摘要
Time-lapse monitoring using infrared imaging revealed a distinct change in circumnutatory behaviour of Arabidopsis inflorescence stems by dark treatment, which drastically increased curvature and decreased nutation frequency. Re-irradiation during dark treatment had different effect on the nutation frequency and the curvature, suggesting that radiation condition controls them through different mechanism.
