Cydonia Group
The Maleae (incorrectly Pyreae) are the apple tribe in the rose family, Rosaceae. The group includes a number of plants bearing commercially important fruits, such as apples and pears, while others are cultivated as ornamentals. Older taxonomies separated some of this group as tribe Crataegeae,G. K. Schulze-Menz 1964. ''Reihe Rosales''. in ''A. Engler's Syllabus der Pflanzenfamilien mit besonderer Berücksichtigung der Nutzpflanzen nebst einer Übersicht über die Florenreiche und Florengebiete der Erde'', Gebrüder Borntraeger, Berlin as the Cydonia group (a tentative placement), or some genera were placed in family Quillajaceae. The tribe consists exclusively of shrubs and small trees. Most have pomes, a type of accessory fruit that does not occur in other Rosaceae. All except ''Vauquelinia'' (with 15 chromosomes) have a basal haploid chromosome count of 17, instead of 7, 8, or 9 as in the other Rosaceae. There are approximately 28 genera that contain about 1100 species worl ...

Chromosome
A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones. These proteins, aided by chaperone proteins, bind to and condense the DNA molecule to maintain its integrity. These chromosomes display a complex three-dimensional structure, which plays a significant role in transcriptional regulation. Chromosomes are normally visible under a light microscope only during the metaphase of cell division (where all chromosomes are aligned in the center of the cell in their condensed form). Before this happens, each chromosome is duplicated (S phase), and both copies are joined by a centromere, resulting either in an X-shaped structure (pictured above), if the centromere is located equatorially, or a two-arm structure, if the centromere is located distally. The joined copies are now ca ...

Cydonia (genus)
The quince (; ''Cydonia oblonga'') is the sole member of the genus ''Cydonia'' in the Malinae subtribe (which also contains apples and pears, among other fruits) of the Rosaceae family. It is a deciduous tree that bears hard, aromatic bright golden-yellow pome fruit, similar in appearance to a pear. Ripe quince fruits are hard, tart, and astringent. They are seldom eaten raw, but are processed into marmalade, jam, paste (known as quince cheese) or alcoholic beverages. The quince tree is also grown as an ornamental plant for its attractive pale pink blossoms and other ornamental qualities. Description The tree grows high and wide. The fruit is long and across. The immature fruit is green with dense grey-white fine hair, most of which rubs off before maturity in late autumn when the fruit changes colour to yellow with hard, strongly perfumed flesh. The leaves are alternately arranged, simple, long, with an entire margin and densely pubescent with fine white hairs. The f ...

Sorbus Chamaemespilus
''Sorbus chamaemespilus'', the false medlar or dwarf whitebeam, is a species of ''Sorbus'' native to the mountains of central and southern Europe, from the Pyrenees east through the Alps to the Carpathians and the Balkans, growing at altitudes of up to 2500 m.Blamey, M. & Grey-Wilson, C. (1989). ''Flora of Britain and Northern Europe''. File:Sorbus-chamaemespilus-autumn.JPG, Tree in autumn File:Chamaemespilus alpinus (9393819230).jpg, fruit Description It is a deciduous shrub growing to 2–3 m tall. The leaves are spirally arranged, oval-elliptic, 3–7 cm long, with an acute apex and a serrated margin; they are green on both sides, without the white felting found on most whitebeams.

Aronia
''Aronia'' is a genus of deciduous shrubs, the chokeberries, in the family Rosaceae native to eastern North America and most commonly found in wet woods and swamps. The genus Aronia is considered to have 3 species. The most common and widely used is ''Aronia melanocarpa'' (black chokeberry) which emerged from Eastern North America. The lesser known ''Aronia arbutifolia'' (red chokeberry) and the hybrid form of the abovementioned species called ''Aronia prunifolia'' (purple chokeberry) were first cultivated in Central and Eastern North America. In the eighteenth century, the first shrubs of the best-known species ''Aronia melanocarpa'' reached Europe where they were first cultivated in Scandinavia and Russia. Chokeberries are cultivated as ornamental plants and as food products. The sour berries, or aronia berries, can be eaten raw off the bush, but are more frequently processed. They can be used to make wine, jam, syrup, juice, soft spreads, tea, salsa, extracts, beer, i ...
