Figure 7. Different types of trichomes on Cannabis sativahemp varieties.
Trichomes can be found on the majority of female Cannabis plant
epidermises of the cultivars ‘Finola’ (a-f) and ‘Felina 32’ (g, h).
Vegetative leaves (a) have mainly non-glandular hair-like trichomes (b).
Subtending (“sugar”) leaves within an inflorescence (c) do have both,
non-glandular trichomes as well as glandular trichomes (d). The
perigonal bract of a female ‘Finola’ flower (e) is covered in glandular
stalked trichomes (f), while the majority of trichomes found on the
bract of ‘Felina 32’ flowers (g) are non-glandular and sessile trichomes
(h).
White arrows: non-glandular trichomes; white arrowheads: sessile
trichomes; red arrowheads: stalked trichomes.
