Other claims from this paper (16)
- Observation Cucumber pollen germinating power appeared before anther dehiscence.
- Observation Egg-plant pollen germinating power appeared after anther dehiscence.
- Observation Cucumber pollen viability reached its maximum at or immediately after anther dehiscence.
- Intervention effect Cucumber pollen viability varied when temperature treatment began 39 hours before anthesis.
- Intervention effect High temperature shortened cucumber pollen longevity.
- Intervention effect Low temperature prolonged cucumber pollen longevity.
- Observation Cucumber pollen viability was highest in male flowers at 20-25°C.
- Association Egg plant anther dehiscence and anthesis varied with temperature.
- Observation Egg plant anther dehiscence generally preceded anthesis.
- Observation Egg plant pollen germinating power rose immediately after anther dehiscence.
- Intervention effect High temperature for one day shortened egg plant pollen longevity more than low temperature.
- Observation Egg plant anthers scattering abundant pollen grains were at an advanced maturation stage.
- Intervention effect Prior temperature influenced egg plant pollen maturation after transfer to 20°C.
- Association Egg plant pollen viability varied with temperature from anther dehiscence.
- Association Egg plant pollen longevity varied with temperature from anther dehiscence.
- Recommendation The authors estimated approximately 20°C as appropriate for egg plant pollen maturation.
