Glossary of Terms(Incomplete)
A:- ABA - Abscisic acid - plant hormone, a major factor is mediating the adaptation of the plant to stress.
- Abaxial - The abaxial surface of a leaf is the underside or side facing away from the stem.
- Accessory Cannabinoids - Cannabinoids (CBC, CBD, CBN) which probably interact with the primary cannabinoids (THC) to alter their effect.
- Accessory Pigment - Pigment other then the primary pigment (clorophll) which collects solar energy.
- Acclimatize- Become adapted to new enviromental conditions.
- Adaxial - Oriented toward the shoot meristem, the upper surface of the leaf.
- Adnate - United to a part or organ of a different kind, as stamens attached to petals.
- Adventitious Roots - A root that arises from a stem, rather than from the primary root.
- Alternate Phyllotaxy - Leaves appear singly in a loose staggered spiral along the stem, non opposite.
- Aneuploid - An organism with an unbalanced set of chromosomes (i.e., 2n-1 or 2n+1).
- Anthesis - The period during which a flower is fully open and functional.
- Anthocyanin Pigment - Accessory pigment. Anthocyanin pigments are responsible for the red, purple, and blue colors of many fruits, vegetables, cereal grains, and flowers.
- Anticlinal - Cell divisions that take place in a plane that is perpendicular to the surface of the next surface of the organ.
- Apical - Tip or top position, for example the apex of the stem has an actively growing apical bud.
- Arborescent - Tree like.
- Asexual Propagation - Vegetative reproduction by cloning, producing offspring with the genotype identical to that of the single parent.
- Auxins - A class of plant hormones.
B:- Back-crossing - Crossing of an offspring with one of the parents to reinforce a parental trait.
- Bract - Small reduced leaflet in Cannabis that appears below a pair of calyxes.
- Bulbous Trichome - Small stalkless glandular trichome. Bulbous, a word worth repeating.
C:- Callus -Undifferentiated group of cells, which under proper conditions will differentiate to produce roots and stems.
- Calyx - Five-part carpel structure of the staminate flower; or, five-part fused tubular sheath surrounding the ovule and pistils of the pistillate flower.
- Cambium - Layer of cells which divides and differentiates into xylem and phloem.
- Cannabaceae - Family to which only Cannabis (marijuana) and Humulus (hops) belong.
- Cannabinoid - Cyclic hydrocarbon which is found only in Cannabis, derived from a terpene molecule and a cyclic acid molecule.
- Cannabinoid Profile - Ratio and levels of major cannabinoids found in a particular individual or strain of Cannabis.
- Cannabis - Genus name of marijuana or hemp
- Capitate - Terminating in a bulbous swollen area.
- Capitate-sessile Trichome - Resin-producing glandular trichome without a (visible) stalk which may develop into a a capitate-stalked trichome.
- Capitate-stalked Trichome - Resin-producing glandular trichome with a stalk.
- Captan - A commercial fungicide.
- Carotenoid Pigment - An accessory pigment, usually yellow, orange, red or brown.
- Carrier - A plant infected with a virus but exhibiting no symptoms due to its high resistance.
- CBC - Cannabichromene.
- CBD - Cannabidiol.
- CBDV - Cannabidiverol.
- CBG - Cannabigerol.
- CBN - Cannabinol.
- CBNV - Cannabiverol.
- CBT - Cannabitriol.
- CCY - Cannabicyclol.
- Cellular Cloning - Asexual propagation of new individuals from small groups of single cells, as distinct from layers or cuttings.
- Centripetally - Outward from the center.
- Cerebral - Pertaining to the mind or head, mental.
- Chemotype - A specific chemical phenotype which in Cannabis is usually based on ratios of cannabinoids.
- Chemovars - Cultivars or races of Cannabis defined by their particular chemical composition.
- Chlorosis - Yellowing of plant tissues resulting from the breakdown of chlorophyll.
- Chromosome - Strand of DNA-protein complex in the nucleus of a cell along which genes are found.
- Clone - An asexually produced offspring preserving parental genotype
- Colchicine - A natural but dangerous alkaloid used to induce polyploid mutations in plants.
- Cotyledons - Seed leaves which are present in the embryo and first appear upon germination.
- Critical Daylength - Maximum daylength which will induce flowering.
- Crossing - Mating of two organisms.
- Crossing Over - Switching entire pieces of genetic material between two chromosomes.
- Crystaloids - Crystalline globules in the cytoplasm.
- Cultivar - A variety of plant found only in commercial cultivation.
- Cuticle - Covering of plant wax on the surface of the epidermis.
- Cuttage - Rooting a piece of stem (cutting) removed from a parent plant.
- Cytokinins - A class of plant growth substances (hormones).
