There is a need for large amounts of plant tissue to be grown under controlled environments, and plant tissue culture is one unique way to yield this tissue. The purposes of this study were to determine: 1) the optimal concentrations (μM)/ratios of auxin:cytokinin in media and;2) the optimal mineral salts formulation for callus induction and callus growth in select hemp cultivars. To find the optimal concentration/ratios, 16 different combinations of auxin:cytokinin and three different mineral salts formulations were evaluated. The three mineral salts formulations tested were MS salts, MB5D1K and an MTSU formulation. The top performing hormone formulations were determined to be equal concentrations (1:1, 2:2, 3:3 μM) of auxin and cytokinin. The top performing media hormone formulations for callus induction were determined to be 2:1, 2:2, 2:3, and 3:2 μM (auxin:cytokinin). The optimal mineral salts formulation was determined to be MD5D1K. Therefore, the overall optimal media formulation for hemp callus production would be MB5D1K salts with the concentration/ratio of 2:2 μM (auxin:cytokinin).展开更多

Vegetative cuttings (clones) of C. sativa are the preferred propagation technique to be the most effective in retaining the same genetic information and reducing hybridization and mutations. The objective of this project was to assess cannabinoid profile concentrations of successively cloned generations of 5 varieties: Cherry, Cherry Blossom, Cherry × Workhorse, Sour Space Candy, and The Wife. This research project focused on the idea that every cloned plant contains the exact same genetic information and, therefore, should have the same metabolic profile of cannabinoids through all the successive generations grown, which is shown to be true. Plants were cloned for multiple generations using stem cuttings and a commercial cloner. As plants matured, they were set in environmental conditions to stimulate flowering and buds were harvested and analyzed for cannabinoid contents using HPLC. Several generations of each variety were successfully cloned. As many as 17 different cannabinoids were analyzed and the results of this study show that there is not a significant difference in cannabinoids over successive generations, showing no major trends.展开更多
