Nectarine Fruit Development
The peach (''Prunus persica'') is a deciduous tree first domesticated and Agriculture, cultivated in China. It bears edible juicy fruits with various characteristics, most called peaches and the glossy-skinned, non-fuzzy varieties called nectarines. Peaches and #Nectarines, nectarines are the same species, though they are regarded commercially as different fruits. The tree is regarded as handsome and is planted in gardens for its springtime blooms in addition to fruit production. The peach tree is relatively short lived, usually not exceeding twenty years of age. However, the peach fruit is regarded as a symbol of longevity in several East Asian cultures. The specific name ''persica'' refers to its widespread cultivation in Persia (modern-day Iran), from where it was transplanted to Europe and in the 16th century to the Americas. It belongs to the genus ''Prunus'', which also includes the cherry, apricot, almond, and plum, and which is part of the Rosaceae, rose family. The p ...

Batsch
August Johann Georg Karl Batsch (28 October 1761 – 29 September 1802) was a German naturalist. He was a recognised authority on mushrooms, and also described new species of ferns, bryophytes, and seed plants. Life and career Batsch was born in Jena, Saxe-Weimar to George Lorenz Bratsch and Ernestine (''nee'' Franke) Bratsch. He studied at the Jena City School, and then had private tuition. He showed an aptitude for natural sciences and drawing, and so subsequently studied medicine and philosophy at the University of Jena (now known as the Friedrich Schiller University of Jena), entering in 1772 and obtaining his doctorate in philosophy in 1781 and in medicine in 1786, his supervisor being Justus Christian Loder. Batsch was married in 1787 to Amalie Pfaundel. They had three children, Friedrich (born 1789), George Friedrich Karl (1792), and Karoline (1795). He died in 1802 after a short illness. In 1786 Batsch began to teach natural history at the University of Jena and in 1787 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basal Shoot
Basal shoots, root sprouts, adventitious shoots, and suckers are words for various kinds of shoots that grow from adventitious buds on the base of a tree or shrub, or from adventitious buds on its roots. Shoots that grow from buds on the base of a tree or shrub are called basal shoots; these are distinguished from shoots that grow from adventitious buds on the roots of a tree or shrub, which may be called root sprouts or suckers. A plant that produces root sprouts or Stolon, runners is described as surculose. Water sprouts produced by adventitious buds may occur on the above-ground stem, branches or both of trees and shrubs. Suckers are shoots arising underground from the roots some distance from the base of a tree or shrub. __TOC__ In botany and ecology In botany, a root sprout or sucker is a severable plant that grows not from a seed but from the meristem of a root at the base of or a certain distance from the original tree or shrub. Root sprouts may emerge a substantial distan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornamental Plant
Ornamental plants or ''garden plants'' are plants that are primarily grown for their beauty but also for qualities such as scent or how they shape physical space. Many flowering plants and garden varieties tend to be specially bred cultivars that improve on the original species in qualities such as color, shape, scent, and long-lasting blooms. There are many examples of fine ornamental plants that can provide height, privacy, and beauty for any garden. These ornamental perennial plants have seeds that allow them to reproduce. One of the beauties of ornamental grasses is that they are very versatile and low maintenance. Almost all types of plant have ornamental varieties: trees, shrubs, climbers, grasses, succulents, aquatic plants, herbaceous perennials and annual plants. Non-botanical classifications include houseplants, bedding plants, hedges, plants for cut flowers and ''foliage plants''. The cultivation of ornamental plants comes under floriculture and tree nurseries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cultivar
A cultivar is a kind of Horticulture, cultivated plant that people have selected for desired phenotypic trait, traits and which retains those traits when Plant propagation, propagated. Methods used to propagate cultivars include division, root and stem cuttings, offsets, grafting, micropropagation, tissue culture, or carefully controlled seed production. Most cultivars arise from deliberate human genetic engineering, manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in ''#Formal definition, Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prunus Persica In Aveyron (2)
''Prunus'' is a genus of flowering trees and shrubs from the family Rosaceae. The genus includes plums, cherries, peaches, nectarines, apricots and almonds (collectively stonefruit). The genus has a cosmopolitan distribution, being native to the temperate regions of North America, the neotropics of South America, and temperate and tropical regions of Eurasia and Africa, There are about 340 accepted species . Many members of the genus are widely cultivated for their sweet, fleshy fruit and for decorative purposes of their flowers. ''Prunus'' fruit are drupes, or stone fruits. The fleshy mesocarp surrounding the endocarp is edible while the endocarp itself forms a hard, inedible shell called the pyrena ("stone" or "pit"). This shell encloses the seed (or "kernel"), which is edible in some species (such as sweet almonds), but poisonous in many others (such as apricot kernels). Besides being eaten off the hand, most ''Prunus'' fruit are also commonly used in processing, such as jam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extrafloral Nectaries
Nectar is a viscous, sugar-rich liquid produced by plants in glands called nectaries, either within the flowers with which it attracts pollinating animals, or by extrafloral nectaries, which provide a nutrient source to animal mutualists, which in turn provide herbivore protection. Common nectar-consuming pollinators include mosquitoes, hoverflies, wasps, bees, butterflies and moths, hummingbirds, honeyeaters and bats. Nectar is an economically important substance as it is the sugar source for honey. It is also useful in agriculture and horticulture because the adult stages of some predatory insects feed on nectar. For example, a number of predacious or parasitoid wasps (e.g., the social wasp species ''Apoica flavissima'') rely on nectar as a primary food source. In turn, these wasps then hunt agricultural pest insects as food for their young. Nectar is most often associated with flowering plants angiosperms, but it is also produced by other groups, including ferns ...

