Other claims from this paper (8)
- Observation Winter cultivar Fiona anther homogenate supernatant had osmotic pressure equivalent to 17% sucrose.
- Intervention effect The highest sucrose concentration gave Fiona the highest microspore survival after 16 days.
- Intervention effect Spring cultivars had much higher microspore survival at 16% than 8% sucrose.
- Intervention effect Spring cultivars had much higher embryo induction at 16% than 8% sucrose.
- Intervention effect Higher sucrose reduced variation in response among spring cultivars.
- Observation The benefit of 16% sucrose persisted across donor plant growth environments and pollen stages.
- Observation Macroscopic embryos emerged only from anthers grown at 8% sucrose.
- Recommendation The authors suggest transferring anthers from high to normal sucrose concentration during culture.
