Freestone Peach
The peach (''Prunus persica'') is a deciduous tree first domesticated and cultivated in Zhejiang province of Eastern China. It bears edible juicy fruits with various characteristics, most called peaches and others (the glossy-skinned, non-fuzzy varieties), nectarines. The specific name ''persica'' refers to its widespread cultivation in Persia (modern-day Iran), from where it was transplanted to Europe. It belongs to the genus ''Prunus'', which includes the cherry, apricot, almond, and plum, in the rose family. The peach is classified with the almond in the subgenus ''Amygdalus'', distinguished from the other subgenera by the corrugated seed shell (endocarp). Due to their close relatedness, the kernel of a peach stone tastes remarkably similar to almond, and peach stones are often used to make a cheap version of marzipan, known as persipan. Peaches and nectarines are the same species, though they are regarded commercially as different fruits. The skin of nectarines lacks the ...

Otto Wilhelm Thomé
Otto Wilhelm Thomé (1840–1925) was a German botanist and botanical artist from Cologne, best known for his compendium of botanical illustrations ''Flora von Deutschland, Österreich und der Schweiz in Wort und Bild für Schule und Haus'' (Flora of Germany, Austria and Switzerland in Word and Picture for School and Home), the first of 4 volumes with a total of 572 botanical illustrations, published in 1885 in Gera, Germany. Another 8 volumes were added to the set by Walter Migula with the republication in 1903. From 1897 to 1899, he was the Headmaster of the Hansagymnasium Köln, Business School Cologne.

Rosaceae
Rosaceae (), the rose family, is a medium-sized family of flowering plants that includes 4,828 known species in 91 genera. The name is derived from the type genus ''Rosa''. Among the most species-rich genera are ''Alchemilla'' (270), ''Sorbus'' (260), '' Crataegus'' (260), ''Cotoneaster'' (260), ''Rubus'' (250), and ''Prunus'' (200), which contains the plums, cherries, peaches, apricots, and almonds. However, all of these numbers should be seen as estimates—much taxonomic work remains. The family Rosaceae includes herbs, shrubs, and trees. Most species are deciduous, but some are evergreen. They have a worldwide range but are most diverse in the Northern Hemisphere. Many economically important products come from the Rosaceae, including various edible fruits, such as apples, pears, quinces, apricots, plums, cherries, peaches, raspberries, blackberries, loquats, strawberries, rose hips, hawthorns, and almonds. The family also includes popular ornamental trees and shrubs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flower
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae). The biological function of a flower is to facilitate reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) resulting from cross-pollination or allow selfing (fusion of sperm and egg from the same flower) when self-pollination occurs. There are two types of pollination: self-pollination and cross-pollination. Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is when pollen is transferred from the anther of one flower to the stigma of another flower on a different individual of the same species. Self-pollination happens in flowers where the stamen and carpel mature at the same time, and are positi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pinnate
Pinnation (also called pennation) is the arrangement of feather-like or multi-divided features arising from both sides of a common axis. Pinnation occurs in biological morphology, in crystals, such as some forms of ice or metal crystals, and in patterns of erosion or stream beds. The term derives from the Latin word ''pinna'' meaning "feather", "wing", or "fin". A similar concept is "pectination," which is a comb-like arrangement of parts (arising from one side of an axis only). Pinnation is commonly referred to in contrast to "palmation," in which the parts or structures radiate out from a common point. The terms "pinnation" and "pennation" are cognate, and although they are sometimes used distinctly, there is no consistent difference in the meaning or usage of the two words.Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 Plants Botanically, pinnation is an arrangement of discr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lanceolate
The following is a list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (a single leaf blade or lamina) or compound (with several leaflets). The edge of the leaf may be regular or irregular, may be smooth or bearing hair, bristles or spines. For more terms describing other aspects of leaves besides their overall morphology see the 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 the same plant. For example, whether to call leaves on the same tree "acuminate", "lanceolate", or "linear" could ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leaf
A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper (adaxial) and lower ( abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll that is essential for photosynthesis as it absorbs light ...

