Abstract:

Plant somatic embryogenesis is a common phenomenon and has wide application prospects and potential economic value. Great progress has been made in plant somatic embryogenesis recently, but many problems are still unsolved. Based on the related reports and literature of recent years, the research results on factors affecting of plant somatic embryogenesis were summarized. It is including outer factors, such as plant hormones, light quality, carbon source, osmotic pressure and culture conditions; interior factors, such as genotype and physiological state. This can provide references for the researches on somatic embryo induction.
