Yerba mate (Ilex paraguariensis) is a forest species consumed in the form of non-alcoholic beverages South America, with applications foods, cosmetics, and pharmaceutical industries. The leaves are globally recognized for their important bioactive compounds, including, saponins. We adjusted vanillin-acid sulfuric method determining spectrophotometrically total saponin yerba leaves. Seeking to maximize extraction saponins from leaves, Doehlert design combined Response Surface Methodology...
Abstract: The objective of this work was to evaluate the feasibility early selection open-pollinated yerba mate (Ilex paraguariensis) progenies, and classify best parents candidates for clones. germplasm is composed 140 progenies collected from areas within natural distribution species in Southern Brazil a commercial genotype (control). experiment established Ivaí, state Paraná, Brazil, March 1997, randomized complete blocks, with ten replicates, linear plots six plants. mass (kg per plant)...
We examined the correspondence in performance between trees selected from a family test and their respective clones clonal of Eucalyptus.Full-sib families were obtained controlled pollination among individuals Eucalyptus grandis E. urophylla.The hybridizations did not follow factorial scheme.The tests carried out at three locations Eunápolis Itabela counties, Bahia, Brazil, 2003.Four hundred ninety-seven high-performance selected, by individual BLUP procedure, two years age, based on wood...
O conhecimento e o entendimento da estruturação genética intrapopulacional são importantes para manejo conservação dos recursos genéticos florestais, bem como avaliar os impactos exploração fragmentação estabelecer estratégias de amostragem em populações naturais. objetivo deste estudo foi determinar a estrutura espacial (EGE) dentro das Dimorphandra mollis Benth., visando gerar informações in situ naturais espécie. Dez locos aloenzimáticos foram utilizados estimar as frequências 20 alelos...
ABSTRACT Commercial biomass production is one of the main indicators for selecting erva-mate (Ilex paraguariensis) progenies and clones. Traditional techniques to obtain such information depend on harvesting trees there are some limitations involved, as high cost reduced convenience. Thus, in our research we evaluated efficiency indirect methods through commercial estimation score productivity according different provenances, gender morphotypes. In a provenances trial installed 1997, two...
The objective of this work was to evaluate eucalypt commercial clones in Ponta Porã region, located Mato Grosso do Sul State, Brazil. Two clonal tests were established 2009. Each field trial consisted five (AEC 144, AEC 224, GG 100, 58 and 1277) three seed checks (Eucalyptus grandis, Eucalyptus urophylla the hybrid x grandis). experiments designed as randomized blocks, with four replicates square plots containing 25 (trial 1) 16 plants 2), at spacing 3 m m. At age 51 months, circumference...
Dimorphandra mollis é uma espécie nativa do Cerrado com grande potencial econômico e tem sido alvo de intensa exploração, principalmente seus frutos por causa princípio ativo composto rutina, importante para a produção fármacos. Algumas propostas têm surgido coleta controlada desses frutos, forma minimizar perda diversidade genética, entretanto existem poucas informações sobre aspectos ecológicos genéticos da espécie. Nesse sentido, realizou-se o estudo estrutura genética meio marcadores...
Eucalyptus plantations in Brazil are expanding toward the northern and mid-western regions of country. The objective present study was to select clones adapted local conditions, with a focus on Cerrado region. Three clonal experiments were conducted municipalities Catalão, Corumbá-de-Goiás, Luziânia, Goiás State, 109 genotypes eucalypts. experimental design consisted randomized complete block single-tree plots 29 blocks. Diameter at breast height total all trees measured four years after...
http://dx.doi.org/10.5902/1980509818465Este trabalho foi realizado com objetivo de: i) comparar o índice de seleção somatório Z das variáveis padronizadas em relação ao clássico (SMITH, 1936; HAZEL, 1943) e soma postos (MULAMBA MOCK, 1978), por meio caracteres crescimento tecnológicos da madeira ii) verificar a interação progênies x ambientes na simultânea vários caracteres, base no padronizadas. Para isto, utilizado um teste irmãos completos Eucalyptus urophylla grandis avaliado dois...
As áreas de ocorrência florestas paludosas se encontram alteradas e restritas devido aos processos destruição fragmentação, com consequente redução do seu tamanho populacional. Calophyllum brasiliense Camb. é uma espécie arbórea abundante em ambientes ciliares, à sua preferência colonizar solos alta saturação hídrica, sendo considerada especialista hábitat. Além das consequências ecológicas, como mortalidade baixo recrutamento, poderá ocorrer perda da variabilidade genética, comprometendo a...
The objective of this study was to assess the genetic variability in two natural populations Calophyllum brasiliense located along different rivers state Minas Gerais, Brazil, using RAPD molecular markers. Eighty-two polymorphic fragments were amplified 27 primers. values obtained for Shannon index (<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M1"><mml:mrow><mml:mi>I</mml:mi></mml:mrow></mml:math>) 0.513 and 0.530 on margins Rio Grande das Mortes, respectively, demonstrating...
O objetivo deste trabalho foi avaliar a eficiência do índice Z (índice somatório das variáveis padronizadas) na seleção de progênies irmãos completos entre Eucalyptus grandis e urophylla via método dos quadrados mínimos (MQM) da melhor predição linear não viesada (Blup). Os experimentos foram realizados em dois tipos solo ambiente, blocos ao acaso com cinco repetições, oito plantas por parcela espaçamento 3x2 m. Aos três anos idade, as avaliadas quanto incremento médio anual madeira, à...
Progenies de irmaos germanos foram avaliadas com o objetivo comparar desempenho arvores selecionadas em testes progenies seus respectivos clones nos teste clonais. Os experimentos implantados em blocos completos casualizados cinco repeticoes e plantas por parcela, no espacamento 3 x m quatro testemunhas. O volume de madeira cada arvore foi avaliado segundo anos. As 173 avaliadas em testes clonais dois diferentes locais. mesmo delineamento experimental utilizado, porem 20 parcelas de uma...
Sustainability on farms is a challenge to competitiveness in the globalized market.In this scenario, due strong environmental, economic and social appeal, crop-livestock-forest integration systems have been considered as future of agriculture.Regarding approach, system based diversification income generating activities, with revenue entry at different times, rationalization resource use reduction risk financial losses.Thus, purpose work was carry out analysis system, located Boa Vereda's...
Eucalypts are a long-cycle crop that have been introduced in Brazil during several decades.The germplasm banks of the country make available populations whose botanical classifications somewhat outdated since these subject to modifications over years.This study outlines review species with Anhembi Experimental Station Forest Sciences (ESALQ/USP), one Brazil's main eucalypt and discusses possible implications for breeding programs use said germplasm.In this survey, we found records indicate...

An especially important species in South America, yerba mate (Ilex paraguariensis A.St.-Hil) is traditionally consumed as tea, chimarrão and tererê. Due to the formation of plantations with low productivity high heterogeneity, genetic improvement actions have been conducted a way generate more productive cultivars this species. In sense, present study aimed estimate phenotypic parameters production traits earlier provenance progeny tests, implanted municipalities Chapecó Guatambu, western...
Bamboo plantation has gained great attention in Brazil due to its useful production provided the society and ecological, economic, social cultural functions of these plantations. For establishment high productivity plantations, evaluation germplasm selection superior genotypes is necessary. This work aimed at early genetic parameters potential bamboo species for planting Brasília/DF. this purpose, a clonal test consisting seven was established: Bambusa oldhamii, vulgaris, vulgaris var....
