ABSTRACT
In vitro coffee seedlings were exposed to an electromagnetic field (EMF) of 2 mT during 3 minutes in
establishment, multiplication, and acclimazation phases. Shoot and root lengths and leaf pair numbers of treated
groups increased when compared to control; in addition to SOD, CAT, and APX activities of in vitro-treated
groups showed a decrease in levels. Four months after the magnetic treatment was applied, the same parameters
were evaluated. Shoot lengths, root lengths, the pair of leaves numbers, and CAT activity increased in
treated plants. APX activity decreased in treatment seedlings, whereas SOD activity did not show a difference
between experimental groups.
