The Use
of a Bud Freezing Technique to Determine the Hardiness of 20 Grape Genotypes
Table 1:
Effect of freezing temperature exposure under laboratory condition on the primary bud
mortality of 20 grapevine cultivars collected two times in fall 2000 (Frelighsburg,
Quebec, Canada)
The values in the table are
average number of 5 buds for 3 replicates (0= no bud damage, 5= 100%
mortality), data were
arcsin-transformed prior to anova, but are shown as non transformed data
