Mississippi-grown cannabis sativa L.: Preliminary observation on chemical definition of phenotype and variations in tetrahydrocannabinol content versus age, sex, and plant part

Authors


Abstract

Nine strains of Cannabis sativa L. (marijuana) were grown for research by the University of Mississippi. The seeds for these strains were obtained from Iowa, Minnesota, Mexico, Turkey, Italy, France, and Sweden. The cannabinoid content was determined using GLC, and the material was divided into two chemical phenotypes according to cannabinoid content. These phenotype categories are used to differentiate between drug-type and fiber-type Cannabis sativa. In addition, the ( - )-δ9trans-tetrahydrocannabinol content was determined for both male and female plants, various plant parts, and a Turkish variety during various stages in its growth.
