Cannabis flowers with the most mushroom-shaped hairs pack the biggest cannabinoid and fragrance punch, according to new research from the University of British Columbia.
While the cannabis leaf is iconic, it’s the chemicals produced by the tiny, frostlike hairs on cannabis flowers that give the plant its psychoactive and medicinal properties and distinctive smell.
In a study published in The Plant Journal, UBC researchers have revealed the unique structures and chemical outputs of the different types of hairs, or glandular trichomes, for the first time.
Their findings confirm what many cannabis connoisseurs have long suspected: that the largest, mushroom-shaped stalked glandular trichomes are the richest source of THC- and CBD-forming metabolites and fragrance-giving terpenes.
“Despite its high economic value, our understanding of the biology of the cannabis plant is still in its infancy due to restricted legal access,” said co-lead author Teagen Quilichini, a postdoctoral fellow at UBC botany and Anandia Laboratories Inc. “Trichomes are the
