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.
