Somatic embryogenesis and plant regeneration from immature inflorescences of Pennisetum purpureum Schumach (Napier grass)

摘要

Pennisetum purpureum Schum.( Napier or elephant grass) is a major fodder and energy crop in tropic and subtropical region.Napier grass.N51"was introduced to China from US in 1985. Although the formation of somatic embryos and plants from inflorescence segments of napier grass was reported (Wang and INDRA,1982),there is a number of difficult problem because of different genotype of each species responding optimally in vitro.This paper describes extensive somatic embryogenesis and plant regeneration from cultured segments of immature inflorescence of napier grass.N51",which does not usually set seeds in nature and is principally propagated vegetatively.It will make a possibility of industrial tube seedling production and breed by biotechnology.
