Some morphological characters of the plants connected with reproduction were analysed at various phases and compared in two successive seasons. The following characters were estimated at the individual level: number of ovules and primary pollen grains per plant, pollen viability, pollen-ovule ratio, number of achens per plant and their germinability, seed-ovule ratio. Most of data characteristics of reproductive strategy were calculated according to the formulae proposed by Urbanska. Apomictic cytotypes have both a significantly lower pollen viability and seed-ovule ratio (the lowest values in triploids) than sexual diploids.
