Download or read book Germinação de sementes e morfologia de frutos, sementes, plântulas e plantas jovens de algumas espécies do cerrado written by N. G. Urquiza and published by . This book was released on 2004 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: O bioma do cerrado vem sofrendo intensas alterações e necessita de conhecimento sobre germinação e morfologia das espécies nativas para a sua recuperação. O objetivo deste trabalho foi obter informações sobre germinação, armazenamento e morfologia de frutos, sementes e plantulas e plantas jovens de algumas espécies nativas para subsidiar programas de produção de mudas e recuperação de áreas. As coletas de frutos e sementes de Anadenanthera falcata Myracrodruon urundeuva, Astronium fraxinifonium, Matayba guianensis, Styrax ferrugineus e Gomidesia lindeniana foram realizadas em Planaltina - DF; Vão do Paranã, Formosa - GO; e em Paracatu - MG. posteriormente os frutos foram para o laboratório de biologia vegetal da embrapa cerrados, e após um período correspondente a 3 dias, as sementes foram divididas em dois lotes e colocadas sob dois tipos de armazenamento: em temperatura ambiente 25C (+_ 0,5) e 60% (+_3%) de U.R, e Câmara fria à 7C (+_1%) e 80% (+_5%) de U.R . Os testes de germinação foram realizados em germinadores a 25C utilizadas 250 sementes por espécie, em placas de petri. Foram feitos testes em laboratórios com sementes recém - coletadas e posteriormente a cada 30 dias de armazenamento. As sementes que não germinaram foram submetidas ao teste de tretazolio (1%), sendo que os valores e colorações observados não são condizentes com sementes viáveis de acordo com as regras brasileiras de sementes. As sementes de A. falcata e de M. urundeuva, armazenadas sob temperatura ambiente por três meses, apresentaram respectivamente germinação de 95% e 75%. Já sementes de A fraxinifolium, armazenadas sob as mesmas condições apresentaram 100% de germinação ao final de 4 meses de armazenamento. Sementes de S.ferrugineus, depois de armazenadas por dois meses em condição ambiental apresentaram somente 20% de germinação. As sementes das espécies A. falcata e M. urundeuva que foram armazenadas por um ano sob a condição câmara fria apresentaram 95 % e 70 % de germinação respectivamente. As sementes de A. fraxinifolium, armazenadas sob as mesmas condições por três meses, alcançaram 90% de germinação, enquanto germinação de sementes de S. ferrugineus alcançou 25% com dois meses de armazenamento na mesma condição. Para M. guianensis os resultados observados para sementes recém - coletadas ficam em 60 % . O tratamento Câmara fria apresentou boas taxas de germinação para A. falcata, e M. urundeuva. ao contrario do observado para A. fraxinifolium que apresentou melhores resultados sob armazenamento ambiente. para caracterização morfológica foram tomados como base 50 indivíduos para as observações e para obtenção de pesos e medidas. A germinação foi epigea para as espécies A. falcata S. ferrugineus, com abscisão dos cotilédones aos 25 e 90 dias respectivamente, e hipogenea para A. fraxinifolium. A transição do desenvolvimento plantula para planta jovem foi mais rápida para as espécies A. falcata, A fraxinifolium e M. guianensis o que indica breve estabelecimento e satisfatória produção de mudas.

Download or read book Epoca de dispersao e fisiologica de sementes do cerrado written by M. M. V. da S. WETZEL and published by . This book was released on 1997 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: O conhecimento da biologia das sementes e essencial para a compreensao do funcionamento de uma comunidade. Este estudo teve por objetivo testar as seguintes hipoteses: 1) que as sementes das especies do estratoarbustivo-arboreo do cerrado lato sensu (fisionomias campo sujo, cerrado stricto sensu, cerradao e mata mesofitica) que nao resistem a dessecacao sao dispersas no periodo de chuvas e as sementes que resistem a dessecacao podem ser dispersas em qualquer epoca do ano; 2) que as sementes das especies de estrato arbustivo-arboreo do cerrado lato sensu dispersas no fim da estacao chuvosa possuem mecanismos de dormencia; 3) que as sementes das especies da mata de galeria, pela sua condicao ecologica, apresentam comportamento semelhante as de florestas tropicais umidas. Neste estudo foram coletadas 516 acessos de sementes de 1994 a 1997, nas diversas latitudes e longitudes do cerrado, abrangendo 143 especies de 46 familias botanicas. Cada amostra foi separada em dois lotes. Para as sementes do primeiro lote foram determinados o peso, o conteudo de umidade e a viabilidade (teste de tetrazolio), seguido do poder germinativo (teste de germinacao em condicoes basicas, a 25oC no escuro em papel de filtro) e da germinacao estimulada ou superacao da dormencia (escarificacao mecanica, luz, temperatura alternada de 20/30oC em vermiculita). O segundo lote de sementes foi para uma camara de secagem a 15% de umidade relativa e 20oC por 30 dias. Apos este periodo, a umidade das sementes foi determinada e, a seguir, as mesmas foram submetidas aos testes descritos para o primeiro lote. O mes de setembro apresentou o maior numero de especies dispersando sementes, em todas as fitofisionomias. Foram encontradas