Resumo: | This study aimed to describe the phenology of a natural population of Elaeis guineensis (oil palm), located on the Academic Unit Specialized in Agricultural Sciences UFRN in Macaíba, RN state, evaluating reproductive and vegetative phenological phases of plants and the climate. Phenological characteristics concerning leafiness, defoliation, blooming and fruiting, evaluated using the activity index and intensity of Fournier recorded biweekly from October 2012 to March 2014. The relationship between climate and the phenological phases was performed by Spearman correlation. Elaeis guineensis showed no emission of buds and flowers. The loss and leaf emergence occurred during the whole time. The activity of immature fruits showed significant positive correlation with temperature (rs = 0.336, P = 0.03). The intensity and activity of mature fruits showed, respectively, a significant positive correlation with both humidity (rs = 0.455, P = 0.004 and rs = 0.416, P = 0.009) and with rainfall (rs = 0.614, P = 0.00004 and rs = 0.578, P = 0.0001), indicating that the higher humidity and precipitation, the greater the production of the ripe fruit is. |

Foram registradas quinzenalmente, de outubro de 2012 a março de 2014, as características fenológicas referentes a enfolhamento, desfolhamento, antese e frutificação, avaliadas por meio do índice de atividade e intensidade de Fournier. A relação entre as variáveis climáticas e as fenofases foi realizada por meio da correlação de Spearman. Elaeis guineensis não apresentou emissões de botões e flores no período avaliado. A perda e a emissão de folhas ocorreram durante todo o tempo. A atividade de frutos imaturos apresentou correlação significativa e positiva com a temperatura (rs= 0,336; P= 0,03). A intensidade e a atividade dos frutos maduros apresentaram, respectivamente, correlação positiva e significativa tanto com a umidade (rs= 0,455; P= 0,004 e rs= 0,416; P= 0,009) quanto com a precipitação (rs= 0,614; P= 0,00004 e rs= 0,578; P= 0,0001), indicando que quanto maior umidade e precipitação, maior é a produção de frutos maduros.Universidade Federal de Santa Maria2019-12-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/2264010.5902/1980509822640Ciência Florestal; Vol. 29 No. 4 (2019); 1701-1711Ciência Florestal; v. 29 n. 4 (2019); 1701-17111980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/22640/22640Copyright (c) 2019 Ciência Florestalinfo:eu-repo/semantics/openAccessChagas, Kyvia Pontes Teixeira dasCarvalho, Brenda Lívia Barbosa deGuerra, Cynthia Azevedo GurgelSilva, Richeliel Albert RodriguesVieira, Fábio de Almeida2019-12-10T21:30:48Zoai:ojs.pkp.sfu.ca:article/22640Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2019-12-10T21:30:48Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
