In botany, a bud is an undeveloped or embryonic shoot and normally occurs in the axil of a leaf or at the tip of a stem. Once formed, a bud may remain for some time in a dormant condition, or it may form a shoot immediately. Buds may be specialized to develop flowers or short shoots or may have the potential for general shoot development. The term bud is also used in zoology, where it refers to an outgrowth from the body which can develop into a new individual.
Tubers are a type of enlarged structure used as storage organs for nutrients in some plants. They are used for the plant's perennation, to provide energy and nutrients for regrowth during the next growing season, and as a means of asexual reproduction. Stem tubers form thickened rhizomes or stolons ; well known species with stem tubers include the potato and yam. Some writers also treat modified lateral roots under the definition; these are found in sweet potatoes, cassava, and dahlias.
Drosera, which is commonly known as the sundews, is one of the largest genera of carnivorous plants, with at least 194 species. These members of the family Droseraceae lure, capture, and digest insects using stalked mucilaginous glands covering their leaf surfaces. The insects are used to supplement the poor mineral nutrition of the soil in which the plants grow. Various species, which vary greatly in size and form, are native to every continent except Antarctica.
Dormancy is a period in an organism's life cycle when growth, development, and physical activity are temporarily stopped. This minimizes metabolic activity and therefore helps an organism to conserve energy. Dormancy tends to be closely associated with environmental conditions. Organisms can synchronize entry to a dormant phase with their environment through predictive or consequential means. Predictive dormancy occurs when an organism enters a dormant phase before the onset of adverse conditions. For example, photoperiod and decreasing temperature are used by many plants to predict the onset of winter. Consequential dormancy occurs when organisms enter a dormant phase after adverse conditions have arisen. This is commonly found in areas with an unpredictable climate. While very sudden changes in conditions may lead to a high mortality rate among animals relying on consequential dormancy, its use can be advantageous, as organisms remain active longer and are therefore able to make greater use of available resources.
Pruning is a horticultural, arboricultural, and silvicultural practice involving the selective removal of certain parts of a plant, such as branches, buds, or roots.
A turion is a type of bud that is capable of growing into a complete plant. A turion may be an underground bud. Many members of the genus Epilobium are known to produce turions at or below ground level.
The axillary bud is an embryonic or organogenic shoot located in the axil of a leaf. Each bud has the potential to form shoots, and may be specialized in producing either vegetative shoots or reproductive shoots (flowers). Once formed, a bud may remain dormant for some time, or it may form a shoot immediately.
Drosera rotundifolia, the round-leaved sundew, roundleaf sundew, or common sundew, is a carnivorous species of flowering plant that grows in bogs, marshes and fens. One of the most widespread sundew species, it has a circumboreal distribution, being found in all of northern Europe, much of Siberia, large parts of northern North America, Korea and Japan but is also found as far south as California, Mississippi and Alabama in the United States of America and in New Guinea.
Hibernaculum (hi-buhr-NAK-yuh-luhm) may refer to:
The Indiana bat is a medium-sized mouse-eared bat native to North America. It lives primarily in Southern and Midwestern U.S. states and is listed as an endangered species. The Indiana bat is grey, black, or chestnut in color and is 1.2–2.0 in long and weighs 4.5–9.5 g (0.16–0.34 oz). It is similar in appearance to the more common little brown bat, but is distinguished by its feet size, toe hair length, pink lips, and a keel on the calcar.
Drosera intermedia, commonly known as the oblong-leaved sundew, spoonleaf sundew, or spatulate leaved sundew, is an insectivorous plant species belonging to the sundew genus. It is a temperate or tropical species native to Europe, southeastern Canada, the eastern half of the United States, Cuba, Hispaniola, and northern South America.
