Dominant terpenes refer to the terpenes that are found in the highest concentrations within a particular strain of marijuana. These are the terpenes that are most responsible for the unique aroma and flavor of that strain, as well as its potential effects on the body and mind.

Each strain of marijuana contains a unique combination of terpenes, and the specific dominant terpenes can vary widely depending on the genetics of the plant. For example, some strains are known for their high concentrations of myrcene, which gives them a musky, earthy aroma, while others are high in limonene, which gives them a citrusy aroma. Some strains are known for having high concentrations of pinene, which give them a piney aroma and some for having high linalool content, giving them a lavender aroma.

When it comes to dominant terpenes, it's also important to note that the amount of terpenes present in a strain can also vary depending on factors such as the growing conditions and the methods used to extract and process the plant. However, growers and breeders often focus on breeding plants with certain dominant terpenes because they tend to influence the plant's medical and recreational effects.
