Cactus grower terms
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.
Cactus grower terms
The community of microorganisms present in the soil.
Cactus grower terms
A method of vegetative propagation by culturing isolated tissues or cells in artificial media.
Cactus grower terms
(From Greek mikros - small, pyle - entrance, opening) - a narrow channel in the integuments of the ovule of seed plants, through which the pollen tube penetrates to the nucellus, the pollen entry.
Cactus grower terms
Resemblance of particular plant organs to various objects of the surrounding environment.
Cactus grower terms
Inorganic compounds of macro- and microelements that are introduced to or present in the soil, mostly phosphate, sulfate and carbonate salts of potassium, calcium, sodium and magnesium.
Cactus grower terms
Substrate that does not contain organic components (organic matter).
Cactus grower terms
Changes in an organism's phenotype not associated with changes in its genotype.
Cactus grower terms
Cultivation of a single plant species.
Cactus grower terms
A genus represented by only one species.
Cactus grower terms
A growth anomaly that leads to the formation of peculiar ("deformed") specimens consisting of many unevenly growing shoots.
Cactus grower terms
(From Greek morphe - kind, form) - a group of phenotypes within a species or population that is markedly distinct in appearance. Species and populations that have different morphs are called polymorphic.
Cactus grower terms
Characteristic of any plant organ that allows it to be distinguished from others and assigned to a particular group in classification.
Cactus grower terms
The term, widely used among collectors, designates mature fruiting plants, or their "stumps", that serve as a source for obtaining cuttings and daughter shoots from which new full-fledged plants are obtained for their subsequent rooting or…
Cactus grower terms
(From mutation and Greek genes - generating) - a physical or chemical factor that increases the frequency of occurrence of mutations.
Cactus grower terms
An abrupt, discontinuous, heritable and stable change affecting the characteristics of plants.
Cactus grower terms
Microorganisms possessing characteristics of both bacteria and viruses. They are causal agents of various diseases of plants and animals, including humans.
Cactus grower terms
Plants that originated and, in the course of evolution, have continued to inhabit the locality to the present time.
Cactus grower terms
The ability of plants to adapt and reproduce in natural conditions that are new to them.
Cactus grower terms
Organisms that consume the corpses of other organisms.
Cactus grower terms
Death of the tissues of a localized part of an individual while the rest of the organism remains alive (burn, frostbite).
Cactus grower terms
Specific structures in the areoles of certain cacti that produce a sweet liquid attracting insects.
Cactus grower terms
Poisons that kill nematodes.
Cactus grower terms
Parasitic worms.
Cactus grower terms
Plants that have recently appeared in a given locality, newly introduced.
Cactus grower terms
A specimen selected to serve as the nomenclatural type until all the material on which the name of the taxon was based has been collected.
Cactus grower terms
Term referring to the determination of the level in the hierarchy of plant groups during their classification and categorization.
Cactus grower terms
A universal and stable system of names used in various fields of science and technology, including botany (botanical nomenclature).
Cactus grower terms
Plants that do not have the green pigment chlorophyll in their cells. Due to the presence of other pigments, their stems (in this case, cacti) are colored in various bright shades of red, orange, yellow and lilac.
Cactus grower terms
(From Latin nucella - nutlet) - the central multicellular part of the ovule, surrounded by coats (integuments).
Cactus grower terms
An individual structural unit of a nucleic acid, consisting of a phosphate, a five-carbon sugar, and a purine or pyrimidine.
Cactus grower terms
The natural, genetically inherent ability to produce daughter stem shoots (offsets) in a number of cactus species, or induced artificially by removal of the stem's growing point.
Cactus grower terms
Lateral shoots of cacti.
Cactus grower terms
A young shoot of a plant arising from the stem or root. Among hobbyists the terms "shoot" or "plantlet" are more commonly used.
Cactus grower terms
Individual development, the entire complex of a plant's life activities and structure, beginning with its origin from a fertilized egg cell, a vegetative bud, or the division of a mother cell, and continuing until the plant's death.
Cactus grower terms
Complex compounds of the substrate's soil fractions formed as a result of the decomposition of organic substances, for which carbon is an essential element.
Cactus grower terms
A component of soil that is of plant or animal origin.
Cactus grower terms
(From Greek osmos - pressure, push) - the ensemble of physico-chemical processes leading to thermodynamic equilibrium and the equalization of solution concentrations on both sides of a membrane. It is ensured by the slow transfer of low-mo…
Cactus grower terms
Difference in osmotic pressure across a membrane.
Cactus grower terms
Excess external pressure that must be applied to the solution side to stop osmosis — the influx of solvent into it through the semipermeable membrane separating them.
