e0“in C. costatifructa, C. racemosa and C. sessiliflora , when seeds were dehydrated to the optimal water content (0.19, 0.28 and 0.31 g H 2 O g dw −1 , respectively), the percentages of seeds which developed into normal seedlings after LN exposure were 26, 78 and 31% of the desiccation control, respectively.”

Other claims from this paper (10)
- 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. 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 Total germination did not reflect normal seedling development in cryopreservation experiments.
- Observation In abnormal embryos only the shoot apex was destroyed while hypocotyl and radicle were normal.
