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°C and 38 μmol•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.
