Resumo: | The species Ananas comosus var. erectifolius, known as curauá, belongs to the family of Bromeliaceae, in the Amazon region its foliage has benefits in the production of fibers and is also considered a medicinal species. Despite its importance, research on the behavior of phenology of species with great economic potential in the Amazon is scarce. The objective of this work was to study the reproductive phenophases of Ananas comosus var. erectifolius belonging to the Active Germplasm Bank of Embrapa Amazônia Oriental correlating with air temperature and rainfall, in order to indicate the most suitable time for the collection and use of plant material of the species. The frequencies were recorded weekly from January 2015 to December 2019. Phenological activity showed differences between accesses. The Spearman correlation index showed a direct and significant correlation only in fruiting in relation to temperature. The phenological record showed the maximum concentration of groups of accessions that had the highest average flowering days in August, September and October, especially in August. Fruiting recorded the highest average percentage of fruiting days in August, September, October and November, especially in October. It is suggested the collection of plant material of interest to the species from December to July, whose registration of the number of days that occur the phenophases undergoes reductions. It is pertinent to carry out further studies on the correlation of phenology with climatic events considering the performance of each access individually. |

A pesar de su importancia, las investigaciones sobre el comportamiento de la fenología de especies con gran potencial económico en la Amazonía son escasas. El objetivo de este trabajo fue estudiar las fenofases reproductivas de Ananas comosus var. erectifolius perteneciente al Banco de Germoplasma Activo de Embrapa Amazônia Oriental correlacionando con la temperatura del aire y las precipitaciones, a fin de indicar el momento más adecuado para la recolección y uso del material vegetal de la especie. Las frecuencias se registraron semanalmente desde enero de 2015 hasta diciembre de 2019. La actividad fenológica mostró diferencias entre accesos. El índice de correlación de Spearman mostró una correlación directa y significativa solo en fructificación en relación a la temperatura. El registro fenológico mostró la máxima concentración de grupos de accesiones que tuvieron los días de floración promedio más altos en agosto, septiembre y octubre, especialmente en agosto. La fructificación registró el mayor porcentaje de días de fructificación en agosto, septiembre, octubre y noviembre, con un destaque en octubre. Se sugiere la recolección de material vegetal de interés para la especie de diciembre a julio, cuyo registro del número de días que ocurren las fenofases sufre reducciones. Es pertinente realizar más estudios sobre la correlación de la fenología con los eventos climáticos considerando el desempeño de cada acceso de manera individual. A espécie Ananas comosus erectifolius, conhecida como curauá, pertence a familia das Bromeliáceas, na região amazônica sua folhagem tem proveito na produção de fibras e também é considerado uma espécie medicinal. Apesar da sua importância, pesquisas sobre o comportamento da fenologia de espécies com grande potencial econômico da Amazônia são escassas. O trabalho teve como objetivo realizar o estudo das fenofases reprodutivas de Ananas comosus var. erectifolius pertencente ao Banco Ativo de Germoplasma da Embrapa Amazônia Oriental correlacionando com a temperatura do ar e a precipitação pluviométrica, com a finalidade de indicar a época mais adequada para a coleta e utilização do material vegetal da espécie. As frequências foram registradas semanalmente de janeiro de 2015 a dezembro de 2019. A atividade fenologica exibiu diferenças entre acessos. O índice de correlação de Spearman apontou uma correlação direta e significativa apenas na frutificação em relação à temperatura. O registro fenológico mostrou a máxima concentração de grupos de acessos que apresentaram maiores médias de dias de floração em de agosto, setembro e outubro, com destaque em agosto. A frutificação registrou as maiores médias percentuais de dias de frutificação em agosto, setembro, outubro e novembro, com destaque em outubro. Sugere-se a coleta de material vegetal de interesse da espécie de dezembro á julho, cujo registro de número de dias que ocorrem as fenofases sofre reduções. È pertinente executar posteriores estudos de correlação da fenologia com eventos climáticos considerando individualmente o desempenho de cada acesso.
