| "Nicotiana tabacum trichomes produce two types of diterpenoids – the polycyclic labdanoids and the macrocyclic cembranoids – that together may represent up to 10% of the leaf dry weight in some cultivars and under appropriate culture conditions (Wagner, 1991). The major labdanoids are Z-abienol and labdene-diol, whereas the major cembranoids are α- and β-cembratrien-diol (CBT-diols), together with generally smaller quantities of their respective precursors, α- and β-cembratrien-ol (CBT-ols) (Severson et al., 1984)." \\ | "Nicotiana tabacum trichomes produce two types of diterpenoids – the polycyclic labdanoids and the macrocyclic cembranoids – that together may represent up to 10% of the leaf dry weight in some cultivars and under appropriate culture conditions (Wagner, 1991).
