Sowing qualities and productivity of Echinacea purpurea Moench (L) depending on soaking seed in solutions of manganese and zinc

摘要

The results of experiments on presoaking Echinacea purpurea (L) Moench seeds with manganese and zinc are presented. Soaking the seeds ill solutions of MnSO_4 and ZnSO_4 increases the energy of germination by 36% and 33% accordingly. Laboratory germinability increases by 9,5--14,5% and 16,5--17,5%. Field germinability increases by 27,0---40,5%. Optimum concentrations of solutions are 0,05% in MnSO_4 and 0,1% in ZnSO_4. Soaking seed during 12 hours resulted in maximum increase of all investigated parameters.
