Cannabis glandular-trichome morphology, secretory-disc cell numbers, autofluorescence, metabolite specialization, and evidence that mature stalked floral trichomes develop from sessile-like precursor states.
Visual lesson 07
Stalked trichome development
Follow a floral gland from a sessile-like precursor state through secretory-disc expansion and multicellular stalk development into a mature stalked gland, while distinguishing developmental intermediates from mature leaf sessile trichomes.
