Aniba rosaeodora is an Amazonian tree species that belongs to the family Lauraceae. Due intense exploitation for extraction of essential oils (mainly linalol), A. now considered endangered species. On other hand, there little information about its ecophysiology which would be useful support future forest planting programs. Hence, effect different light intensities on growth and photosynthetic characteristics young plants was studied. Nine-month-old were subjected four treatments (T1= 10 a...

Copaiba oils are important medicinal products used primarily for their healing and anti-inflammatory activities. Consisting of sesquiterpenes diterpenes, these have variable composition which, according to the literature, may originate from several factors. In order analyze relationship between chemical abiotic factors such as seasonality, diameter at breast height (DBH) soil composition, sixteen oilresin samples Copaifera multijuga Hayne, Ducke Forest Reserve (Manaus City, Amazon State,...

Oils of various species Copaifera are commonly found in pharmacies and on popular markets widely sold for their medicinal properties. However, the chemical variability between within lack standardization these oils have presented barriers to wider commercialization. With aim recognize patterns composition copaiba oils, 22 oil samples C. multijuga Hayne were collected, esterified with CH2 N2 , characterized by GC-FID GC/MS analyses. The chromatographic data processed using hierarchical...

The Amazonian tree Aniba rosaeodora Ducke, which provides a valued essential oil for perfume industry, is at risk of extinction. An alternative source this product would be the obtained by steam distillation leaves same plant—which does not involve sacrifice tree. However, there still technical criterion to ensure that determined result sustainable production process. One step towards defining know differences in compositions trees different stages growth establish age from can commercially...

The Amazonian tree Aniba rosaeodora Ducke, whose wood provides commercial essential oil for perfumery houses, is at risk of extinction and listed by CITES. An alternative source this would be to trim leaves young plants steam distill them obtain the oil. Four-year-old plant material could provide an that can both economical eventually a replacement in perfumery. A characterization from these has been obtained comprehensive two-dimensional gas chromatography. analytical technique was able...

Comumente, o óleo de andiroba é extraído na Amazônia pelo método tradicional ou ainda por prensa. A eficiência extração está relacionada ao aquecimento e teor água das sementes. Desta forma, a determinação um modelo secagem que represente satisfatoriamente os dados experimentais suma importância para minimizar as alterações promovidas processo obtendo-se, consequentemente, produto qualidade. O objetivo do trabalho foi descrever cinética sementes andiroba, tal como ajustar modelos matemáticos...

Leaves from the morphologically similar <italic>Aniba rosaeodora</italic> and parviflora</italic> were used to obtain ESI V_L-EASI-MS fingerprinting spectra. The method differentiated rapidly unequivocally two species.

Internal retranslocation is an important mechanism for nutrient conservation in plants, which depends on different factors. However, there are little data about this subject, especially tropical forest species. This study aimed to evaluate the macronutrient dynamic and influence of ecological (P: pioneer x NP: non-pioneer) phenological (ND: non-deciduous D: semideciduous / deciduous) characteristics content leaves five tree species monospecific plantations Brazilian Amazon: Acacia mangium...

Este trabalho, teve como objetivo estudar a germinação das sementes de pau-de-balsa (Ochroma lagopus Sw., Bombacaceae) em diferentes estágios maturação aparente dos frutos; provenientes árvores com diâmetros altura do peito (DAP) e tratadas para quebra dormência. No primeiro experimento, avaliou-se frutos verdes, verdosos (verde amarelado), negros (fruto fechado) deiscentes aberto painas expostas). segundo, da mesma idade DAP's: pequeno (5,4 cm), médio (9,1 cm) grande (13,2 cm). terceiro,...

O objetivo deste trabalho foi estabelecer um protocolo para a regeneração in vitro de pau-rosa (Aniba rosaeodora Ducke), utilizando brotações apicais e segmentos nodais inoculados em meio cultura com distintas concentrações diferentes reguladores crescimento. Explantes esterilizados soluções benomyl (4,0 g.L-1) por 24 horas hipoclorito sódio 20% + tween 20 minutos, foram submetidos experimento indução broto, raiz calo MS1 acrescido 30g.L-1 sacarose 9g.L-1 agar, suplementado BAP (0,0 4,0...

Aniba canelilla (H.B.K.) Mez. is a tree species from Amazon that produces essential oil. The oil extraction its leaves and stems can be an alternative way to avoid the cutting for production of aim this study was analyse factors may influence biomass resprouts after pruning A. trees. crowns were pruned in wet season nine months remaining crown collected, dry season. results showed yield chemical composition differed among stems, resprouts. stems' between seasons had higher resprouting than...

Este trabalho teve por objetivo estudar a variabilidade genética meio de testes progênies e determinar o ganho genético seleção individual, combinada índice multiefeito, em Pinus caribaea var. hondurensis. Foram instalados dois progênie Tibagi, PR, setembro 1988. Dados crescimento formas da árvore foram obtidos aos cinco anos idade. A produtividade volumétrica média obtida foi 0,091 m³ árvore. Para estabelecer um pomar sementes mudas, (no bloco) 190 árvores (95 procedência) com os maiores...

Rosewood (Aniba rosaeodora Ducke) is an endangered tree that produces essential oil of high commercial value. However, technical-scientific knowledge about cultivation scarce and studies are needed to examine the management viability. The current study evaluated rosewood aboveground biomass management, measuring export nutrients resulting from harvesting testing sustainable models. crown 36 trees were pruned 108 cut at 50 cm above soil in two regions Central Amazonia. Post-harvest...

Forest plantations may minimize the effects of deforestation in Amazon. However, there are differences among species terms their influences on soil recovery. The monospecific Acacia mangium, Dipteryx odorata, Jacaranda copaia, Parkia decussata,and Swietenia macrophylla, and areas pasture native forest chemical attributes Brazilian Amazon were evaluated. One bulked sample was collected per plot (0.00-0.05, 0.05-0.10, 0.10-0.30 m; three plots 128 m2) each area. No significant most observed...

Rosewood (Aniba rosaeodora Ducke) is an endangered Amazonian tree species which produces one of the most valuable essential oils in world. The used silvicultural systems are seen as a means to reducing pressure exploitation natural rosewood populations. There no specific equations for plantations, and therefore generalized inappropriate commercial systems. This study presents allometric from 144 trees sampled different plantations Central Amazonia. generated were compared with equation...
