laboratory experiment was conducted in the laboratory of graduate studies at the Faculty of Science, Hadhramout University during the period from 3/8 - 15/3/2018 to study the effect of different concentrations of gibberellin acid (GA3) and aqueous extract of licorice roots on the percentage and germination rate of the mallow plant, and the length of the radial and plurmule . The seeds were soaked for a whole day in concentrations of gibberellin acid (0, 50, 100 ppm), and the aqueous extract of licorice roots at concentrations (0, 5, 10 g / l). Other seeds were left without soaking. Then all the seeds were sown in Petri dishes and treated with different concentrations of gibberellin acid and licorice roots aqueous extract. The results of the study showed that the germination and plurmule lengths were superior in the studied traits, as the highest germination rate was recorded (2.36 and 2.8 seeds / day) when treated with soaking or direct addition without soaking in succession wheres at a concentration of 10 g / liter of aqueous extract of licorice roots, and where treated with direct addition without soaking with concentrations of 100/10 and 50/5 recarded(2.06-3.02seed s/day) from the mixture of gibberellin acid and the aqueous extract of licorice roots, while the values of the plumule length were superior, as it recorded the best results when treated by soaking. or adding directly without soaking. The results.
