“…However, due to the high acidity, the fruits are rarely consumed fresh (Ribeiro et al 2010). Fruit production and processing have become a viable alternative in the general development of fruit production in the Amazon, as a food source and a means of adding value to the natural resources available in the region (Welter et al 2011, Neves et al 2015. In the Amazon, more specifically in Roraima, the occurrence of native camu-camu populations in different parts of the State is significant.…”

. The use of controlled release fertilizers is a trend for improving productivity, reducing costs and environmental pollution. Such materials release gradually the nutrients to the plant in order to supply its requirement and are an alternative to improve fertilization. The preparation of a microsphere from natural materials (chitosan and montmorilonite clay) added with nutrients, according to the needs of plants nutritional, is one of the main motivations of this work. The addition of lamellar silicates as natural clays is a promising alternative to increase water and chemical compounds sorption capacity. In the present chitosan/montmorilonite clay composites were prepared via inversion phase and thermal, structural and morphologically studies were performed. The release of the KNO 3 was realized in water using conductimetry and time domain reflectometry technique was used to monitor the in situ release in soil. Double coated microspheres provide the better nutrient encapsulation and a swelling of 200% was observed. The release was influenced by pH and fast release was observed for pH 4 and 5.5. According to the soil tests a slow release was observed since the KNO 3 delivery was accompanied during 60 days showing higher values in the first ten days and a constant value until 60 days.

“…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.
