“…The species is hermaphroditic and self-incompatible (Oliveira and Sigrist 2008). Pollination is mainly performed by large (Xylocopa suspecta, Apidae) and medium-size (Halictidae) bees (Oliveira and Sigrist 2008).…”

“…Studies considering the plant phenology of the cerrado savanna at species level are sparse (e.g. Goulart et al 2005, Lenza and Klink 2006, Oliveira and Sigrist 2008, Vilela et al 2008. However, the relationship between reproductive patterns and intraspecific synchrony has not been explored for cerrado savanna species, especially in the context of environmental changes (e.g.…”

The Brazilian cerrado has undergone an intense process of fragmentation, which leads to an increase in the number of remnants exposed to edge effects and associated changes on environmental conditions that may affect the phenology of plants. This study aimed to verify whether the reproductive phenology of Xylopia aromatica (Lam.) Mart. (Annonaceae) differs under different light conditions in a cerrado sensu stricto (a woody savanna) of southeastern Brazil. We compared the reproductive phenology of X. aromatica trees distributed on east and south cardinal faces of the cerrado during monthly observations, from January 2005 to December 2008. The east face had a higher light incidence, higher temperatures and canopy openness in relation to south face. X. aromatica showed seasonal reproduction at both faces of the cerrado, but the percentage of individuals, the synchrony and duration of phenophases were higher at the east face. The study demonstrated the influence of the environmental conditions associated to the cardinal orientation of the cerrado faces on the phenological pattern of X. aromatica. Similar responses may be observed for other species, ultimately affecting patterns of floral visitation and fruit production, which reinforces the importance of considering the cardinal direction in studies of edge effects and fragmentation.

“…Além de X. aromatica, como mostra este estudo, o Baru também é uma espécies que apresenta frutos maduros na época seca (OLIVEIRA; SIGRIST, 2008). A dispersão dos frutos durante a estação seca faz com que estas espécies sejam a fonte de alimento para diversos animais, em um período em que geralmente não há tantas espécies zoocóricas dispersando seus diásporos (BATALHA;MANTOVANI, 2000).…”

ESTRATÉGIAS FENOLÓGICAS REPRODUTIVAS DE Xylopia aromatica (LAM.) MART. (ANNONACEAE) EM ÁREA DE CERRADORESUMO: Apesar dos esforços empreendidos nos últimos anos, os dados sobre a fenologia das espécies do Cerrado são fragmentários e mesmo X. aromatica sendo amplamente distribuída sua fenologia é desconhecida. Neste sentido, buscou-se avaliar sua fenologia reprodutiva em um fragmento de Cerrado no Município de Rio Verde e correlaciona-la com as variáveis climáticas. Marcou-se 20 indivíduos para serem observadas mensalmente as fenofases: botão, flor aberta, fruto imaturo e maduro. Para as análises utilizou-se o percentual de Fournier, método de presença/ausência e correlação de Spearman. A emissão de botões ocorreu de modo irregular e os mesmos estiveram presentes tanto no período seco quanto no chuvoso de modo a não se correlacionar com nenhuma das variáveis. A floração ocorreu de forma distribuída ao longo do estudo se correlacionando de modo negativo apenas com a umidade relativa. A frutificação ocorreu no período seco e na transição do período seco para o chuvoso, correlacionada negativamente com a precipitação e umidade. Os frutos amadureceram nos últimos meses da estação seca e primeiros da chuvosa, se correlacionando apenas com a umidade. O ciclo reprodutivo de X. aromatica não é influenciado fortemente pelas variáveis climáticas e o fato de se correlacionar negativamente com a precipitação e umidade sugere que a espécie foi adaptada de modo a otimizar a polinização e dispersão de frutos. REPRODUCTIVE PHENOLOGICAL STRATEGIES OF Xylopia aromatica (LAM.) MART. (ANNONACEAE) IN CERRADO AREAABSTRACT: Despite efforts in recent years, data on the phenology of Cerrado species are fragmentary, and even X. aromatica being widely distributed, its phenology is unknown. In this sense, we sought to evaluate their reproductive phenology in a fragment of Cerrado in Rio Verde Municipality and correlate it with climatic variables. 20 individuals were marked to be subject to monthly phenological phases observation: bud, open flower, immature and mature fruit. For the analysis we used the percentage of Fournier, method of presence/ absence and Spearman correlation. The emission of buds occurred irregularly and was present in both the wet and in the dry period, not correlating with any of the climatic variables. Flowering occurred distributed throughout the study, negatively correlated only with relative humidity. Fruitification occurred in the dry season and in the transition from dry to rainy season, negatively correlated with rainfall and humidity. The fruits matured in the last months of the dry season and first months of the rainy season, correlating only with moisture. The reproductive cycle of X. aromatica is not strongly influenced by climatic variables and the fact that it is negatively correlated with precipitation and humidity suggests that the species was adapted to optimize pollination and dispersal of fruit.
