Abstract
Bromegrass cell suspension cultures, varying in frost hardiness, were immersed ìn distilled water and electrical conductivity of the bathing solutions was measured at various intervals after immersion. It was found that tissue frost-hardened by maintenance at 2‡C leaked more electrolytes than the relatively frost-sensitive tissue grown at 20‡C, but that tissue frost-hardened by abscisic add treatment displayed decreased leakage, despite comparable levels of frost-hardiness having been achieved. It is concluded, in contrast with the conclusion of a previous report, that changes in membrane permeability to electrolytes may not be directly related to the capacity of cells to tolerate freezing stress.
