Status of the IAA fund in the root collars of the oilseed rape cultivars ‘Casino’ (A) and ‘Valesca’ (B) during the early period of cold acclimation. There were four biological experiments with three replicates in each. Different lowercase letters indicate significant differences in the mean percentage of free IAA between the two oilseed rape cultivars. Different uppercase letters indicate significant differences in the mean percentage of IAA conjugates between 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.
