Other claims from this paper (5)

Intervention effect Perforation produced larger peach embryos.
Intervention effect Perforation did not improve germination over unperforated embryos.
Intervention effect Added vitamins and hormones produced more roots and shoots in plants from unperforated embryos.

Other claims from this paper (4)

Association Embryo water loss correlated with germination rate.
Intervention effect Desiccation with 40 %～50 % water loss yielded about 58 % germination, 9.4 % higher than no desiccation.
Intervention effect Higher relative humidity enhanced embryo germination.
Intervention effect At 70 % relative humidity for 15 d, desiccation raised germination from 33.5 % to 56.2 %.

Other claims from this paper (10)

Association Longer bagging time was associated with slower dehydration under slow dehydration.
Intervention effect Slow dehydration yielded lower relative electrolytic leakage.
Intervention effect Fast dehydration increased MDA content at all three stages.
Intervention effect Fast dehydration increased GR and DHAR activities at all three stages.
Observation AsA content under fast dehydration was too low to detect.
Observation GSH contents were high in fast-dehydrated 20 DAP embryos.
Observation GSH contents were high in slow-dehydrated 32 DAP embryos.
Intervention effect At 24 DAP, the dehydration rates produced no significant difference.
Intervention effect Maize embryos were more tolerant of slow than fast dehydration.
Mechanism The authors attributed maize embryo desiccation tolerance chiefly to GSH.
