The amount of selenium determined in safflower from the first harvest was as much as 25 times higher compared to the young nigella shoots from the first harvest. Interestingly, the opposite relationships were observed for the content of another micronutrient, i.e., lithium. Its amount in the young nigella shoots from the first harvest was even 41 times higher (3.085 mg/100 g DW) compared to that found in safflower from the first harvest (0.076 mg/100 g DW).
