Conservação de recursos fitogenéticos da Amazônia em coleções diversificadas: avaliação do estabelecimento de doze espécies.

O CPAA esta testando um metodo de conservacao fundamentado em aspectos genetico-ecologicos. Em uma area de 0,25ha, procurou-se representar as estrategias utilizadas pelas especies autoctones para manterem-se em equilibrio no ecossistema tropical: diversidade, densidade e variabilidade genetica. A pesquisa, iniciada em janeiro de 1994, estuda a conservacao de recursos geneticos de sete especies frutiferas (Theobroma grandiflorum, T. cacao, Bactris gasipaes, Euterpe spp, Myrciaria dubia, Rollinia mucosa e Couma utilis) e cinco florestais (Hevea spp, Ceiba pentandra, Jacaranda copaia, Buchenavia huber, Trattinickia burserifolia), utilizando-se tres espacamentos. As caracteristicas biometricas das plantas sao anualmente medidas e, apos cinco anos, a viabilidade tecnica sera avaliada quanto a sobrevivencia e capacidade das especies em deixar descendentes. Preliminarmente, as especies que apresentaram valores superiores na avaliacao de estabelecimento foram C. pentandra entre as florestais (medias de 4,76m de altura e 11,46cm de diametro, a 50cm do solo) e R. mucosa entre as fruteiras (media de 3,71m de altura e 6,28cm de diametro, a 50cm do solo).

Condições climáticas, caracteristicas do fruto e sistema de colheita na qualidade fisiológica de sementes de jacarandá

As características dos frutos coletados e o sistema de colheita utilizado dependem da espécie que se está estudando. Esses parâmetros devem ser bem estabelecidos para permitir a obtenção de sementes com máxima germinação e vigor. Com o objetivo de determinar as características dos frutos e o sistema de colheita mais favorável à qualidade fisiológica de sementes de Jacaranda cuspidifolia Mart., por dois anos consecutivos foram colhidos frutos na árvore (verdes fechados, marrons fechados e marrons abertos) e frutos marrons no chão. As sementes foram extraídas, limpas e avaliadas quanto ao teor de água, germinação e vigor (primeira contagem do teste de germinação, comprimento da parte aérea e da radícula das plântulas e porcentagem de emergência). Para a obtenção de sementes de jacarandá com melhor qualidade fisiológica, os frutos devem ser colhidos na árvore marrons, abertos ou fechados e com teor de água inferior a 24,4%.

Floral visitors and reproductive strategies in five melittophilous species of Bignoniaceae in Southeastern Brazil

Com objetivo de avaliar as estratégias de polinização de espécies de Bignoniaceae, foram estudados a biologia floral e os visitantes florais de cinco espécies, três arbustivas do cerrado (Arrabidaea brachypoda (DC.) Bor., Jacaranda decurrens Cham. e Jacaranda oxyphylla Cham.) e duas lianas da orla da floresta estacional semidecidual (Arrabidaea samydoides (Cham.) Sandw. e Arrabidaea triplinervia H. Baill.), na região de Botucatu (22º52'20 S e 48(0)26'37 W), estado de São Paulo, sudeste do Brasil. Os períodos de florescimento, principalmente entre espécies do mesmo habitat, apresentaram sobreposição parcial. Observou-se que as cinco espécies são alogâmicas funcionais, melitófilas, nototríbicas, polinizadas principalmente por abelhas grandes de língua comprida. Algumas abelhas coletoras de pólen de tamanho médio e pequeno atuaram como polinizadoras ocasionais, enquanto outros visitantes foram pilhadores. Cada uma das Bignoniaceae apresentou um conjunto particular de polinizadores havendo apenas duas espécies comuns a mais de uma delas. Não houve partilha de polinizadores mesmo entre bignoniáceas que, no mesmo habitat, apresentaram períodos de florescimento simultâneo.

Spatial patterns or trees in the Picinguara coastal sandy forest (state of Sao-Paulo, Brazil)

The species of the sandy plains forests (forests of the ''restingas'') have not yet had their spatial patterns studied as aids to the understanding of the diversity found in the different physiognomies along the Brazilian coast. In this paper a 10 x 10 m quadrat framework laid in a hectare of a tree dominant forest in the sandy plains of the Picinguaba area of the Serra do Mar State Park (municipality of Ubatuba, state of São Paulo, Brazil) was used to assess the spatial pattern of distribution for the ten most important species : Pera glabrata, Euterpe edulis, Eugenia brasiliensis, Alchornea triplinervea, Guatteria australis, Myrcia racemosa, Jacaranda semiserrata, Guarea macrophylla, Euplassa cantareirae and Nectandra oppositifolia. The spatial patterns were inferred through the calculations of their T-Square Index (C) and Dispersal Distance Index (I). P. glabrata shows a random pattern, E. edulis aggregate, E. brasiliensis, A. triplinervia, G. australis, E. cantareirae and N. oppositifolia with a tendency between aggregate and uniform and, M. racemosa, J. semiserrata and G. macrophylla between aggregate and random. Although the indexes are dependent of the sample size and of the technique adjustments, the relationship of the pattern with the environmental factors is shown by clustering methods. The results give confirmation of how the spatial patterns bring associations between populations and shape of the vegetation physiognomy.

