Studies on the Morphine * Content of Papaver somniferum L

Abstract The present paper investigates the variation of the morphine content related to the vegetation stages on Papaver somniferum L, cultivated at Braşov. The study stresses the importance of creating specific poppy cultures for morphine cultures harvested in a stage of immature capsules when the content of morphine and the morphine yield per hectare increase three times. The study also indicates that research in this field led to the creation of a new poppy variety (Safir) with superior morphine content (0.63 g/100 g shells). This variety can be used in seed production for growing cultures used in the production of morphine
