The Use of Nanostructured Gibberellic Acid to Optimize the Cultivation of Echinacea purpurea (L.) Moench In Vitro

The sterilization process of plant explants of E. purpurea was optimized when introduced into an In Vitro culture, the most effective sterilizers, their exposure time and concentration were selected. An approach to increase the yield of plant explants seedlings from Echinacea purpurea (L.) Moench seeds is proposed. During the study an effective action time of 1 hour and a concentration of 1% nanocapsulated gibberellic acid were selected for more successful seed germination and cultivation of E. purpurea in vitro . This mode is at the same time the most economical both in terms of exposure time and in the minimum consumption of the active substance. The most optimal media compositions were determined, both for microclonal propagation and for the formation of E. purpurea callus tissue in in vitro culture.
