Influence of growth regulators and elicitors on cell growth and α-tocopherol and pigment productions in cell cultures of Carthamus tinctorius L.

The present study examined the effects of plant growth hormones, incubation period, biotic (Trametes versicolor, Mucor sp., Penicillium notatum, Rhizopus stolonifer, and Fusarium oxysporum) and abiotic (NaCl, MgSO(4), FeSO(4), ZnSO(4), and FeCl(3)) elicitors on cell growth and α-tocopherol and pigment (red and yellow) productions in Carthamus tinctorius cell cultures. The cell growth and α-tocopherol and pigment contents improved significantly on Murashige and Skoog (MS) liquid medium containing 50.
