Isolation and Freezing Tolerances of Mesophyll Cells from Cold-hardened and Nonhardened Winter Rye.

abstract：:Levels of gibberillins (GAs) and of abscisic acid (ABA) in attached leaves of romaine lettuce (Lactuca sativa L.) declined as the leaf became older. The time course of changes in hormone levels, determined in detached lettuce leaves kept in darkness, revealed that a sharp decline in GAs accompanied by a moderate rise ...
