Longevity camu-camu seeds submitted to different storage environment and forms ...
Yuyama, Kaoru; Mendes, Nalu Bandeira; Valente, João PedroCamu-camu (Myrciaria dubia (H.B.K.) McVaugh) contains great potential for ascorbic acid extraction, which has economic and social importance, with innumerable industrial applications. The objective of this work was to evaluate the effect of different storage environment and forms of conservation for maintaining the viability of camu-camu seeds. The experimental design was randomized blocks design in split-split...

Asexual propagation of peach palm by division of the clump and extraction of th...
Flores, Wanders B.Chávez; Yuyama, Kaoru; Silva, Raimundo G. daThe peach palm (Bactris gasipaes) is a native Amazonian palm tree that produces fruits and palm hearts, and is now attracting the interest of the farmers in other parts of Brazil given the economical potential of palm heart production. Traditionally the peach palm is propagated by seeds, which yield segregating progenies due to cross-pollination. To guarantee the uniformity and quality of elite selections, the ...
Large cuttings of camu-camu with indolebutyric acid for clonal production
Delgado, Jhon Paul Mathews; Yuyama, KaoruThe fruit of camu-camu is attractive because of its high vitamin C content (877 to 6113 mg/100 g of pulp). Its propagation normally is by seed, which segregate for different characteristics of commercial interest; hence a vegetative propagation method would allow better uniformity. This study evaluated the effect of indolebutyric acid - AIB (0 and 200 mg L-1) on the rooting of young branches of camu-camu (5, 10...

Physicochemical characterization of acai juice of Euterpe precatoria Mart. from...
Yuyama, Lucia Kiyoko Ozaki; Aguiar, Jaime Paiva Lopes; Filho, Danilo Fernandes Silva; Yuyama, Kaoru; Varejão, Maria de JesusThe fruit of açaí (Euterpe precatoria Mart.) from different Amazon ecosystems were processed to obtain the juice. The juice obtained from each ecosystem was evaluated for proximate composition (moisture, ash, lipids, protein, carbohydrates and dietary fiber), minerals, fatty acids and anthocyanins. The fruits prior to processing were compared in terms of weight, having noticed a significant variation from 1.1 t...
Effect of density and fertilization NPK on heart-of-palm production of peach palm
Yuyama, Kaoru; Chávez Flores, Wanders Benjamin; Pereira, Bianca G.; Silva, Ildelfonso A.The effect of density and fertilization on heart-of-palm yield of peach palm under field conditions was determined at Yuricam farm, in Rio Preto da Eva counnty, state of Amazonia, Brazil. The experiment was installed in a randomized complete block design. Treatments were arranged in a 3 × 5 factorial scheme with three replicates. Treatments were comprised of the planting density (10,000; 5,000 and 3,333 plants ...
