Quality Of Seeds Of Salvia Pratensis From Individual Localities Of Czech Republic Acquired From Both Natural And Controlled Conditions

Quality of Salvia pratensis seeds from 12 natural localities of Czech Republic, which were obtained by both ways collecting in natural sites as well as field cultivation, were studied. 1 000-seeds weight was found between 0.6221 and 2.3455 g (1.3384 +/- 0.38 g in average) and it was statistically significantly influenced by way of seed production as well as by vegetative seasons. Laboratory tests of germination capacity unfortunately brought very low results (0-25%) in both ways of seed production. The positive influence of previous stratification or other pre-seeding treatment to the seed germination can be expected.
