Abstract
Tomato plants grown under controlled greenhouse conditions were submitted to constant fertilization of macro‐ and micronutrients. The aim of the experiment was to determine both the effect of different genotypes of tomato plants on the foliar content of Fe as well as the behaviour of some of its physiological indicators. For the 12 tomato genotypes used, the following parameters were analysed: total Fe, HCl‐extractable Fe, peroxidase (POD), catalase (CAT), chlorophyll a (Chl a), chlorophyll b (Chl b) and carotenes. The results showed a strong influence of genotype on the foliar content of Fe, both in its total and HCl‐extractable form. With regard to the POD and CAT activities, as physiological indicators of Fe, the POD activity proved predominant. The activities of the chlorophyll and carotene pigments provided good indicators of the Fe level in the different genotypes.
