COSTEL MOLDOVEANU, VIOLETA VASILACHE, IOAN-MARIAN RISCA BIOLOGICAL EFFECTS OF SOME NEW IMIDAZOLE DERIVATIVES ON SPRUCE (PICEA ABIES) GERMINATION
A new group of diazaheterocyclic salts derived from imidazole were synthesized by addition of acrylonitrile to N-1. The 1-(2-cyanoethyl) imidazole derivatives were quaternized with high-reacting halogen derivatives (halogen esters and halogen amides) and the structure of the obtained compounds were proved by spectral methods (IR, H-NMR, C-NMR, 2DCOSY, HITCOR). For all those compounds the biological effect on the spruce seeds germination were tested. The tests were conducted in controlled temperature room and results showed that the hypocotyls and radicles length varied as a function of concentration and structure of each investigated compound. The investigated compounds exhibited various biological activities, both on the hypocotyls and radicles growth, especially at lower concentrations. Various relationships between structure and biological activity are emphasised.
