Resumo: The objective of this work was to obtain a mathematical model of the longevity of camu-camu seeds (Myrciaria dubia (H.B.K.) McVaugh). Experimental data from the bibliography of the survival curves of camu-camu seeds, stored under different moisture contents and temperatures, were used in linear and non linear regressions for determining the coefficients of different longevity models. The coefficients of the recommended models were determined using the values of germination and emergence losses, initial germination and emergence, temperature, average moisture content of the seeds and the storage period for all survival curves. The modified probit model was recommended because it resulted in the best fits for the 57 experimental observations when compared with other three models, as well as for germination loss (R2 of 0.90, standard error of 12.3%, and all model coefficients significant at 0.4% probability level in the t test) and emergence loss (R2 of 0.87, standard error of 13.3%, and all model coefficients significant at 0.1% probability level in the t test).

McVaugh). Dados experimentais da bibliografia referentes às curvas de sobrevivência de sementes de camu-camu, armazenadas sob teores de água e temperaturas, foram utilizados em regressões lineares e não lineares para determinação dos coeficientes de diferentes modelos de longevidade. Os coeficientes dos modelos recomendados foram determinados usando-se os valores das perdas da germinação e emergência, da germinação e emergência iniciais, da temperatura, do teor médio de água das sementes e do período de armazenagem, para todas as curvas de sobrevivência. O modelo modificado de probit foi recomendado porque resultou no melhor ajuste para 57 observações experimentais, quando comparado com outros três modelos, tanto para a perda da germinação (R2 de 0,90, desvio padrão de 12,3% e grau de significância dos coeficientes do modelo menor que 0,4% de probabilidade de erro no teste t), como para a perda da emergência (R2 de 0,87, desvio padrão de 13,3% e grau de significância dos coeficientes do modelo menor que 0,1% de probabilidade de erro no teste t).Universidade Federal de Viçosa - UFV2015-07-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/42610.13083/reveng.v23i3.470Engineering in Agriculture; Vol. 23 No. 3 (2015); 203-211Revista Engenharia na Agricultura - REVENG; v. 23 n. 3 (2015); 203-2112175-68131414-398410.13083/reveng.v23i3reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/426/306Sinício, Robertoinfo:eu-repo/semantics/openAccess2019-10-23T18:59:06Zoai:ojs.periodicos.ufv.br:article/426Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2019-10-23T18:59:06Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false
