Types of Trichomes Explained

Types of Trichomes Explained Professor DeBacco Trichomes Trichomes- a small hair or other outgrowth from the epidermis of a plant, typically unicellular and glandular. These structures are the site of cannabinoid, terpene and flavonoid production. These are found on more than just cannabis plants as trepens function as a natural plant defense mechanism. Glandular Trichomes Glandular trichomes produce and store large amounts of cannabis resin which are found in high quantities on female flowers, but are also found on leaves and on stems of younger plants. Glandular trichomes can occur as small bulbous trichomes with one-cell stalks, sessile glands which are attached directly by the base without a stalk, or multicellular stalked glandular trichomes with long multicellular stalks on the bracteoles surrounding the pistillate flowers. However three a common glandular trichomes to cannabis… Bulbous trichomes Capitate sessile trichomes Capitate-stalked trichomes Bulbous Trichomes Bulbous trichomes are found throughout the plant but do not produce or contain cannabinoid or terpenes Very small at 15-30 microns in size. Capitate Sessile Trichomes Capitate-sessile trichomes that have a globular shaped head and are the most common as they are found on the stems, leaves and bracts. While these trichomes do produce cannabinoids, the levels produced are much lower than the capitate-stalked trichomes discussed next;-) These are mid-sized measuring from 25-100 microns across Capitate-Stalked Trichomes Capitate-stalked trichomes are the primary source of the cannabinoids, terpenes, and other plants oils found in the cannabis plant that develop only after flower formation. If you look at the bracts of the flower and small tiny mushrooms that measure from 150-500 microns tall. Non-Glandular Trichomes Non-glandular trichomes are hair-like extensions resembling leaf hairs, with a slender pointed apex. They protect the plant from its environment, mainly through physical means (e.g., restricting access to animals and insects, preventing water losses or light degradation, and fungal infection). It is characteristic of cannabis to find non-glandular trichomes on both the top and bottom of leaves. Two Main Non-Glandular Trichomes Cystolithic trichomes Non-cystolithic trichomes Cystolithic Trichomes Cystolithic trichomes have a characteristic bear claw shape and may have calcium cystoliths resembling knobs visible at their bases. They are found on the upper surface of the leaves and range from 150 to 220 microns in height. Frequently, the trichome is broken and the knob freed. Non-Cystolithic Trichomes Non-cystolithic trichomes are found most often on the lower side of the leaves, bracts, and bracteoles and tend to be fine and slender in shape.
