- Observation Dasypyrum pollen germinated normally on wheat stigmas and pollen tubes entered embryo sacs.
- Observation Double fertilization with embryo and endosperm occurred in 13 81% of observed ovaries.
- Observation Only embryo formed in 16 19% of observed ovaries.
- Observation Only endosperm formed in 4 76% of observed ovaries.
- Observation Total fertilization rate was 34 76%.
- Observation Total embryo formation rate was 30 00%.
- Observation Endosperm developed more slowly than embryo and was abnormal, absent or later vanished.
- Mechanism Abnormal or missing endosperm made viable mature seed production very difficult.
