Magnetic field in coffee seed germination Ciência e Agrotecnologia
Braga Júnior,Roberto Alves; Azevedo,Roberto Luiz de; Guimarães,Renato Mendes; Reis,Leandro Vilela.
ABSTRACT The effective production of coffee seedlings faces many challenges, including seed germination. Therefore, a reduced seed germination period can be one of the most relevant contributions to enhance the testing and production of robust seedlings. The objective of this research was to evaluate the effects of a constant magnetic field on the germination of coffee seeds (Coffea arabica L.). The analyses were performed using a biospeckle laser (BSL) in conjunction with traditional seed viability tests. The coffee seeds were subjected to magnetic fields of constant intensity at values of 10 mT and 28 mT for a time interval of 6 days during their germination process. The embryo region was illuminated, and the images obtained by the BSL were processed....
