Table 1.
F-values and significance of a three-way ANOVA showing the effects of cultivar (‘Narve Viking’ vs. ‘Titania’), treatment (ambient vs. elevated temperatures), days of forcing and their interactions on the average attainment of each of the four bud stages during forcing of R. nigrum at different times during the winter season. *P < 0.05; **P < 0.01; ***P < 0.001; ns, not significant.
