Magnesium (Mg) leaf fertilization considerably increased plant height, and with it the assimilation surface, in every tested taxon. It also affected the number of flowers and total seed yield favourably. At the same time, individual seed yield decreased with lower composite flower size. Spineless taxons with whole-edged leaves had higher seed yield (80-119 g/plant) than spiny types (66-105 g/plant). Their linoleic acid content was, however, inferior to that of the spiny types. The linoleic acid content of the taxons varied between 69 and 74% and even increased in leaf fertilization. Oleic acid showed opposite tendencies, that is, more linoleic acid was found at lower oleic acid contents.
