Biologia floral e fenologia reprodutiva do camu-camu (Myrciaria dubia (H.B.K.) McVaugh, Myrtaceae) no Estado Pará, Brasil
Provedor de dados: 88
Autores: MAUÉS,MÁRCIA  M.; COUTURIER,GUY.
O camu-camu (Myrciaria dubia (H.B.K.) McVaugh, Myrtaceae) é uma fruteira nativa que ocorre nas margens de rios e lagos inundáveis da Amazônia, e está sendo domesticada visando o cultivo em terra firme. O alto teor de ácido ascórbico nos frutos, cerca de 2.800 mg.100g-1 de polpa, fortalece a demanda para consumo no país e exportação. No período de 1997 a 1998, investigou-se a biologia floral e fenologia reprodutiva do camu-camu, em plantios da Embrapa Amazônia Oriental, em Belém, e em áreas de ocorrência natural, em Santarém e Oriximiná, no Estado do Pará, norte do Brasil. Observações diretas sobre o comportamento dos visitantes foram acompanhadas da coleta de espécimens para identificação e registro fotográfico. M. dubia apresenta inflorescências com...

Abstract  Sete-capote tree, a neglected species, has great ecological, cultural and potential economic importance, however, studies for this and other native species of the Myrtaceae family are still scarce. The objective of this study was to elucidate aspects of pollen germination and viability of this specie. For the experiment, pollen from flowers in pre and post anthesis was used, which was dehydrated in a chamber containing silica, for different periods. For germination tests, different concentrations of sucrose, boric acid and calcium nitrate were used. After obtaining germination results above 80%, the pollen grains were stored in refrigerator (5 °C), freezer (-17 °C), liquid nitrogen (-147 °C) and natural environment (± 25 °C), evaluating monthly...

Spondias mombin and Theobroma grandiflorum in agroforestry system: productivity implications
Provedor de dados: 94
Autores: Alves,Rafael Moysés; Bastos,Abel Jamir Ribeiro; Chaves,Saulo Fabrício da Silva; Fernandes,José Raimundo Quadros.
Abstract  In agroforestry systems, little is known about the influence of the dominant species on that located in the lower layer of the canopy. The aim of this study was to evaluate if S. mombin plants, when in consortium with T. grandiflorum, caused some type of depression in the performance of T. grandiflorum and also to identify the most favorable S. mombin clones for this interaction. The experiment started on February 2005. During 11 years, four levels of influence of S. mombin on T. grandiflorum caused by the proximity between species were evaluated. As response variables, the vegetative development of S. mombin and T. grandiflorum was measured; the production of eight vintages T. grandiflorum trees was computed, and the mortality rate of plants was...