Associação micorízica em espécies arbóreas, atividade microbiana e fertilidade do solo em áreas degradadas de cerrado

The recuperation of areas used during the construction of the hydroelectric plant, especially in 'borrowed areas', is a difficult and long process since all vegetation and the fertile layer of soil were removed. Interventions in these degraded areas could accelerate the revegetation process. The objective of this research was to evaluate the association of arbuscular mycorrhizal fungi (AMF) in tree species, microbial activity (basal respiration) and fertility of 'cerrado' degraded areas. Soil from two areas, pasture soil and exposed subsoil, were utilized. Organic and mineral fertilization, and liming, were added to the pit for better seedlings' initial growth, where 50 mL of preserved cerrado soil was applied as inoculum of microorganisms. Seedlings of 11 tree species were planted: Anadenanthera falcata (Benth.) Speg ('angico-preto'), Acacia polyphylla D. C. ('monjoleiro'), Stryphnodendron adstringens (Mart.) Coville ('barbatimao'), Dimorphandra mollis Benth ('faveiro'), Hymenaea stigonocarpa Mart. ex Hayne ('jatoba-de-cerrado'), Dipteryx alata Vog. ('baru'), Machaerium acutifolium Vogel ('jacaranda-do-campo'), Schinus terebinthifolia Raddi ('aroeirapimenteira'), Magonia pubescens St. Hil. ('tingui'), Lafoensia pacari St. Hil. ('dedaleira') and Tabebuia aurea (Manso) Benth. & Hook ('ipe-amarelo'). Twelve months later, root samples were colleted at the depth of 0-0.10 m and used for evaluations. The subsoil, as compared to pasture soil, was poor in organic matter and presented less microbial activity. The highest mycorrhizal colonization was seen in the species Acacia polyphylla D. C. (monjoleiro), Magonia pubescens St. Hil. (tingui), Hymenaea stigonocarpa Mart. ex Hayne (jatoba-de-cerrado) and Schinus terebinthifolia Raddi (aroeira-pimenteira). These species could be indicated in revegetation projects in 'cerrado' degraded areas. Plants from both areas showed seedlings form high mycorrhizal colonization and low numbers of spores.

Potencial da espectroscopia no infravermelho próximo para distinção de carvão de madeira de Eucalyptus e nativa

The objective of this study was to evaluate the potential of near infrared spectroscopy (NIRS) associated with multivariate statistics to distinguish coal produced from wood of planted and native forests. Timber forest species from the C errado (Cedrela sp., Aspidosperma sp., Jacaranda sp. and unknown species) and Eucalyptus clones from forestry companies (Vallourec and Cenibra) were carbonized in the final temperatures of 300, 500 and 700°C. In each heat treatment were carbonized 15 specimens of each vegetal material totaling 270 samples (3 treatments x 15 reps x 6 materials) produced in 18 carbonization (3 treatments x 6 materials). The acquisition of the spectra of coals in the near infrared using a spectrometer was performed. Principal Component Analysis (PCA) and Partial Least Squares Regression (PLS-R) were carried out in the spectra. NIR Spectroscopy associated with PCA was not able to differentiate charcoals produced from native and planted woods when utilizing all carbonized samples at different temperatures in the same analysis; The PCA of all charcoals was able to distinguish the samples depending on temperature in which they were carbonized. However, the separation of native and planted charcoal was possible when the samples were analyzed separately by final temperature. The prediction of native or planted classes by PLS-R presented better performance for samples carbonized at 300°C followed by those at 500°C, 700°C and for all together.

Vicentina Aranha de sanatório a parque: histórias e mudanças

This assignment intents to analyze the recover and the research of the cultural legacy identity of Vicentina Aranha Sanatorium to the inhabitants of the city of São José dos Campos-SP. That initiative becomes present through the importancy of the sanatorium to the public health of Vale do Paraíba in the decades between 30 and 70, of the 20th century. Nowadays this place refuges a park, presenting a reexamination of its space, with the possibility of the leisure practice, entertaining and tourism. The Vicentina Aranha Sanatorium Park presents itself conserving a landscape that is able of being inserted in a continuum past-present resignifying ways of appropriation and use. The word patrimony has many meanings and it‟s commonly associated to the set of goods that someone, the society or an entity owns. Transporting in a determinate territory, the patrimony starts to be a set of goods that are in its limits of administrative competency. (BARRETO, 2000). More than this, the cultural-historical patrimony guard a relation of belonging between it and the entity that has it. The Vicentina Aranha Sanatorium was inaugurated in 1924, with the project of the architect, Ramos de Azevedo, constituting an architectural ensemble placed under governmental trust as a historical and cultural patrimony of the state in 2001. It has a grove with centenary vegetal species like: MOGNO, PEROBA ROSA, JEQUITIBÁ and JACARANDA, constituting also a natural patrimony important for the city. There are projects like “Leitura no Bosque” and it‟s visited by the local population. Today the city seeks a new identity for that place transforming it in the center of industrial and technologic study

Regeneração natural do componente arbóreo após a mortalidade de um maciço de taquara em um fragmento de floresta ombrófila mista em Lages - SC

The present study aimed to analyze the floristic and structural descriptors of tree species natural regeneration in a forest sector with synchronized bamboo (Merostachys multiramea Hackel) die-off (CT) and an adjacent area with continuous canopy cover (ST) in an araucaria forest fragment in the municipality of Lages, Santa Catarina state. A total of 14, 5x5m, plots (six plots in CT sector and eight in ST sector) were allocated, where all tree species regenerative individual with circumference at breast height smaller than 15cm and height higher than 25cm was measured (diameter at soil level) and identified. The richest families were: Myrtaceae (nine), Solanaceae (six) and Aquifoliaceae (four). The Shannon Diversity Index in ST and CT sectors were respectively 2.73 and 2.31. The species with the highest importance values in CT sector were Solanum variabile, Piptocarpha angustifolia, Mimosa scabrella, Jacaranda puberula and Solanum pseudoquina. In ST sector, the species with highest importance values were Myrsine lorentziana, Casearia decandra, Cinnamodendron dinisii, Drimys brasiliensis and Ilex paraguariensis. The results showed that the synchronized bamboo die-off influenced the spatial variation in the floristic and structural descriptors of the tree species natural regeneration.
