The growth rate of excised soybean (Glycine max [L.] Merrill) embryos grown in liquid culture increased linearly as photoperiod was increased from 0 to 20 h at an irradiance of 9 W m-2 measured between wavelengths of 700-850 nm from clear incandescent lamps. When irradiance levels were varied between 0.1 and 1.7 W m-2, the maximum growth rates of embryos occurred at ca. 0.5 W m-2 at both 10- and 16-h photoperiods. When the light source was changed from clear incandescent lamps, with a red (600-700 nm) to far-red (700-770 nm) ratio of ca. 1.07, to a BCJ incandescent lamp (Corning Glass dark red, transparent envelope and a red to far-red ratio of ca. 0.19), the growth rate of embryos slowed. These results are consistent with a high irradiance response for growth of soybean embryos.
在液体培养中生长的切除大豆（Glycine max [L.] Merrill）胚的生长速率，在来自透明白炽灯、波长在700 - 850 nm之间测量的9 W m-2辐照度下，随着光周期从0小时增加到20小时呈线性增加。当辐照度水平在0.1和1.7 W m-2之间变化时，在10小时和16小时光周期下，胚的最大生长速率均出现在约0.5 W m-2处。当光源从红色（600 - 700 nm）与远红色（700 - 770 nm）比例约为1.07的透明白炽灯，改为BCJ白炽灯（康宁玻璃深红色，透明外壳，红色与远红色比例约为0.19）时，胚的生长速率减慢。这些结果与大豆胚生长的高辐照度响应一致。
