Oldenlandia corymbosa seeds can only germinate in the light and at very high temperatures (optimum at 35–40°C). Two types of seeds exist: those that germinate rapidly in continuous white light at 35–40°C are regarded as “non-dormant”; the others which are unable to germinate under the same conditions without having been treated for some days at a fairly low temperature (<25°C) in a wet medium are “dormant”. The requirement for high germination temperatures is characteristic of the embryo, while the absolute need for light and the inability of dormant seeds to germinate are characteristic of the endosperm and seed coat. The dormancy of these seeds is, in fact, an inhibition caused by the structures covering the Oldenlandia embryo. Seeds are hypersensitive to oxygen. At the optimal germination temperature some of them germinate rapidly within a wide range of oxygen partial pressures. They germinate particularly well in the air. These are the so-called “non-dormant” seeds. Others germinate well at this temperature only in atmospheres containing 5–10% oxygen. These seeds, which germinate with difficulty in the air, are the “dormant” ones. If dormant seeds do not germinate in the air, it is thus because of an excess of oxygen. Again, this phenomenon is caused by the endosperm and the seed coat and not by the embryo. These peculiarities in the germination of Oldenlandia corymbosa seeds are probably bound up with the tropical climate.
