We know that light has a key role on different plant mechanisms, but its effect on the embryogenesis is question. Thanks for expressing the opinions of researchers.

Light quality is a very important parameter in somatic embryogenesis experiments. See below references of a recent article (March 2021) on this subject.

Yes, light sources have an impact on somatic embryogenesis. Under in vitro conditions, organogenesis, as well as somatic embryogenesis, is photo-dependent.
Yes, the nature of the color and its intensity can affect somatic embryogenesis experiments and may result in many differences among the obtained explants.
Light has an important role on several plant mechanism. Therefore, rare studies have been accomplished about kind of lights and recommended blue light as the best treatment.
