Estudo fenológico de espécies arbóreas nativas em uma unidade de conservação de caatinga no Estado do Rio Grande do Norte, Brasil

Abstract: A fenologia observa o desenvolvimento vegetativo e reprodutivo das plantas e a interferência que fatores bióticos e abióticos realizam em cada evento fenológico. Entretanto, estudos fenológicos são ainda incipientes em florestas tropicais secas, especialmente no Semiárido brasileiro. Assim, objetivou-se estudar a fenologia de seis espécies lenhosas da caatinga (Dipteryx odorata, Cordia oncocalyx, Poincianella pyramidalis, Manihot pseudoglaziovii, Handroanthus heptaphyllus e Pseudobombax cf. marginatum), além d… Show more

“…A considerable fraction of woody savanna species bloom at the beginning of the rainy season, while others produce flowers during periods of high water stress (Monasterio and Sarmiento 1976;Batalha and Mantovani 2000;Ramirez 2002;Gottsberger and Silberbauer-Gottsberger 2006;Pirani et al 2009). It is well established that woody species growing in seasonally dry forests tend to flower at the end of the dry season and/or beginning of the rainy season (Amorim et al 2009;Neves et al 2010;Lima et al 2012;Souza et al 2014) because most species are essentially dependent on water availability for flowering (Méndez-Alonzo et al 2013), although water stress can act as a trigger for this phenophase in some species (Sakai et al 2006;Larcher 2010). Plant water storage capacity, related to wood density, can also have a strong influence on plant phenology (Borchert 1994;Lima and Rodal 2010).…”

“…Em relação a produção de botões durante as chuvas, várias espécies do Cerrado e também da Caatinga apresentam comportamento semelhante ao da espécie estudada, e por isso apresentam consequentemente, a correlação positiva com a precipitação (SOARES et al, 2013;SOUZA et al, 2014;SILVA et al, 2016). Já a correlação positiva com a temperatura mínima parece ser comum, Silvério e Lenza (2010) também encontraram correlação positiva entre a floração e temperatura mínima para cinco espécies em Cerrado do Mato Grosso.…”

“…This index, therefore, allows to evaluate the synchrony of the individuals of a population. The greater the percentage of individuals in the phenophase, the more synchronized they are (Bencke & Morellato, 2002;Fournier, 1974;Souza et al, 2014).…”
