Hydroponic Culture of Triticum aestivum as a Model System to Evaluate the Biological Effects of Fusariosis and Fungicides

Abstract

The research of the potential of hydroponic culture Triticum aestivum as a model system for the study of the biological effect of fungicides included determination of the content of peroxidation products of lipids (malondialdehyde) and proteins (carbonylated proteins), free proline in roots, and border cells in the root apex of 2-day-old seedlings infected with Fusarium graminearum. In the infected seedlings roots content of proline, carbonylated proteins and border cells was 1.4; 8.0 and 3.0 times, respectively, higher than in roots of non-infected seedlings. Triazole fungicide tebuconazole in the studied concentrations (0.01, 0.10 and 1.00 µg/ml medium) caused a dose-dependent decrease in the number of border cells in the root apex of infected seedlings. The results allow to positively evaluate hydroponic culture Triticum aestivum as a model system for studying of the biological effects of the fungicides (in particular, their phytotoxicity) and fusariosis.
