Abstract

In this study, in vitro tissue cultures of Paulownia tomentosa and Paulownia fortunei were prepared and then exposed to a magnetic flow density of 2.9-4.8 mT and 1 m s(-1) flow rate for a period of 0, 2.2, 6.6 and 19.8 s. The magnetic field (MF) increased the regeneration capability of Paulownia cultures and shortened the regeneration time. On the 28th day of culture, the positive effect of magnetic field on plant fresh weight, length, number of leaves and chlorophyll content in node explants of P. tomentosa and P. fortunei was observed. It was found that this effect varied with exposure time. When the cultures were exposed to a magnetic field with strength of 2.9-4.8 mT for 19.8 s, the regenerated P. tomentosa and P. fortunei plants dominated the control plants.
