Resumo: The removal vegetation coverage stands out as one of the most serious environmental problems in different parts of the world, and in Brazil this is no exception. The Sideroxylon obtusifolium (Roem. & Schult.) T.D.Penn., belongs to the Sapotaceae Juss. Family, is an important species that is currently threatened in the Caatinga biome, which despite that fact, there is lack of studies focused in this species, especially regarding the phenology, natural regeneration and seedling production. Therefore, the objective of this study was to evaluate the different phenological stages, the soil seed bank, the influence of different substrates and shade levels on the production of S. obtusifolium seedlings. Four experiments were carried out: I - phenology: carried out in the rural area of Boa Vista - PB, with 26 individuals of the species, evaluated every 15 days for 30 months. phenological stages of budding, flowering, fruitification and senescence of the species were correlated with the climatic data of the municipality (rainfall, temperature and relative humidity); II - seed bank: carried out with two soil samples collected from the same area where the phenological evaluations were carried out, evaluating the floristic composition, density (relative and absolute), diversity of Shannon- Weaver (H ') and Pielou equability (e'); III - production of S. obtusifolium seedlings in different substrates: carried out in a protected environment of the Departamento de Fitotecnia e Ciências Ambientais do Centro de Ciências Agrárias da Universidade Federal da Paraíba (DFCA-CCA/UFPB), where were evaluated 13 substrates formulated from washed sand, bovine manure, subsoil, kaolin waste and Basaplant® (commercial substrate); IV - growth of S. obtusifolium seedlings at different levels of shade: at the forest nursery of the Laboratório de Ecologia Vegetal (CCA-UFPB), using the following shading levels: 0, 30, 50 and 70% shade. The variables evaluated in the production of seedlings were: height, stem diameter, height/stem diameter ratio, absolute height growth rate, absolute diameter growth rate, number of branches, root length, height/ root length ratio, shoot dry matter (stem, branches, leaves), root dry matter, total dry matter, shoot and root dry matter ratio (stem, branches, leaves), Dickson quality index and percentage of leaves and roots. There was no significant effect between the phenological characteristics evaluated and the environmental variables (temperature, humidity), with a strong oscillation in intensity and in the activity index. During ix the evaluation periods, senescence occurred in all individuals of S. obtusifolium. The peak of the intensity of the phenological stages of budding, floral bud, flowering and fruitification was less than 60%. In the seed bank of the studied area, 58 species were identified, distributed in 49 genera and 23 families, with predominance of herbaceous species, and belonging to the Fabaceae family. The S. obtusifolium species was not found in any of the soil samples. For the production of seedlings, kaolin waste and bovine manure are indicated, while pure subsoil associated with washed sand is not recommended. The production of seedlings of the species can be carried out under full sun or with up to 15% of shading, without significant losses in the seedlings vigor.

A Sideroxylon obtusifolium (Roem. & Schult.) T.D.Penn., pertencente à família Sapotaceae Juss. é uma importante espécie que se encontra ameaçada no bioma Caatinga, mesmo assim há carências de estudos voltados para a mesma, sobretudo com relação à fenologia, regeneração natural e produção de mudas. Nesse sentido, objetivou-se avaliar as diferentes fenofases, o banco de sementes do solo, a influência de diferentes substratos e os níveis de sombreamento na produção de mudas de S. obtusifolium. Para tanto, foram realizados quatro experimentos, a seguir relacionados: I - fenologia: conduzido na zona rural do município de Boa Vista - PB com 26 indivíduos da espécie, avaliados a cada quinze dias durante 30 meses. As fenofases de brotamento, floração, frutificação e senescência da espécie foram correlacionadas com os dados climáticos do município (precipitação pluvial, temperatura e umidade relativa do ar); II - banco de sementes: realizado com duas coletas de solo provenientes da mesma área onde foi realizada as avaliações fenológicas, procedendo-se com a avaliação da composição florística, densidades (relativa e absoluta), diversidade de Shannon-Weaver (H´) e equabilidade de Pielou (e´); III - produção de mudas de S. obtusifolium em diferentes substratos: realizado em ambiente protegido do Departamento de Fitotecnia e Ciências Ambientais do Centro de Ciências Agrárias da Universidade Federal da Paraíba (DFCA-CCA/UFPB), onde foram avaliados 13 substratos formulados a partir de areia lavada, esterco bovino, terra de subsolo, rejeito de caulim e Basaplant® (substrato comercial); IV - crescimento de mudas de S. obtusifolium em diferentes níveis de sombreamento: realizado no viveiro florestal do Laboratório de Ecologia Vegetal (CCA-UFPB), sendo considerados os seguintes níveis de sombreamento: 0, 30, 50 e 70% de sombra. As variáveis avaliadas nos trabalhos de produção de mudas foram: altura, diâmetro do colo, relação altura/diâmetro do colo, taxa de crescimento absoluto de altura, taxa de crescimento absoluto de diâmetro, número de ramos, comprimento da raiz, relação altura/comprimento da raiz, massa seca da parte aérea (caule, ramos e folhas) e da raiz, massa seca total, relação entre a massa seca da parte aérea e de raízes, índice de qualidade de Dickson e porcentagem de folhas e raízes. Não houve efeito vii significativo entre as características fenológicas avaliadas e as variáveis ambientais (temperatura, umidade), com forte oscilação na intensidade e no índice de atividade. Durante os períodos de avaliação ocorreu senescência em todos os indivíduos de S. obtusifolium. O pico da intensidade das fenofases brotamento, botão floral, floração e frutificação foi inferior a 60%. No banco de sementes da área estudada foram reconhecidas 58 espécies, distribuídas em 49 gêneros e 23 famílias, com predominância de espécies herbáceas, assim como pertencentes à família Fabaceae. A espécie S. obtusifolium não foi constatada em nenhuma das coletas de solo. Para a produção de mudas, o rejeito de caulim e o esterco bovino são indicados, enquanto que a terra de subsolo pura e associada apenas com areia lavada não é adequada. A produção de mudas da espécie pode ser realizada em pleno sol ou com até 15% de sombreamento, sem perdas significativas no seu vigor.Universidade Federal da ParaíbaBrasilCiências Fitotecnia e Ciências AmbientaisPrograma de Pós-Graduação em AgronomiaUFPBAlves, Edna Ursulinohttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4794120D6Araújo, Lenyneves Duarte Alvino dehttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4710251Y2Cruz, Flávio Ricardo da Silva2019-05-24T10:39:32Z2019-05-142019-05-24T10:39:32Z2018-02-26info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesishttps://repositorio.ufpb.br/jspui/handle/123456789/14391porAttribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/info:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações da UFPBinstname:Universidade Federal da Paraíba (UFPB)instacron:UFPB2019-05-25T06:06:50Zoai:repositorio.ufpb.br:123456789/14391Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufpb.br/PUBhttp://tede.biblioteca.ufpb.br:8080/oai/requestdiretoria@ufpb.br|| diretoria@ufpb.bropendoar:2019-05-25T06:06:50Biblioteca Digital de Teses e Dissertações da UFPB - Universidade Federal da Paraíba (UFPB)false
