[The effects of barbiturates on the embryonic growth of seedling of lepidium sativum L (author's transl)].
The influence of some important barbiturates on the capacity to stimulate or to stop the growth of seedling of Lepidium sativum L. was tested and the results statistically evaluated. Phenobarbital, cyclobarbital and pentobarbitial show a significant stimulating effect on growth between 10(-2) and 10(-4) moles/l. All barbiturates in concentrations over 10(-3)M act strongly inhibiting. The average inhibitory concentrations (ID50) show a clear dependence on biological properties, in the first place the partition coefficient.
