Influence of the compounds TA-14 and TA-12 on the amount of free IAA in the root collars of the oilseed rape cultivars ‘Casino’ and ‘Valesca’ at the end of the cold acclimation period. There were four biological experiments with three replicates in each. Within each cultivar, 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 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.
