* DAS: days after sowing. Different Latin letters (a–c) in the same column refer to significant differences between harvest stages for the same plant part (stems or leaves) at p = 0.05. ** Comparison of means of different plant parts (stems and leaves) from the same harvest was performed with Student’s t-test at p = 0.05.
