Assessment of soil seed germination of clematis species

The soil germination of clematis species seeds in the Mari El Republic conditions is determined. The greatest germination was observed in seeds of C. mandschurica, and the lowest - in C. serratifolia. Pretreatment of seeds with gibberellic acid did not have a positive effect on their germination. The greatest number of seedlings was obtained in the variant of seed stratification in moss.
