The primary supraspecific taxonomic category that groups phylogenetically closely related species.
Glossary of terms
A reference section with categories and short explanations.
Vegetative bud
Термины кактусовода
That produces a vegetative shoot after unfolding.
Savannas
Термины кактусовода
Predominantly flat areas with a predominance of red-brown soils. Herbaceous cover predominates in combination with individual trees or groups of trees.
Self-pollination
Термины кактусовода
Pollination in which the stigma is pollinated by the pollen of the same flower or of another flower of the same plant, or the ability of pollen to fertilize the egg cells of its own flower; the highest degree of self-pollination is cleisto…
Matting
Термины кактусовода
Entangling, sticking together, clumping of the pubescence of areoles under the action of water that has fallen on them.
Free planting
Термины кактусовода
Planting of plants into a volume of soil that allows the roots to grow unobstructed in all directions.
Rootstock segments
Термины кактусовода
Parts of a long cactus shoot, each of which is used as a rootstock without being rooted.
Selection
Термины кактусовода
Selection and propagation of individuals possessing some desirable trait.
Family
Термины кактусовода
A taxonomic category that groups related genera that have a common origin.
Seed coat
Термины кактусовода
Protective covering, testa.
Seed
Термины кактусовода
Embryonic stage of seed plants.
Cotyledons
Термины кактусовода
Modified first leaves of the embryos of dicotyledonous plants, developing in the seed and usually serving after germination as storage organs for nutrients.
Seedlings
Термины кактусовода
Young plants that have developed from seeds.
Sessile flowers
Термины кактусовода
Without or with a very short pedicel.
Syntype
Термины кактусовода
One of two or more specimens that served as the basis for the original description when the author did not designate any particular specimen as the holotype.
Plant systematics
Термины кактусовода
A branch of botany that develops a natural classification of plants based on the study of the origins and causes of formation of particular taxonomic units, including analysis of their historical development and the establishment of stable…
Scarification
Термины кактусовода
Damage to the seed testa (seed coat) to increase their ability to germinate. It is carried out mechanically or by treatment with concentrated sulfuric acid followed by thorough rinsing with water.
Sclerophytes
Термины кактусовода
Plants adapted to living in dry conditions without storing large amounts of water.
Absorbing root hairs
Термины кактусовода
Root hairs that form on branches of the root system when they are wetted with water, which helps to increase absorptive capacity. They die off during prolonged soil dryness.
Sporadic
Термины кактусовода
(From Greek sporadikos - single) - appearing from time to time.
Method of propagation
Термины кактусовода
A method of increasing the size of a population. In the cultivation of cacti, two methods of propagation are distinguished: generative propagation (seed propagation) and vegetative propagation: cuttings, offsets, and micropropagation.
Dormant buds
Термины кактусовода
Formed in autumn but developing in spring.
Stagnation
Термины кактусовода
(From Latin stagnum - standing water) a state of arrested plant growth, the transition from active life processes to forced dormancy, a temporary cessation of growth under unfavorable conditions.
Stem mealybug
Термины кактусовода
An insect pest that parasitizes the stems of succulents.
Soil sterilization
Термины кактусовода
Complete destruction of microorganisms, both harmful and beneficial, by steaming the soil in an autoclave or by other methods, bringing the temperature to the boiling point of water.
Seed stimulation
Термины кактусовода
Method of activating the vital activity of seed cells
Seed stratification
Термины кактусовода
Artificial partial or complete breaking of seed dormancy by exposing seeds to low (down to 2 °C) temperatures in moist peat, sand, perlite and other materials, or by brief freezing after soaking them in water.
Substrate
Термины кактусовода
Natural or artificially created multi-component soil mixture for growing plants. The composition of the substrate largely depends on the requirements of the species for which it is intended.
Mineral substrate
Термины кактусовода
Substrate that does not contain organic components (organic matter).
Clay loam
Термины кактусовода
Soil containing clay and sand with a predominance of clay.
Succulent
Термины кактусовода
(From Latin succulentus — succulent, fleshy) — a group of species of perennial xerophytic plants adapted to existence in arid conditions thanks to the ability to store water in a highly developed specialized tissue — water-storing parenchy…
Schizocotyly
Термины кактусовода
"False pleiocotyly" - the phenomenon of the original cotyledons splitting into two, less often three, lobes or segments. At the same time, as a rule, the pattern of vascular connections characteristic of a dicotyledonous embryo can be trac…
Sciarids
Термины кактусовода
Pest insects whose larvae primarily damage the roots of seedlings.
Taxon
Термины кактусовода
An individual which, together with others related to it by varying degrees of similarity in properties and characters, makes it possible to distinguish it and its like into a particular taxonomic category; the set of characters and propert…
Taxonomist
Термины кактусовода
A specialist systematist engaged in taxonomic matters.
Taxonomic unit
Термины кактусовода
Any classificatory unit in systematics (form, genus, species, etc.).
Taxonomy
Термины кактусовода
The theory of classification and systematization of plants, often regarded as synonymous with systematics, although systematics is a broader concept, and taxonomy, as a branch of systematics, deals with the methods and rules of plant class…
Tektotype
Термины кактусовода
Fragment of the type taken for microscopic studies.
Temperature regime
Термины кактусовода
Maintaining temperature within the parameters optimal for plant development.
