Investigation of natural auxins and growth inhibitors were obtained. They show that coleoptiles in 50 y/l. of lAA (phis buffer and sucrose) continue to grow for a long time after they have been put in the solution, whereas the first internodes in the auxin solution stop growing after 18 hours. A short incubation time has the great advantage of minimizing the danger of bacterial contamination in the solutions. T
