This investigation was carried out to improve the germination percentage and alkaloid 1 production in M seeds (irradiated seeds with 50, 80, 110 and 150 Gy) of Atropa belladonna L. by using and different concentrations of gibberellic acid (20,40,60,80,100 and 120 ppm). There was an increase in seed germination percentage by increasing gamma-ray doses until 150 Gy which gave 3 decrease in seed g...
