Abstract
Sweet violet (Viola odorata L.) blooms in continental climate conditions in early spring (March-April) with delicate
flowers of attractive scent because of which it is frequently gathered from its natural habitats. Differences among the populations were established according to their morphological properties of twelve populations from Križevci area. Stated information indicates that the populations gathered from meadow – habitat are shorter and have a smaller diameter than the populations gathered from the habitat in forest, whereas the population from the orchards has the
highest number of leaves and flowers. Correlation analysis shows strong (P<0.01) positive connection of the root mass, leaves mass, number of leaves with the total mass of the plants, as well as connection of the plant mass with the number of flowers.
Chemical analysis established agrochemical soil properties and nutrient concentrations in plants. Correlations between the examined properties of violets and soil properties indicate that the potassium concentration in the roots is in strong (P <0.01) correlation with potassium in the soil, whereas phosphorus concentration in flower is in a considerably strong (P<0.05) positive correlation with the phosphorus in the soil.
