Megasporogenesis,microsporogenesis and development of male and female gametophytes in Ceratoides arborescens

摘要

Ceratoides arborescens is an important forage in arid and semi‐arid grassland with high feeding value.It is also good at fixing sands and has strong drought resistance.Previous studies on different Ceratoides arborescens community have found main problems with its community degeneration includeed low seed seting rate and high seed abortion rate.In this study, an effort was made to explore the possible reasons for the failor of seed production with particular interesting in the development of megasporore and microsporore, male and female gametophytes.
