“…O CF do dendezeiro adulto varia entre 700 e 800 cm (Kee et al, 2003), aumentando significativamente em função da idade até 10 ou 13 anos (Aholoukpè et al, 2013) Resende (2007), indicando baixa probabilidade de ganhos (Tabela 2). Yuan & Weng (1993) não observaram diferença genética ao comparar AP de oito cruzamentos HIE OxG, concluindo não ser possível obter ganhos expressivos com seleção.…”

PALAVRAS-CHAVE Elaeis guineenses Elaeis oleífera Palma de óleo REML/BLUP KEYWORDS Elaeis guineenses Elaeis oleíferaOil palm REML/BLUP RESUMO: Híbridos interespecífi cos entre o caiaué e o dendezeiro (HIE OxG) são resistentes ao amarelecimento fatal (AF), principal problema fi tossanitário da dendeicultura. Embora já existam cultivares de HIE OxG recomendadas para o plantio, o melhoramento genético desse tipo de material ainda está em fase inicial, de modo que existe a possibilidade de altos ganhos com seleção. Neste estudo, foram avaliadas características vegetativas na fase juvenil de 42 progênies de HIE OxG em área de incidência do AF. As progênies foram obtidas a partir de cruzamentos de genitores de caiaué das origens Manicoré, Manicoré x São Bartolomeu e Coari e dendezeiro do tipo pisífera da origem La Mé. Três experimentos com 16 progênies, sendo três comuns aos três experimentos, foram estabelecidos no delineamento blocos casualizados com quatro repetições e 12 plantas por parcela. As avaliações foram realizadas dos 42 aos 79 meses de idade, com periodicidade de 6 a 16 meses. Para todas as características, foi observada baixa variabilidade genética, com valores de coefi ciente de variação genético entre 1,5 e 5,2%. As herdabilidades foram baixas (0,03 a 0,199), com exceção da emissão foliar que foi moderada (0,215). A seleção das cinco melhores progênies, segundo RML/BLUP, promoveria redução de 7,4% na altura da planta, 4,5% no comprimento da ráquis, 5,6% no comprimento da folha, 4,9% no comprimento do folíolo, 5,6% no número de folíolos e ganho de 7,1% na emissão foliar. Os resultados indicam baixa expectativa de ganhos com seleção para características vegetativas nas progênies estudadas. ABSCTRACT: Interspecifi c hybrids between caiaué and oil palm (HIE

“…Most of the total carbon in plantations is stored in aboveground biomass (trunk, branches, foliage) [8,9]. Many researchers have focused only on carbon sequestration by the tree [8,[10][11][12]; less is known about the carbon pool in understory vegetation.…”

Patterns of carbon (C) allocation across different stages of stand development in Eucalyptus urophylla × E. grandis plantations are not well understood. In this study, we examined biomass and mineral soil C content in five development stages (1, 2, 3, 4-5, and 6-8 years old) of a Eucalyptus stand in southern China. The tree biomass C pool increased with stand age and showed a high annual rate of accumulation. Stems accounted for the highest proportion of biomass C sequestered. The C pool in mineral soil increased initially after afforestation and then declined gradually, with C density decreasing with soil depth. The upper 50 cm of soil contained the majority (57%-68%) of sequestered C. The other biomass components (shrubs, herbaceous plants, litter, and fine roots) accounted for <5% of the total ecosystem C pool. Total C pools in the Eucalyptus plantation ecosystem were 112.9, 172.5, 203.8, 161.1, in the five developmental stages, respectively, with most of the C sequestered below ground. We conclude that Eucalyptus plantations have considerable biomass C sequestration potential during stand development. OPEN ACCESSForests 2015, 6 1764

“…High yield and low production costs of palm oil are the reasons driving commercial plantation companies to cultivate oil palm trees on a large scale [2]. Since the 1990s, palm plantations are in expansion in humid tropical areas, and land under oil palms increased to 12.6 million hectares in 2010 with annual palm oil production exceeding 32 million tons suggests that global demand for palm oil will be about 62-63 million tons in 2015 [3]. In the case of Malaysia, first oil palm plantations established in 1917, the oil palm area has expanded continuously, and recent increases in the demand for food, chemicals and biofuels have led to a surge in land conversion rates [4,5,6,7].…”
