Abstract
Echinacea purpurea is a herbaceous plant that is 80-150 cm tall. [1] The roots of the plant penetrate deep into the soil, they have fibrous ramifications, the rhizome is short. Its leaves are wide, lanceolate or elliptic-oblong, and the flowers are conical, have a violet color. Echinacea species are native to North America and in Europe they are cultivated as medicinal or ornamental plants. [17] The research focused on determining the photosynthetic rate in this species, using variants cultivated both in vivo and in vitro. The evaluation was carried out over a period of 49 days. For the variant cultured in vitro, we used the MS culture medium. The experimental results show significant differences between the experimental variants. Also, the processing of the results allowed us to establish the optimal technologies regarding the rate of photosynthesis both in the species cultivated in vitro and in vivo.
