Sažetak
The effect of hydrroxyquinoline halogenated derivates as fungicides and their influence on seed germination from the biological and biochemical aspects was investigated. Maize seed naturally infected with Fusarirum spp. fungi (F. graminearum, F. monilifrome) and saprophytic fungi (Pencilium spp., Aspergillus spp., Trichothecium roseum, Rhizopus nigricans, Alternaria spp., Cladosporium herbarium and Acremoniela atra) was treated immediately after harvesting with hydroxyquinoline halogenated derivates (J, Cl, Br) and TMTD (Radotiram) in a 200 g/mtc dose. The seed was stored for five months. The fungicidal effect, tested in March, in the period before sowing, has shown that hydroxyquinoline chlor derivates were the most efficient, and that all halogenated derivates were significantly better than TMTD, investigated in comparison. Hydroxyquinoline halogenated derivates investigated at storage and sowing time did not influence seed germination, while in comparison with untreated, seed the germination of treated seed was significantly better. Finally a stimulative influence of hydroxyquinoline chlor derivates on the ribonuceleic acid synthesis (RNK) in germs in the first hours and days of seed germination was established as one of the indicators of the germs vital energy during the initial and the most delicate development period.
