Abstract

Potato plantlets (Solanum tuberosum L. cv. Benimaru) were cultured in vitro for 20 days on a 10 ml MS agar medium under a magnetic flux density of 0 (control: Cont), 2, 4 or 6 mT (T=Wb m-2) in both upward and downward directions of magnetic field. Air temperature in the head space of the test tubes and photosynthetic flux density on the culture shelf were 25 +/- 1 degrees C and 38 micromoles m-2 s-1 respectively. The results showed that a magnetic flux density of around 4 mT had beneficial effects, regardless of the direction of magnetic field, on the growth promotion and enhancement of CO2 uptake of potato plantlets in vitro The direction of magnetic field at the magnetic flux densities tested had no effects on the growth and CO2 exchange rate.
