Influence of the compounds TA-14 and TA-12 on the amount of IAA in the terminal buds (A) and root collars (B) of the oilseed rape cultivars ‘Casino’ and ‘Valesca’ during the early period of cold acclimation. There were four biological experiments with three replicates in each. Within each cultivar in the same organ, different lowercase letters indicate significant differences in the mean amount of IAA between the control and two different treatments. Different uppercase letters indicate significant differences in the mean amount of IAA in the same organ between the two oilseed rape cultivars. Bars are the means ± SD with different letters and are significantly different at p < 0.05 according to the Duncan test.
