Induction of Tetraploids from Petiole Explants through Colchicine Treatments in Echinacea purpurea L.
Petiole explants were obtained from in vitro grown diploid (2x = 22) Echinacea purpurea plantlets. Shoots were regenerated by culturing the explants on MS basal medium containing 0.3 mg/L benzyladenine (BA), 0.01 mg/L naphthaleneacetic acid (NAA) and four concentrations (30, 60, 120, and 240 mg/L) of colchicine for 30 days, or 120 mg/L of colchicine for various durations (7, 14, 21, and 28 days...
متن کاملA C-banded karyotype of mitotic chromosomes in diploid purple coneflower (Echinacea purpurea L.)
BACKGROUND Aneuploid ermpglasm is an important resource for genetic studies and identification of individual chromosomes in the cells of the aneuploid is an important step. The karyotype has already been established for purple coneflower (Echinacea purpurea L.), but due to the high similarity in the morphology of several pairs of chromosomes in this species, it cannot be used to identify indivi...

متن کاملApplication of response surface methodology for optimization of purple coneflower plant (Echinacea purpurea)
Echinacea purpurea belongs to the family of Asteraceae which has different medicinal properties. The main goal of current research was optimization of callus induction and biomass production by using Response Surface Method (RSM). For this purpose, root and leaf explants were cultured in the ½ MS medium supplemented with different concentrations (0, 1 and 2 mg/L) of Kin either alone or with 2,4...
