Fig. 3From: Standardization of electrolyte leakage data and a novel liquid nitrogen control improve measurements of cold hardiness in woody tissueDamage, as reflected by electrolyte leakage (solid lines) and visual estimates (dashed lines), induced by freezing from − 10 to 80 ℃. Electrolyte leakage is calculated using the Limlogistic approach. Panels represent estimates of damage to particular genotypes. Color-coding indicates speciesBack to article page
