Programmed cell death in cryo-exposed embryonic axes
A study of silver maple cools embryonic axes to liquid nitrogen temperatures without prior dehydration or cryoprotection treatments and thaws them rapidly.
Stress tolerance of recalcitrant embryonic axes of Quercus
A study finds that four Quercus species adapted to arid and semi-humid climates still produce recalcitrant seeds.
Intracellular ice and cell survival in seeds of Acer
A study of embryonic axes of silver maple, Acer saccharinum, subjected to various drying, cooling and warming treatments, finds that intracellular ice formation is not necessarily lethal.
