Emergence of seeds of decorative species of Salvia L. genius. Popular decorative annual plants as S. splendens, S. coccinea, S. farinacea, S. viridis are grown at the Saratov Botanical Garden`s collection since 2001 year. The dates that are used for the characterization of the quality of seeds are: germination capacity, energy of growth, the speed of emergence, also the strength, swelling and emergence of seeds.
