Effect of iron deficiency and excess on biometric and biochemical parameters indicated in the radish sprouts (Raphanus sativus L. Subvar. radicula pers.) / Wpływ niedoboru i nadmiaru żelaza na parametry biometryczne i biochemiczne oznaczone w kiełkach rzodkiewki (Raphanus sativus L. Subvar. radicula pers.)

The aim of this study was to assess the changes of biometric and biochemical parameters in the radish sprouts (Raphanus sativus L. subvar. radicula Pers.), depending on the content of ions Fe^III+ in the hydroponic culture. Seedlings were grown in Hoagland’s complete hydroponic culture without Fe^III+ ions or with the addition of Fe^III+ ions in an amount of 30 and 300 mg/l. During the experiment, the plants were illuminated by a sodium vapor lamp Son-T-Agro-400 W Philips (40 μE • m²/s PAR at the medium level). After 7 days, some biometric and biochemical measurements were made: shoot and embryonic root length (cm), catalase (CAT) and peroxidase (POX) activity and antioxidant capacity. It was observed that Fe^III+ added to hydroponic culture caused changes in the activity of enzymes and biometric parameters in radish sprouts (Raphanus sativus L. subvar. radicula Pers.).
