- Observation Coffea arabica seeds were less desiccation sensitive than the three other species.
- Observation At 0.20 g H 2 O g dw −1, 53% of C. arabica seeds germinated after rapid cooling in liquid nitrogen.
- Observation No rapidly cooled C. arabica seeds developed into normal seedlings.
- Observation C. costatifructa normal seedling recovery after liquid nitrogen exposure was 26% of desiccation control.
- Observation C. racemosa normal seedling recovery after liquid nitrogen exposure was 78% of desiccation control.
- Observation C. sessiliflora normal seedling recovery after liquid nitrogen exposure was 31% of desiccation control.
- Observation Normal C. arabica seedlings were recovered only with desiccation and slow precooling to −50°C.
- Observation Precooling at 2°C min −1 allowed 25% of C. arabica seeds to develop into normal seedlings.
- Intervention effect Thawing rate had no effect on C. arabica seed survival.
- Observation In abnormal embryos only the shoot apex was destroyed while hypocotyl and radicle were normal.
