Effect of the Intensity and Duration of Light at Various Temperatures on the Germination of Oldenlandia corymbosa L. Seeds

摘要

At temperatures below 35 to 40°C, fairly intense continuous white light (13 watts per square meter) inhibits germination of Oldenlandia corymbosa L. seeds, and the lower the temperature, the greater the inhibition. However, such lighting may enable seeds to germinate later in the dark; their degree of germinability depends both on the duration of lighting and on the temperature during lighting and after transfer to the dark.
