A reference section with categories and short explanations.
Floral tube
Cactus grower terms
(Better: pedicel) - the part of a flower bearing the perianth, often pubescent or covered with scales.
Flower
Cactus grower terms
A flower is a modified, shortened shoot [generative], adapted for the formation of micro- and megaspores, gametes, and for cross-pollination. (Khrzhanovsky V., Kraevsky I., Ponomarenko S. Botany, 1975).
Flower buds
Cactus grower terms
Buds that contain only flower primordia. In this state they can remain on the stem for a long time and begin to develop only under optimal conditions and at the appropriate time of year, often associated with genetic memory.
Flowers
Cactus grower terms
These are reproductive organs whose evolutionary origin is unclear. Flowers are usually simply referred to as the organs of sexual reproduction. (Green N., Stout W., Taylor D., Biology, 1996).
Forced dormancy
Cactus grower terms
Stagnation.
Forcing of plants
Cactus grower terms
Various methods of accelerating plant development or of bringing them out of dormancy into an active phase of growth.
Free planting
Cactus grower terms
Planting of plants into a volume of soil that allows the roots to grow unobstructed in all directions.
Fruiting buds
Cactus grower terms
Buds that produce flowers after opening.
Fungicides
Cactus grower terms

Generative organs of the plant
Cactus grower terms
(From lam. genero - I give birth, I produce) perform the function of sexual reproduction, otherwise - reproductive organs; in angiosperms (flowering plants) they are represented by female and male gametophytes. At present this concept is o…
Generative reproduction (sexual)
Cactus grower terms
Reproduction by means of seeds, seed reproduction of plants by sexual means as a result of cross-pollination by the transfer of pollen from the stamens of one flower to the stigma of a flower of another plant of the same species.
Generative shoot
Cactus grower terms
Shoot bearing reproductive organs.
Generative zone
Cactus grower terms
Part of the stem bearing the organs of sexual reproduction.
Genesis
Cactus grower terms

Genetic memory
Cactus grower terms
The ability of plants transferred to a different habitat to retain, from generation to generation, certain characteristics of the annual development cycles of their ancestors in their homeland.
Genetics
Cactus grower terms
The science of heredity and variation of organisms.
Genotype
Cactus grower terms
(From Greek genos - kin, origin and typos - imprint) the hereditary basis of an organism, the totality of all hereditary information (genes) of a given organism, determining the norm of its reaction under all possible environmental conditi…

Cactus grower terms
The primary supraspecific taxonomic category that groups phylogenetically closely related species.
Geophytes
Cactus grower terms
A life form of certain herbaceous plants whose renewal buds are located in the soil.

Germination
Cactus grower terms
A set of technological measures that facilitate the germination of seeds during sowing.
Glochids
Cactus grower terms
Easily detached, unicellular hairs bearing saw-like barbs, very sharp and stiff, located in the areoles of Opuntia.
Graft fixation
Cactus grower terms
Securing the scion to the rootstock to ensure their union.
Grafting
Cactus grower terms
A horticultural technique that involves joining the scion and the rootstock, resulting in accelerated growth of the scion or simplifying its care.
Growing point
Cactus grower terms
The tip of the main organ (stem, root), composed of formative tissue represented by a group of meristematic cells.
Growth dynamics
Cactus grower terms
Differences in the rate of plant growth associated with natural factors (temperature, amount of light energy and precipitation), as well as with aspects of maintenance under enclosed growing conditions (frequency of watering, addition of f…