Petiole (botany)
In botany, the petiole () is the stalk that attaches the leaf blade to the Plant stem, stem. It is able to twist the leaf to face the sun, producing a characteristic foliage arrangement (spacing of blades), and also optimizing its exposure to sunlight. Outgrowths appearing on each side of the petiole in some species are called stipules. The terms wikt:petiolate, petiolate and wikt:apetiolate, apetiolate are applied respectively to leaves with and without petioles. Description The petiole is a stalk that attaches a leaf to the plant stem. In petiolate leaves the leaf stalk may be long (as in the leaves of celery and rhubarb), or short (for example basil). When completely absent, the blade attaches directly to the stem and is said to be Sessility (botany), sessile or apetiolate. Subpetiolate leaves have an extremely short petiole, and may appear sessile. The broomrape family Orobanchaceae is an example of a family in which the leaves are always sessile. In some other plant group ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lanceolate
The following terms are used to describe leaf plant morphology, morphology in the description and taxonomy (biology), taxonomy of plants. Leaves may be simple (that is, the leaf blade or 'lamina' is undivided) or compound (that is, the leaf blade is divided into two or more leaflet (botany), leaflets). The edge of the leaf may be regular or irregular, and may be smooth or have hair, bristles, or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf#Terminology, leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from ...

Terminal Bud
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. Overview The buds of many woody plants, especially in temperate or cold climates, are protected by a covering of modified leaves called ''scales'' which tightly enclose the more delicate parts of the bud. Many bud scales are covered by a gummy substance which serves as added protection. When the bud develops, the scales may enlarge somewhat but usually just drop off, leaving a series of horizontally-elongated scars on the surface of the growing stem. By means of these scars one can determine the age of any young branch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lenticel
A lenticel is a porous tissue consisting of cells with large intercellular spaces in the periderm of the secondarily thickened organs and the Bark (botany), bark of woody stems and roots of gymnosperms and dicotyledonous flowering plants. It functions as a pore, providing a pathway for the direct gas exchange, exchange of gases between the internal tissues and atmosphere through the bark, which is otherwise impermeable to gases. The name lenticel, pronounced with an , derives from its lenticular (lens (optics), lens-like) shape. The shape of lenticels is one of the characteristics used for tree identification. Evolution Before there was much evidence for the existence and functionality of lenticels, the fossil record has shown the first primary mechanism of aeration in early vascular plants to be the stomata. However, in woody plants, while the respiratory function of stomata is retained in the living epidermis of leaves and green stems, that function is lost where the epidermi ...

Weeping Tree
Weeping trees are trees characterized by soft, limp twigs. This characterization may lead to a bent crown and pendulous branches that can cascade to the ground. While weepyness occurs in nature, most weeping trees are cultivars. Because of their shape, weeping trees are popular in landscaping; generally they need a lot of space and are solitary so that their effect is more pronounced. There are over a hundred different types of weeping trees. Some trees, such as the cherry, have a variety of weeping cultivars. There are currently around 550 weeping cultivars in 75 different genera, although many have now disappeared from cultivation.Govaerts, R., Jablonski, E. & Michielsen, K. (2009).