Pinguicula alpina, also known as the alpine butterwort, is a species of carnivorous plant native to high latitudes and altitudes throughout Eurasia. It is one of the most widespread Pinguicula species, being found in mountainous regions from Iceland to the Himalayas. Native to cold climates, it is a temperate species, forming prostrate rosettes of green to red leaves and white flowers in the summer and a tight hibernaculum during a period of winter dormancy in the winter. Like all members of the genus, P. alpina uses mucilaginous glands covering the surface of its summer leaves to attract, trap, and digest arthropod prey.
A hibernaculum is a place in which an animal seeks refuge, such as a bear using a cave to overwinter. The word can be used to describe a variety of shelters used by many kinds of animals, including insects, toads, lizards, snakes, bats, rodents, and primates of various species.
Pinguicula vulgaris, the common butterwort, is a perennial carnivorous plant in the bladderwort family, Lentibulariaceae.
The chilling requirement of a fruit is the minimum period of cold weather after which a fruit-bearing tree will blossom. It is often expressed in chill hours, which can be calculated in different ways, all of which essentially involve adding up the total amount of time in a winter spent at certain temperatures.
Pinguicula longifolia, commonly known as the long-leaved butterwort, is a perennial carnivorous subalpine plant of the Central Pyrenees, found on both sides of the border. It catches its prey by using its modified leaves that lie on the ground and have “densely covered stalked glands that bear a droplet of sticky mucilage on its top.” The need to capture arthropods is driven by the lack of nutrients present in the soil. P. l. subsp. longifolia obtain their nutrition primarily from flying insects, mainly diptera, which replenished the carnivorous plant with nitrogen. P. l. subsp. longifolia grows in wet shady areas and on vertical or overhanging limestone walls. It has been found at altitudes between 700 – 1900 meters. In the spring, the winter buds open and the first carnivorous leaves present themselves. These leaves are then followed by the flowers in early summer. Throughout summer the leaves can grow up to 14 cm in length and have glands present on both sides of the leaves, which is highly characteristic of P. l. subsp. longifolia. More carnivorous leaves arise throughout summer, and when the conditions become unfavourable, around autumn, a protective winter casing composed of scale like leaves is produced, in the centre of the rosette, called the hibernacula, also known as the plant bud. The leaves halt production and the old leaves wither and decay; P. l. subsp. longifolia is now ready for the winter dormancy. There must be optimal growth during the summer for P. l. subsp. longifolia, otherwise they produce weakened hibernacula which rot very easily.
Chamaedorea elegans, the neanthe bella palm or parlour palm, is a species of small palm tree native to the rainforests in Southern Mexico and Guatemala. The parlor palm is one of the most extensively sold houseplant palms in the world. It is one of several species with leaves that are harvested as xate.
Gynaephora groenlandica, the Arctic woolly bear moth, is an erebid moth native to the High Arctic in the Canadian archipelago, Greenland and Wrangel Island in Russia. It is known for its slow rate of development, as its full caterpillar life cycle may extend up to 7 years, with moulting occurring each spring. This species remains in a larval state for the vast majority of its life. Rare among Lepidoptera, it undergoes an annual period of diapause that lasts for much of the calendar year, as G. groenlandica is subject to some of the longest, most extreme winters on Earth. In this dormant state, it can withstand temperatures as low as −70 °C. The Arctic woolly bear moth also exhibits basking behavior, which aids in temperature regulation and digestion and affects both metabolism and oxygen consumption. Females generally do not fly, while males usually do.
Ditula angustiorana, the red-barred tortrix, is a moth of the family Tortricidae found in Africa, Asia, Europe and North Africa. Other common names are the fruit-tree tortrix and the vine tortrix. The moth was first described by Adrian Hardy Haworth in 1811.
Pinguicula, commonly known as butterworts, is a genus of carnivorous flowering plants in the family Lentibulariaceae. They use sticky, glandular leaves to lure, trap, and digest insects in order to supplement the poor mineral nutrition they obtain from the environment. Of the roughly 80 currently known species, 13 are native to Europe, 9 to North America, and some to northern Asia. The largest number of species is in South and Central America.
