Zusammenfassung: | The accelerated aging test is recognized as an efficient method for evaluating the vigor of seed lots and for estimating their storage potential. Thus, this work aimed to evaluate the association between artificial aging and natural storage of coffee seeds, through the correlation factor analysis. Seeds of four cultivars of Coffea arabica L. (Catuaí Amarelo, Arara, Catiguá, and Mundo Novo) and one of Coffea canephora Pierre (Apoatã) were used. Part of the newly-harvested seeds were aged in a growth chamber under controlled temperature and relative humidity conditions (42 ºC and 100% RH) for periods of 0, 4, 6, 8, and 10 days. The other part of the seeds was stored in tri-wall paper packaging for a period of 2, 4, and 6 months in a non-climate-controlled environment. Artificial aging allows predictions on the storage potential of coffee seeds, although the artificial aging periods depend on the cultivars.
Resumo: O teste de envelhecimento artificial tem se destacado como um método eficiente para avaliar o vigor de lotes de sementes e para estimar o potencial de armazenamento dos mesmos. Assim, este trabalho teve o objetivo de avaliar a associação entre o envelhecimento artificial e o armazenamento natural de sementes de café, por meio da correlação via análise de fatores. Foram utilizadas sementes de quatro cultivares de Coffea arabica L. e uma de Coffea canephora Pierre. Parte das sementes recém-colhidas foi envelhecida em câmara de crescimento do tipo BOD sob condições controladas de temperatura e umidade relativa (42 ºC e 100% UR) por períodos de 0, 4, 6, 8 e 10 dias. A outra parte das sementes foi armazenada em embalagens de papel trifoliado por um período de 2, 4 e 6 meses em armazém, em ambiente não controlado. O envelhecimento artificial prediz a armazenabilidade de sementes de café, sendo os tempos de envelhecimento artificial dependentes das cultivares. |
