COMPORTAMENTO FENOLÓGICO DA SUCUPIRA-PRETA (Diplotropis purpurea (Rich.) Amsh. var. coriacea Amsh.), NA RESERVA FLORESTAL DUCKE

Abstract

RESUMO -Este trabalho analisa dados de 6 anos (1980)(1981)(1982)(1983)(1984)(1985) de observações da fenologia de cinco indivíduos arbóreos da espécie Diplotropis purpures (Rich.) Amsh. var. coriacea Amsh., da família Leguminosae, subfamília Papilionoideae, localizados na Reserva Florestal Ducke. Determinou-se a época, duração e freqüência das fases reprodutivas, bem como o tipo de mudança foliar. A espécie apresentou a fase de floração na estação seca. A fase de frutificação foi observada no meio da estação seca e início da estação chuvosa. A duração média da fase de floração foi de 6 meses e a fase de frutificação 7 meses. Ao nível de espécie, o padrão de ocorrência da fase de floração e frutificação foi anual à irregular. Porém, ao nível de indivíduo, o padrão de comportamento foi irregular. Quanto ao tipo de mudança foliar, a espécie apresentou características de ser semi-caducifólia durante a floração, na época seca.

ABSTRACT -This work analyses phenological data during the period from 1980 to 1985 ofDiplotropis purpurea (Rich.) Amsh. var. coriacea Amsh. -Leguminosae -Papilionoideae, located at Ducke Forest Reserve, including flowering, fruiting and leaf change. The period of time, duration and frequency of reproductive phases are reported, as well as the type of leaf change. The species showed the flowering phase in the dry season. The fruiting phase was observed in the middle of dry season and at the beginning of wet season. The duration of the flowering and fruiting was about 6 and 7 months. In reference to the occurrence of flowering and fruiting both were annual to irregular, although at the individual level the behavior was irregular. Considering the leaf changes the species showed a semi-deciduous pattern during the flowering, in the dry season.

Reproductive phenology of Carapa guianensis Aubl. (Meliaceae) in two forest areas of the Central Amazon

“…Maximum temperatures ranged from 31. o C. There is also a less humid period between June and October, with less constant rainfall, but no water deficit. In this period, there was an average rainfall of 121 mm per month and higher temperatures of 32,5 o C, considered as the dry season.…”

“…The greatest number of trees (3)(4)(5) per month the mature fruit occurred in the years 1974 (Feb) and 1983 (May and Jun). But without mature fruit was observed in 1975, from 1977 to 1981, 1984, 1986, 1988, 1989, 1991, 1992, from 1994 to 1996, and 1998 until (Fig 5B).…”

“…This research has generated several publications on the phenology of trees in the Central Amazon, which analyze the data collected in the ADFR. The former studied the phenology of Amazonian forest species occurred in a period of seven years (1962)(1963)(1964)(1965)(1966)(1967)(1968) and the latter analyzed the phenology of forest species in upland tropical rainforests in the Central Amazon [1,2,3,4,5,6,7,8].…”

“…Also, was analyzed the phenological behavior of Diplotropis purpurea Rich. (Fabaceae) in six years (1980)(1981)(1982)(1983)(1984)(1985) [5]. Among the studies on families, two must be highlighted: the phenology of five species of Lecythidaceae over an eleven-years period (1978)(1979)(1980)(1981)(1982)(1983)(1984)(1985)(1986)(1987)(1988) [6] and the phenology analysis of five species of Sapotaceae in one twenty-oneyear period [7].…”
