Abstract
Germination is a feature that is characteristic of each individual genotype. If
unfavorable conditions can occur during the seed processing, storage, seed
treatment, transport, germination and emergence, the value of this parameter may
decrease. Therefore the aim of this study was to determine whether the substrate
affects seed germination of two sunflower parental lines treated by various
combinations of pesticides and stored in different storage conditions. The study
involved two substrates for germination - sand and soil. The seed was treated with
fungicides: benomyl, metalaxyl and fludioxonil, insecticides: thiamethoxam and
imidacloprid, control was untreated seed. The seeds were stored in a warehouse and
a cold chamber. Based on the F - test of ANOVA, a significant influence of
substrate on seed germination of both examined lines was determined. Seed
germination in the soil was significantly higher than in sand – at line L-1 for
16.77%, and line L-2 for 6.54%. The L-1 line noted the existence of a significant
effect of storage conditions, the impact of chemical treatment was not significant,
and only interaction the storage conditions x substrate were statistically significant.
Line L-1 also saw the existence of a significant impact of storage conditions, not
significant impact of chemical treatment, and statistically significant only of
interaction storage conditions x substrate