sete especies com insucesso reprodutivo. As sementes que nao resistem a dessecacao (17% das especies do cerrado lato sensu e 6% das especies de mata de galeria) sao dispersas nos meses de novembro a fevereiro enquanto as sementes que resistem a dessecacao sao dispersas ao longo do ano. Das sementes das especies do Cerrado stricto sensu estudadas, 53% possuem algum tipo de dormencia e sao dispersas ao longo do ano, porem todas as sementes dispersas em fevereiro, marco e abril possuem algum grau de dormencia. Das especies estudadas da mata de galeria encontrou-se 52% com sementes dormentes. Algumas especies com sementes dormentes apresentaram uma variacao de intensidade de dormencia, entre diferentes amostras da mesma especie. A impermeabilidade de tegumento e o tipo de dormencia que aparentemente predomina no cerrado lato sensu. As sementes das especies da mata de galeria estudadas apresentaram uma media de peso das sementes menor que do cerrado lato sensu (media 0,4512g para as de mata e 0,5561g para o cerrado) menores conteudos de umidade inicial e final do que as sementes das especies do cerrado. Assim verificou-se que, de acordo com as duas primeiras hipoteses, as sementes que nao resistem a dessecacao sao dispersas na primeira metade da epoca chuvosa e todas as sementes dispersas na segunda metade da estacao chuvosa tem dormencia. Por outro lado, uma baixa porcentagem das sementes de mata de galeria nao resistem a dessecacao, ao contrario das sementes de florestas tropical umida.

Download or read book Tropical Biology and Conservation Management - Volume X written by Kleber Del Claro and published by EOLSS Publications. This book was released on 2009-05-11 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Encyclopedia of Tropical Biology and Conservation Management is a component of the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Tropical environments cover the most part of still preserved natural areas of the Earth. The greatest biodiversity, as in terms of animals and plants, as microorganisms, is placed in these hot and rainy ecosystems spread up and below the Equator line. Additionally, the most part of food products, with vegetal or animal origin, that sustain nowadays human beings is direct or undirected dependent of tropical productivity. Biodiversity should be looked at and evaluated not only in terms of numbers of species, but also in terms of the diversity of interactions among distinct organisms that it maintains. In this sense, the complexity of web structure in tropical systems is a promise of future to nature preservation on Earth. In the chemicals of tropical plant and animals, could be the cure to infinite number of diseases, new food sources, and who knows what more. Despite these facts tropical areas have been exploited in an irresponsible way for more than 500 years due the lack of an ecological conscience of men. Exactly in the same way we did with temperate areas and also tropical areas in the north of Equator line. Nowadays, is estimated that due human exploitation, nation conflicts and social problems, less than 8% of tropical nature inside continental areas is still now untouchable. The extension of damage in the tropical areas of oceans is unknown. Thus so, all knowledge we could accumulate about tropical systems will help us, as in the preservations of these important and threatened ecosystems as in a future recuperation, when it was possible. Only knowing the past and developing culture, mainly that directed to peace, to a better relationship among nations and responsible use and preservation of natural resources, human beings will have a long future on Earth. These volumes, Tropical Biology and Natural Resources was divided in sessions to provide the reader the better comprehension possible of issue and also to enable future complementation and improvements in the encyclopedia. Like we work with life, we intended to transform this encyclopedia also in a “life” volume, in what new information could be added in any time. As president of the encyclopedia and main editor I opened the theme with an article titled: “Tropical Biology and Natural resources: Historical Pathways and Perspectives”, providing the reader an initial view of the origins of human knowledge about the tropical life, and what we hope to the future. In the sequence we have more than 100 chapters distributed in tem sessions: Tropical Ecology (TE); Tropical Botany (TB); Tropical Zoology (TZ); Savannah Ecosystems (SE); Desert Ecosystems (DE); Tropical Agriculture (TA); Natural History of Tropical Plants (NH); Human Impact on Tropical Ecosystems (HI); Tropical Phytopathology and Entomology (TPE); Case Studies (CS). This 11-volume set contains several chapters, each of size 5000-30000 words, with perspectives, applications and extensive illustrations. It is the only publication of its kind carrying state-of-the-art knowledge in the fields of Tropical Biology and Conservation Management and is aimed, by virtue of the several applications, at the following five major target audiences: University and College Students, Educators, Professional Practitioners, Research Personnel and Policy Analysts, Managers, and Decision Makers and NGOs.
