água fria por 24 horas; embebição em água a 80ºC até atingir a temperatura ambiente; escarificação com lixa nº 100 para massa na parte oposta ao hilo; escarificação com lixa nº 100 para massa, seguida da embebição em água por 24 horas; escarificação química com ácido sulfúrico concentrado, durante 30 segundos, 1, 5 e 10 minutos. O desempenho germinativo e vigor também foram avaliados, submetendo-se as sementes a diferentes temperaturas e substratos. Para avaliação do fotoperíodo, as sementes da espécie P. gardneriana, foram submetidas à luz contínua, escuro contínuo, fotoperíodos de 12 horas com luz e 12 horas de escuro, 8 horas com luz e 16 horas de escuro, sob temperatura constante de 25ºC. Na realização do teste de germinação e vigor, para avaliar os diferentes níveis de água para umedecimento do substrato, as sementes de P. bracteosa foram semeadas entre uma folha de papel mata-borrão e papel toalha, sendo os substratos umedecidos no equivalente a 2,0; 2,5; 3,0 e 3,5 vezes o peso dos substratos secos. As sementes de P. bracteosa também foram semeadas entre vermiculita média, umedecida no equivalente a 50; 60; 70 e 80% da capacidade de retenção de água. As mudas das espécies estudadas foram produzidas em condições de viveiro, testando-se os substratos vermiculita semifina + esterco; Tropstrato® + esterco; pó de coco + esterco bovino; e bagaço de cana + esterco, em diferentes recipientes: saco de polietileno e tubete, em diferentes ambientes: pleno sol (0%) e ambiente sombreamento nas proporções 30%, 50% e 70%. As variáveis avaliadas foram: germinação (%), primeira contagem de germinação (%), índice de velocidade de germinação, comprimento da raiz primária e parte aérea e massa seca do sistema radicular e parte aérea. Os resultados permitiram concluir que os frutos de P. bracteosa e P. gardneriana são secos, simples, do tipo legume e as sementes de ambas espécies são estenospérmicas com germinação do tipo epígea e plântula fanerocotiledonar. Para determinação mais precisa do grau de umidade de sementes das espécies P. bracteosa são recomendadas as cápsulas de 6 x 4 cm e 8 x 3 cm utilizando-se amostras de 5 ou 15 g de sementes; para a P. gardneriana os recipientes mais adequados são os de 6 x 4 cm e 8 x 3 cm e amostras de sementes de 5, 10 e 15 g, com exceção da amostra de 15 g e o recipiente 6 x 4 cm; enquanto para P. pyramidalis, recomenda-se o peso da amostra de sementes de 15g e o recipiente de 6 x 4 cm. As sementes de P. bracteosa e P. pyramidalis não necessitam da utilização de tratamentos pré-germinativos para superação da dormência e a escarificação química das sementes de P. gardneriana com ácido sulfúrico por um minuto é o método mais eficiente. As temperaturas constantes de 25°C e o substrato vermiculita, e de 20°C e o substrato papel mata-borrão, e de 10 e 15ºC juntamente com o substrato papel toalha são recomendadas para realização dos testes de germinação e vigor das sementes de P. bracteosa; As sementes de P. gardneriana demonstraram alta germinação e vigor quando submetidas às temperaturas constantes de 25 e 30ºC e semeadas nos substratos areia e vermiculita, 20°C quando mantidas no bagaço de cana e na de 10°C no papel toalha e na temperatura alternada de 20-30ºC e o substrato pó de coco. As condições mais adequadas para avaliação do desempenho germinativo e vigor das sementes de P. pyramidalis são as temperaturas constantes de 30ºC e o substrato areia e bagaço de cana, de 25°C, combinada com o substrato vermiculita e 20°C, juntamente com areia e papel toalha. As sementes de P. gardneriana comportaram-se como fotoblásticas neutras, em condição de laboratório, na temperatura de 25 ºC. As sementes de P. bracteosa mantidas no substrato umedecido com volume de água de 3,5 vezes o peso do papel mata-borrão e papel toalha secos apresentaram maior vigor; o umedecimento do substrato vermiculita com água a 60, 70 e 80% da capacidade de retenção do substrato podem ser utilizados em testes de germinação e o vigor das sementes de P. bracteosa. Para a produção de mudas de P. bracteosa devem ser utilizados os substratos vermiculita + esterco ou Tropstrato® + esterco em sacos de polietileno, mantidas em ambiente protegido com tela de sombrite de 50%. O recipiente saco de polietileno combinado com o substrato vermiculita + esterco em ambiente protegido com tela de sombrite 30% e substrato Tropstrato® + esterco no ambiente a pleno sol podem ser recomendados para produção de mudas de P. gardneriana. As melhores condições para produção das mudas de P. pyramidalis são o substrato vermiculita + esterco em sacos de polietileno e ambiente protegido com tela de sombrite 70% e o substrato Tropstrato® + esterco em tubete, mantidas em ambiente protegido com tela de sombrite de 50%.Submitted by (lucia.rodrigues@ufrpe.br) on 2016-08-25T13:42:29Z No. of bitstreams: 1 Elane Grazielle Borba de Sousa Ferreira.pdf: 1952659 bytes, checksum: 5c96f87e08074b71384ef1cfb03067ba (MD5)Made available in DSpace on 2016-08-25T13:42:29Z (GMT).

