“…In the state of Roraima, extreme north of Brazil, the occurrence of native camu-camu populations is significant, but the fruit availability is not continuous due to its production being seasonal, that is, influenced by the edaphoclimatic factors (Abanto et al, 2016;Chagas et al, 2015). In addition, due to camu-camu is a species which is in the domestication process, little is known about the ideal conditions of planting on dry land, due to the lack of work aimed at this line of research (Viégas et al, 2004).…”

Camu-camu (Myrciaria dubia (Kunth) McVaugh) is a native fruit tree, which is in domestication process, therefore, knowledge of nutritional needs is essential to improve the fertilization efficiency throughout plant development. The aim of this research was to determine the nutrient content of camu-camu plants as a function of nitrogen fertilization via fertirrigation in the first year of cultivation. An experiment was carried out in a randomized complete block design, with 5 treatments as follows: 0; 40; 80; 120 and 160 kg.ha -1 of N, eight replicates and seven plants per experimental unit. The evaluated variables were as follows: total dry matter and nutrient contents in camu-camu leaves. The results show total dry matter of camu-camu plants, which were performed a significant quadratic behavior in response to increasing N doses. In Fact, N doses greater than 128 kg.ha -1 aroused a depressive effects. In addition, leaf contents of N, K, and Ca, had achieved a significant quadratic response and highest concentrations were recorded between 113 and 115 kg of N.ha -1 . On the other hand, micronutrients had a polynomial depressive behavior according to an increasing N doses. It can be concluded that nutrient foliar contents are adequate for the camu-camu plants development. In fact, N, Ca, K, Fe, Mn and B, were the most required nutrients. Micronutrients determined in leaves, corresponded to the following decreasing order: N> Ca> K> Mg> S> P> Mn> Fe> B> Zn> Cu, respectively. Key Words: Dry matter, micronutrients, nutrient balance (plants), plant development, plant nutrition. ResumoO camu-camu (Myrciaria dubia (Kunth) McVaugh) é uma fruteira nativa que está em processo de domesticação, portanto, o conhecimento das necessidades nutricionais é essencial para melhorar a eficiência da adubação durante seu desenvolvimento. O trabalho teve como objetivo determinar os teores de nutrientes em plantas de camu-camu em função da adubação nitrogenada via fertirrigação no primeiro ano de cultivo. O experimento foi conduzido mediante delineamento experimental em blocos casualizados, com 5 tratamentos: 0; 40; 80; 120 e 160 kg ha -1 de N, oito repetições e sete plantas por unidade experimental. As variáveis avaliadas foram a massa seca total e os teores de nutrientes nas folhas. Os resultados mostram que a massa seca total das plantas de camu-camu apresentou comportamento quadrático significativo em resposta às doses crescentes de N, sendo que doses maiores a 128 kg ha -1 propiciaram efeitos depressivos. Além disso, os teores foliares de N, K, Ca tiveram uma resposta quadrática significativa, sendo que as maiores concentrações foram registradas entre as doses de 113 e 115 kg de N ha -1 . Por outro lado, os micronutrientes tiveram um comportamento polinomial depressivo de acordo com os incrementos das doses de N. Pode-se concluir que os teores foliares dos nutrientes estão dentro dos adequados para o desenvolvimento das plantas de camu-camu, e os nutrientes mais exigidos foram o N, Ca, K, Fe, Mn e B, e finalmente os teores de...

“…The increasing interest in camucamu fruit is due to its remarkable ascorbic acid (vitamin C) content, and it is known as "King of Vitamin C" or "Super Fruit". In the state of Roraima, Brazil, the fruit is known as 'caçari', presenting mean values of 3,571 to 7,355 mg ascorbic acid 100 g -1 pulp (Aguiar and Souza, 2016;Chagas et al, 2015;Grigio et al, 2015;Grigio et al, 2016). In addition to vitamin C, these fruits contain other antioxidant compounds, such as carotenoids, anthocyanins and other phenolic compounds which are valuable in human nutrition (Silva, 2012).…”

Camu-camu fruits have high functional importance and great potential as food. Knowing and determining the nutrients present in its fruitsis crucial, in order to understand the relationship between consumption and human health. For this reason, the objective of this work was to evaluate qualitative attributes, such as organic acids content, antioxidant capacity and functional potential of different parts of camu-camu fruit. The fruit used in the present study were collected in the state of Amazonas, Brazil, and analyzed at the University of Florida, Gainesville, U.S.A. Seed, peel, pulp, pulp+peel, and whole fruit were evaluated regarding pH, soluble solids, titratable acidity, and levels of ascorbic acid, phenolic compounds, anthocyanins, and flavonoids. Antioxidant activity was evaluated by the Ferric Reducing Antioxidant Power (FRAP) and Diphenyl-1-picrylhydrazyl (DPPH) methods. Based on the results, camucamu fruit proved to be a good source of acids, and the pulp is the part that is most concentrated in organic acids. Also, the pulp presents the highest amount of phenolic compounds and highest antioxidant activity. The peel had relatively higher amount of pigments, anthocyanins and flavonoids, and higher concentration of ascorbic acid, proving that it can also be used as a source of bioactive compounds.

“…The camu-camu (Myrciaria dubia (kunth) McVaugh), is an Amazonian fruit species of the Mirtaceae family, that stands out for its elevated level of vitamin C, which can reach from 3 to 8 g per 100 g of pulp, exceeding values presented by the majority of plants cultivated in Brazil (Bardales et al, 2014;Chagas et al, 2015), in addition to containing diverse antioxidant and nutritional composites (Zanata & Mercadante, 2007;Chirinos et al, 2010;Akter, Oh, Eun, & Ahmed, 2011;Imán, Pinedo, & Melchor, 2011).…”

“…It also constitutes a raw material for the cosmetic, chemical, pharmacological industries, food preservation and production of aerated beverages (Correa, 2000;Yuyama, 2011). Thus, the production and the utilization of the fruit appear to be viable alternatives in regional development, as a means of aggregating value from the natural resources available in the region (Welter et al, 2011;Chagas et al, 2015).…”

The objective in the present work was to evaluate the genetic diversity among 15 indigenous populations of camu-camu plants, identifying important characteristics in the evaluation of genetic divergence, based on the initial characteristics of the seedlings. Seeds extracted from fruits deriving from fifteen indigenous populations of camu-camu were collected. The experimental design was entirely random, with fifteen treatments (populations), and fifteen repetitions (each sub-sample), considering 30 seeds per subsample as an experimental unit. At 40 days after sowing the following were evaluated: the percentage of emergence, the index of emergence velocity, the average time of germination, the height of the seedling and the number of leaves. The data obtained was submitted to variance analysis, and the averages were grouped by the Scott and Knott (1974) test. The genetic diversity was studied according to the Tocher grouping method, based on the Mahalanobis distance (D 2 ii ) and canonical variables. The fifteen populations are divergent among themselves and the Rio Branco Estirão do Veado, Rio Branco Onofre and Igarapé Agua Boa populations are indicated to have hybridization with other populations due to the high divergence, as well as the rates of emergence and vigor of the seedlings. The height of the seedlings, percentage and speed of emergence, are those that most indicate genetic divergence. The measuring techniques of genetic divergence, canonical variables Mahalanobis distances are useful and corroborating in the evaluation of genetic divergence of the camu-camu plant.
