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 The highest sucrose concentration gave Fiona the greatest number of anthers with induced embryos after 42 days.
Intervention effect Spring cultivars had much higher microspore survival 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.
