Abstract

The objective of this study was to investigate the effect of controlled release fertilizer (CRF) on the activity of three antioxidant enzymes in cucumber transplants. Three treatments - a 125 mg N/l and a 250 mg N/l basal application level, and a 125 mg N/l level complemented by four sidedressings to 250 mg N/l - were carried out either using a CRF, or a readily available fertilizer (RAF). Activity of guaiacol peroxidase, ascorbate peroxidase and glutathione reductase were measured from the roots and the youngest leaves three times during the raising period. Salt levels of the pot mixtures were higher in the RAF treatments than in their corresponding CRF treatments during the first half of the experiment. The activity of ascorbate peroxidase showed the strongest correlation with the salt level, especially at the time of the first measurement. According to the dry weight data the sometimes two-fold differences in the salt level did not have a growth reducing stress effect on cucumber transplants.
