Abstract:
Ehlenfeldt, M. K., Rowland, L. J., Ogden, E. L. and Vinyard, B. T. 2015. LT₂₅, LT₅₀, and LT₇₅ floral bud cold hardiness determinations for a diverse selection of Vaccinium genotypes. Can. J. Plant Sci. 95: 491–494. Freeze-bath cold hardiness results were used to calculate LT₂₅ and LT₇₅ values (temperatures causing 25% and 75% lethality, respectively) for a diverse selection of Vaccinium genotypes which had been previously analyzed for LT₅₀ values. Overall, LT₂₅ and LT₇₅ values paralleled the LT₅₀ values. Across genotypes, the LT₂₅ was approximately 1.7°C (3.1°F) higher than the LT₅₀, and the LT₇₅ approximately 1.6°C (2.9°F) lower than the LT₅₀ for any given date.
