Ultrastructure of Antipodal Cells of Rice (Oryza sativa) after Anthesis, as Related to Nutrient Transport in Embryo Sac
Antipodal cell Lobe-shaped nucleus Oryza sativa Ultrastructure Wall ingrowth
2009/7/27
In a rice embryo sac, there is an antipodal mass located at the opposite side of the micropyle, directly adjoining nucellar cells. Immediately after anthesis, the antipodal cells are characterized by...
Ultrastructure of Antipodal Cells of Rice (Oryza sativa) before Anthesis with Special Reference to Concentric Configuration of Endoplasmic Reticula
Antipodal cell Concentric configuration Endoplasmic reticulum Lobed nucleus Oryza sativa
2009/7/23
Before anthesis, rice antipodal cells are located between nucellar cells and a central cell, and have a large-sized lobed nucleus and many cell-wall ingrowths abutting the nucellar cells. An outstandi...
A Trial of No-tillage Direct Seeding of Rice (Oryza sativa L.) at Early Spring in Cold Climate Region in Japan
Heading Leaf number No-tillage Direct seeding Rice Seeding time
2009/7/16
No-tillage direct seeding of rice (Oryza sativa L.) in early spring was conducted to disperse seeding work and to improve heading time in cold regions. Germinated seeds were seeded every 5 days in 19...
