Fig. 1 Study design. Differences in inflorescences between THC-rich and CBD-rich plants without (A, B) and after fertilization with either THC-rich male (strain 319) (C, D) or CBD-rich male (strain 405) (E, F) and their respective induced-male plants (G, H). (I) Representative image of a male donor plant (strain 405). To capture images, the plants were placed on the same white background and photographed individually. (J) Experimental design. Female Cannabis plants of two distinct types, THC- or CBD-rich chemovars, were subjected to fertilization by three different male Cannabis plants: THC- or CBD-rich plants, and an induced-male plant achieved by application of ethylene inhibitor. Female and male plants were incubated together for six to eight weeks. The profile of their secondary metabolites was analyzed by UHPLC/UV and ESI-LC/MS for phytocannabinoids and SHS-GC/MS/MS for terpenoids.
