Interpretação fenológica de espécies lenhosas de Campina na Reserva Biológica de Campina do INPA ao Norte de Manaus

The author presents phenological observations of 27 Campina woody species in the Campina Biological Reserve - INPA, 60 Km on north of Manus, during the period of August/77 to July/86. The majority of species presented complete flowering during dry season. This behavior was presented also by Shaded c...

The majority of species presented complete flowering during dry season. This behavior was presented also by Shaded campina species. In the transition of Shaded campina to Opened campina there was a tendency of complete flowring either during dry or wet season. The Opened campina species presented this phenophase during wet season and during the transition to dry season. The transition species and those of Opened campina have show different behaviors in comparison with the majority woody species of the tropical rain forest. It was determined twelve species with annual flowering; three species was flowering regularly during all the months, every year; eight species had two flowering in the same year; three species had irregular flowering and only one species flowered in intervals of three years. Twenty species presented perenial leaves, apparently without change of leaves. The axis 1, and 3 represented complete flowering, new leaves and mature fruits, respectively.Through the correlation circles it was verified two different periods to these phases in dry and wet seasons. Accordin to the plane representation in the axis it was determined species in oposition and with similar behavior in reference to the phases analyzed. O autor apresenta resultados de observações fenológicas de 27 espécies lenhosas de campina, na Reserva Biológica de Campina do INPA, 60 Km ao Norte de Manaus, colhidas no período de agosto/77 a julho 86. A maioria das espécies apresentou a plena floração na estação seca, comportamento mostrado pelas espécies de Campina Sombreada; na transição da Campina Sombreada para a Campina Aberta houve tendência da plena floração ocorrer tanto na estação seca quanto na chuvosa e as espécies de Campina Aberta tiveram esta fase na estação chuvosa e na transição para a seca. Os comportamentos das espécies de transição e as de Campina Abertamostraram-se diferentes da maioria das espécies arbóreas de floresta tropical úmida. Verificou-se que 12 espécies apresentaram floração anual; 3 espécies floresceram regularmente durante todos os meses do ano; 8 espécies tiveram floração irregular e somente uma espécie floresceu em intervalos de 3 anos. Vinte espécies comportaram-se como perenifólias, sem troca de folhas, aparentemente. Numa análise dos componentes principais para a plena floração, folhas novas e frutas maduros, os eixos 1,8 e 3 definiram estas fases, respectivamente. Os círculos de correlações mostraram que existiram duas épocas de ocorrência distintas destas fases (estação seca e estação chuvosa). A representação plena em 3 eixos indicou as espécies em oposição e com comportamento similar, quanto às três fases analisadas. 2020-04-24T15:48:43Z 2020-04-24T15:48:43Z 1990 Artigo https://repositorio.inpa.gov.br/handle/1/13828 10.1590/1809-43921990201183 pt_BR Volume 20, Pags. 145-183 Attribution-NonCommercial-NoDerivs 3.0 Brazil http://creativecommons.org/licenses/by-nc-nd/3.0/br/ application/pdf Acta Amazonica
