| Popis: |
One hundred spearmint (Mentha spicata) plantlets were regenerated from apical shoot segments of ten field- grown donor plants. Although the accumulation of rosmarinic acid and total phenolics in vitro was almost half than in vivo, regenerants demonstrated a tenfold-higher hydrogen peroxide compared to the donor plants. This finding may have been associated with the increased activity of hydroxyphenylpyruvate reductase, a key enzyme of the phenolic biosyn- thetic pathway and the increased production of yet unidentified phenolic compounds in vitro. This process of in vitro cul- ture associated with a reduction of rosmarinic acid and total phenolics and with an increase of the antioxidant capacity in- dicated the possible promotion of in vitro-specific biosynthetic pathways. |
