WU Cheng-hou Redai yaredai zhiwu xuebao 2004
Other claims from this paper (7)
- Observation Ovule primordium differentiation began at low temperature 50 days after pollination.
- Observation Megasporogenesis appeared at low temperature 60 days after pollination.
- Observation At normal temperature, megagametophyte formation and double fertilization were complete by day 70.
- Observation At low temperature, megasporogenesis was unfinished at day 70.
- Observation Low temperature advanced nucellar cell degeneration.
- Mechanism The embryo sac wall around the megasporocyte thickened following early nucellar cell degeneration.
- Observation The embryo sac developed only into functional megaspores, without a mature embryo sac.
