Effect of dark incubation on the number of shoots regenerated from sweet orange, grapefruit, and US-942 internode explants.

ANOVA p-values (Prob. > F) for the effect of dark incubation on shoot regeneration in sweet orange, grapefruit, and US-942. One sample t-tests p-values that compared each dark incubation period mean for each citrus type was compared to zero. The number of shoots is presented as the mean ± standard deviation from two experiments that included 9−17 internode explants. Cells with no p-value were all zero (i.e., zero variance) and could not be tested.aUS-942 did not include a three week test.
