Abstract:
A method using optical microfibers permitted localized exposure of the cap or the elongating part of growing maize (Zea mays L.) roots to white light. When the cap was illuminated, a strong and very rapid inhibition of the elongation rate of the roots was found. When the light microbeam was directed at the elongating region, the roots continued to grow at the same rate as before the illumination.