description The present study aimed to generate information about the morphology of fruits, seeds, seedlings, germination phases and categories of normal and abnormal seedlings of P. bracteosa, P. gardnerian and P. pyramidalis; establish the most appropriate procedure for determining the moisture content of the seeds of the studied species; recommend pre-germination treatment to overcome dormancy of seeds of species; establish the optimum conditions of substrate temperature, photoperiod and levels of moistening of paper substrates and vermiculite for use in germination and seed vigor of the species and to evaluate the effects of different substrates, containers and shading levels on the production of seedlings of the species under study. For that were made descriptions and illustrations of the morphological characteristics of fruits, seeds, seedling and germination stages. For determination of water content was measured using the method oven at 105±3°C for 24 hours, with samples of seeds of different weights 5, 10 and 15 g and using different aluminum capsules (6 cm diameter x 5 cm height) and (8 cm diameter x 3 cm height). To break dormancy of seeds, and the control (no treatment), were performed the following treatments: soaking in water for 24 hours, soaking in water at 80ºC until it reaches room temperature; scarification n°. 100 for mass at the opposite the hilum; scarification n°. 100 for mass followed by soaking in water for 24 hours; chemical scarification with concentrated sulfuric acid for 30 seconds, 1, 5 and 10 minutes. The performance germination and vigor were also evaluated by subjecting the seeds at different temperatures and substrates. To review the photoperiod, the seeds of the species P. gardneriana, were subjected to continuous light, continuous dark, photoperiod of 12 hours light and 12 hours of dark and light and photoperiod of 8 hours light and 16 hours of dark, at constant temperature of 25ºC. In testing the germination and vigor, to evaluate the different levels of water for moistening of the substrate, the seeds of P. bracteosa were sown between a sheet of blotting paper and paper towel moistened in the substrates being equivalent to 2,0; 2,5; 3,0 and 3,5 times the weight of dry substrates. The seeds of P. bracteosa also were sown in vermiculite medium, moist equivalent of 50, 60, 70 and 80% of water holding capacity. The seedlings of the species studied were grown in nursery conditions, testing substrates are semi-fine vermiculite + manure; Tropstrato® + manure, coir dust + manure and sugarcane bagasse + manure in different containers: polyethylene bag and cartridge in different shading levels: full sunlight (0%) and ambient shading in the proportions 30%, 50% and 70%. The variables evaluated were: germination (%), first count (%), germination speed index, length of the primary root and shoot and root dry mass and shoot. The results showed that the fruit of P. bracteosa and P. gardneriana are dried, simple, kind and legume seeds of both species are stenospermics, epigeal germination and seedling phanerocotylar. For more accurate determination of moisture content of seeds of the species P. bracteosa capsules are recommended 6 x 4 cm) and 8 x 3 cm using samples of 5 or 15 g of seed; to P. gardneriana containers are the most suitable for 6 x 4 cm and 8 x 3 cm and seed samples 5, 10 and 15 g, except for sample 15 g and the container 6 x 4 cm, while for P. pyramidalis, it is recommended that the weight of the seed sample 15g and container of 6 x 4 cm. The seeds of P. bracteosa and P. pyramidalis not require the use of pre-germination treatments to overcome dormancy and chemical scarification of the seeds of P. gardneriana sulfuric acid for one minute is the most efficient method. The constant temperature of 25°C and vermiculite, and 20°C and the substrate blotting paper, and 10 and 15°C with the substrate paper towel are recommended for testing of germination and vigor of P. bracteosa. The seeds of P. gardneriana showed high germination and vigor when subjected to constant temperatures of 25 and 30ºC and plated on substrates sand and vermiculite, 20°C when kept in sugarcane bagasse and 10°C on the paper towel and the alternating temperature of 20-30ºC and coconut coir substrate. The best conditions for performance evaluation germination and vigor of P. pyramidalis are the constant temperatures of 30ºC and the mixture of sand and sugar cane bagasse, 25°C, combined with vermiculite and 20°C, along with sand and paper towels. The seeds of P. gardneriana behaved as neutral photoblastic in laboratory condition at 25ºC. The seeds of P. bracteosa kept the substrate moistened with water volume of 3,5 times the weight of blotter paper and paper towel dried showed higher vigor. The vermiculite moistened with water at 60, 70 and 80% capacity retention of the substrate can be used in the germination and vigor of P. bracteosa. For the production of seedlings of P. bracteosa should be used vermiculite substrates + manure or Tropstrato® + manure in plastic bags and kept in the greenhouse with shade screen 50%. The plastic bags combined with manure + vermiculite in a greenhouse with 30% shade screen and substrate Tropstrato® + manure in full sun environment can be recommended for seedling production P. gardneriana. The best conditions for production of seedlings of P. pyramidalis are manure + vermiculite in plastic bags and protected environment with 70% shade screen and substrate Tropstrato® + manure in tubes, kept in the greenhouse with shade screen 50%.
