تاﺛﻴﺮ ﻣﺘﻴﻞ ﺟﺎﺳﻤﻮﻧﺎت و ﻋﺼﺎره ﻗﺎرچ Fusarium graminearum ﺑﺮ رﺷﺪ رﻳﺸﻪﻫﺎی ﻣﻮﻳﻴﻦLinum austriacum

Linum austriacum is an important medicinal plant which contains pharmaceutical compounds such as an arylnaphthalene lignin Justidin B with anticancer activity. Hairy roots are valuable biotechnological tool for the production of pharmaceutically important plant secondary metabolites. The accumulation of hairy root biomass and production of secondary metabolites can optimize by elicitation. In this study, the effects of different concentrations two elicitors methyl jasmonate (MeJA) and Fusarium graminearum extract (FE) on hairy root growth of L. austriacum were investigated. There was a significant difference between different concentrations of MeJA and FE on growth of hairy roots. The highest concentration of MeJA (200 μM) at 10 days post-treatment caused significant effect on hairy root biomass with a reduction of 30% in root growth, however, the highest concentration of FE (1.5%) did not significantly affect the growth of root.
