Abstract: | Exogenous spermidine (Spd) and methylglyoxal bis(guanylhydrazone) (MGBG), a putative inhibitor of Spd synthesis, improved somatic embryo formation of Scots pine (Pinus sylvestris L.). The induced maturation due to MGBG and Spd was accompanied by significantly retarded proliferation growth and by reduction in the concentration of free polyamines compared to the control cultures. The action of MGBG revealed that it has a non-specific effect on the whole polyamine metabolism of Scots pine. Furthermore, at certain concentrations it may induce plant differentiation as well. |