Amygdalus Persica2
''Prunus'' subg. ''Prunus'' is a subgenus of ''Prunus''. This subgenus includes plums, apricots and bush cherries. Most species inside this subgenus bear fruit that is sugary, storing large amounts of energy, which is why most ''Prunus'' species' fruits are soft and rubbery. Some species conventionally included in ''Prunus'' subg. ''Amygdalus'' are clustered with plum/apricot species according to molecular phylogenetic studies. Shi et al. (2013) has incorporated subg. ''Amygdalus'' into subg. ''Prunus,'' thereby including almonds and peaches in this subgenus. Sections according to Shi et al. (2013) Shi et al. (2013) divide subg. ''Prunus'' into seven sections: sect. ''Amygdalus'', sect. ''Armeniaca'', sect. ''Emplectocladus'', sect. ''Microcerasus'', sect. ''Persicae'', sect. ''Prunocerasus'' and sect. ''Prunus''. They form three clades. The basal clade is sect. ''Emplectocladus'' which is sometimes treated as a subgenus. The other two clades are the ''Amygdalus''-''Persicae'' c ...

Gene
In biology, the word gene (from , ; "...Wilhelm Johannsen coined the word gene to describe the Mendelian units of heredity..." meaning ''generation'' or ''birth'' or ''gender'') can have several different meanings. The Mendelian gene is a basic unit of heredity and the molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA. There are two types of molecular genes: protein-coding genes and noncoding genes. During gene expression, the DNA is first copied into RNA. The RNA can be directly functional or be the intermediate template for a protein that performs a function. The transmission of genes to an organism's offspring is the basis of the inheritance of phenotypic traits. These genes make up different DNA sequences called genotypes. Genotypes along with environmental and developmental factors determine what the phenotypes will be. Most biological traits are under the influence of polygenes (many different genes) as well as gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trichome
Trichomes (); ) are fine outgrowths or appendages on plants, algae, lichens, and certain protists. They are of diverse structure and function. Examples are hairs, glandular hairs, scales, and papillae. A covering of any kind of hair on a plant is an indumentum, and the surface bearing them is said to be pubescent. Algal trichomes Certain, usually filamentous, algae have the terminal cell produced into an elongate hair-like structure called a trichome. The same term is applied to such structures in some cyanobacteria, such as '' Spirulina'' and ''Oscillatoria''. The trichomes of cyanobacteria may be unsheathed, as in ''Oscillatoria'', or sheathed, as in ''Calothrix''. These structures play an important role in preventing soil erosion, particularly in cold desert climates. The filamentous sheaths form a persistent sticky network that helps maintain soil structure. Plant trichomes Plant trichomes have many different features that vary between both species of plants an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Persipan
Persipan (from ''Persicus'' (peach) and ''marzipan''; also known as Parzipan) is a material used in confectionery. It is similar to marzipan but, instead of almonds, is made with apricot or peach kernels. Persipan consists of 40% ground kernels and 60% sugar. The kernels have a strong bitter flavour caused by the presence of amygdalin, a toxic cyanogenic glycoside which has to be detoxified before the kernels can be used. The cores are normally not used otherwise, originally making persipan lower-priced than marzipan. It also has a somewhat different taste. Persipan often contains 0.5% starch so that it can be easily differentiated from marzipan with an iodine test. Persipan is generally used in confectionery in place of marzipan and as an ingredient of pastry and sweet foods, such as Stollen Stollen ( or ) is a fruit bread of nuts, spices, and dried or candied fruit, coated with powdered sugar or icing sugar and often containing marzipan.

Marzipan
Marzipan is a confectionery, confection consisting primarily of sugar, honey, and almond meal (ground almonds), sometimes augmented with almond oil or extract. It is often made into Confectionery, sweets; common uses are chocolate-covered marzipan and small marzipan imitations of fruits and vegetables. It can also be used in biscuits or rolled into thin sheets and glazed for icing cakes, primarily birthday cakes, wedding cakes and Christmas cakes. Almond paste, Marzipan paste may also be used as a baking ingredient, as in stollen or banket (food), banket. In some countries, it is shaped into small figures of animals as a traditional treat for New Year's Day or Christmas. Marzipan is also used in Tortell, and in some versions of king cake eaten during the Carnival season. Around the world Europe The Geographical indications and traditional specialities in the European Union recognize two marzipans in Europe. One in Toledo (Spain) and another one in Lübeck (Germany).
