Se realizaron tres tratamientos electromagnéticos (2,00; 4,00 y 6,00 mT), para lo cual se empleó un dispositivo estimulador electromagnético local (BioNaK-03) (Patente No.22602/1999). Cada inducción se aplicó en 100 semillas sin embeber (SSI) por tratamiento y la misma cantidad a semillas en imbibición (SCI), durante 9 min. Se establecieron dos grupos control (SSE y SCI) a los cuales no se aplicó tratamiento electromagnético. Se evaluó el porcentaje de germinación, la rapidez de germinación, la longitud del brote y la raíz. Al finalizar se obtuvo un incremento del 13,3 % de germinación en las semillas imbibidas y tratadas con 2,00 mT, y reducción del 54 % de este parámetro para 4,00 mT en semillas sin imbibición. De igual forma, el mayor valor en la longitud del brote en las plántulas de habichuela se obtuvo para las plantas que recibieron el tratamiento electromagnético, mientras que se observó una reducción en la longitud de la radícula para el tratamiento de 6,00 mT. Los resultados, aunque no son del todo concluyentes, evidencian que la aplicación de un tratamiento magnético de 2,00 mT durante 9 minutos mejoró el porcentaje y rapidez de germinación, así como el crecimiento de los brotes en semillas de V. unguiculata.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT The 60 Hz electromagnetic field effects during the germination process in seeds of Vigna unguiculata L. with more than one year of storage was determined. Three electromagnetic treatments (2.00; 4.00 and 6.00 mT) were performed. A local electromagnetic stimulator device (BioNaK-03) (Patent No.22602/1999) was used. Each induction was applied to 100 seeds without imbibition (SSI) per treatment and the same to imbibition seeds (ICS) during 9 minutes. Two control groups (SSI and SCI) were established. Percentage of germination, germination speed and length of shoot and radicle were evaluated. At the end, 13.3 % of germination in imbibed and treated seeds with 2.00 mT was increased. A reduction in 54 % of this parameter to 4.00 mT in seeds without imbibition was obtained. Likewise, the highest value in shoot length in the seedlings of green bean for the plants that received the electromagnetic treatment was observed. At the same time, a reduction in the length of the radicle for the treatment of 6.00 mT was obtained. The results, although not entirely conclusive, show that the application of a magnetic treatment of 2.00 mT for 9 minutes improved the germination and growth of V. unguiculata seeds.]]></p></abstract>
