Ashmead's Kernel
Ashmead's Kernel is a triploid cultivar of apple. Traditionally, Ashmead's Kernel was thought to be diploid but a poor pollinator. Origin Ashmead's Kernel is often reported as having been raised by Dr Ashmead in Gloucester, England in the 18th century. However, Christine Leighton of the Gloucestershire Orchard Group suggests that the originator may have been William Ashmead, a lawyer who died in 1782. Description Growing This dessert apple is of medium size, on average 83mm in diameter on vigorous rootstock and has a flat round shape. The base colour of the apple is greenish yellow, yet has a dull russet colour all over; sometimes there are brownish red stripes. When first cut open, the flesh is white, then it soon develops a brown tint. Ashmead's Kernel makes a good apple juice because of its sweet sharp flavour. Culture Produces an upright spreading tree, that generally crops well, though on exposed sites it can be irregular. It is a cultivar that is susceptible to bi ...

Malus Pumila
An apple is an edible fruit produced by an apple tree (''Malus domestica''). Apple trees are cultivated worldwide and are the most widely grown species in the genus ''Malus''. The tree originated in Central Asia, where its wild ancestor, '' Malus sieversii'', is still found today. Apples have been grown for thousands of years in Asia and Europe and were brought to North America by European colonists. Apples have religious and mythological significance in many cultures, including Norse, Greek, and European Christian tradition. Apples grown from seed tend to be very different from those of their parents, and the resultant fruit frequently lacks desired characteristics. Generally, apple cultivars are propagated by clonal grafting onto rootstocks. Apple trees grown without rootstocks tend to be larger and much slower to fruit after planting. Rootstocks are used to control the speed of growth and the size of the resulting tree, allowing for easier harvesting. There are more ...

Gloucester
Gloucester ( ) is a cathedral city and the county town of Gloucestershire in the South West of England. Gloucester lies on the River Severn, between the Cotswolds to the east and the Forest of Dean to the west, east of Monmouth and east of the border with Wales. Including suburban areas, Gloucester has a population of around 132,000. It is a port, linked via the Gloucester and Sharpness Canal to the Severn Estuary. Gloucester was founded by the Romans and became an important city and ''colony'' in AD 97 under Emperor Nerva as '' Colonia Glevum Nervensis''. It was granted its first charter in 1155 by Henry II. In 1216, Henry III, aged only nine years, was crowned with a gilded iron ring in the Chapter House of Gloucester Cathedral. Gloucester's significance in the Middle Ages is underlined by the fact that it had a number of monastic establishments, including: St Peter's Abbey founded in 679 (later Gloucester Cathedral), the nearby St Oswald's Priory, Glouce ...

England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century. The English language, the Anglican Church, and Eng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ploidy
Ploidy () is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes. Sets of chromosomes refer to the number of maternal and paternal chromosome copies, respectively, in each homologous chromosome pair, which chromosomes naturally exist as. Somatic cells, tissues, and individual organisms can be described according to the number of sets of chromosomes present (the "ploidy level"): monoploid (1 set), diploid (2 sets), triploid (3 sets), tetraploid (4 sets), pentaploid (5 sets), hexaploid (6 sets), heptaploid or septaploid (7 sets), etc. The generic term polyploid is often used to describe cells with three or more chromosome sets. Virtually all sexually reproducing organisms are made up of somatic cells that are diploid or greater, but ploidy level may vary widely between different organisms, between different tissues within the same organism, and at different stages in an organism's life cycle.

Cultivar
A cultivar is a type of cultivated plant that people have selected for desired traits and when propagated retain those traits. Methods used to propagate cultivars include: division, root and stem cuttings, offsets, grafting, tissue culture, or carefully controlled seed production. Most cultivars arise from purposeful human 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'': 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 that share the unique characteristics that define the cultivar. was coined as a term meaning "cultivated vari ...

Rootstock
A rootstock is part of a plant, often an underground part, from which new above-ground growth can be produced. It could also be described as a stem with a well developed root system, to which a bud from another plant is grafted. It can refer to a rhizome or underground stem. In grafting, it refers to a plant, sometimes just a stump, which already has an established, healthy root system, onto which a cutting or a bud from another plant is grafted. In some cases, such as vines of grapes and other berries, cuttings may be used for rootstocks, the roots being established in nursery conditions before planting them out. The plant part grafted onto the rootstock is usually called the scion. The scion is the plant that has the properties that propagator desires above ground, including the photosynthetic activity and the fruit or decorative properties. The rootstock is selected for its interaction with the soil, providing the roots and the stem to support the new plant, obtaining the ne ...

Bitter Pit
Bitter pit is a disorder in apple fruits, now believed to be induced by calcium deficiency. It occurs less commonly in pears. The disease was probably first reported in Germany where it was known as ''Stippen''.Jaeger, G (1869) Uber das Peliz oder Stippinwerden Kernobstfrucht. Illus. Monash obst u-Weinbau 16: 16 : 318–319. It was also known as "Baldwin spot" and "blotchy cork" in North America. The name "bitter pit" was first used by Cobb in Australia in 1895.Cobb, N.A. (1895). Diseases of plants and their remedies. 11. Bitter Pit of apples. Agric. Gaz.N.S.W. 6 : 859–861. The disease has been shown as non-pathological and is now known as a disorder. When it occurs on the tree, it is known as "tree pit"; it may also occur in storage, when it is known as "storage pit". Symptoms The affected fruit have dark spots, about ½ cm diameter, which occur on the skin or in the flesh or both. The cells in the spots are dead (necrotic), and turn brown-b ...

Fire Blight
Fire blight, also written fireblight, is a contagious disease affecting apples, pears, and some other members of the family Rosaceae. It is a serious concern to apple and pear producers. Under optimal conditions, it can destroy an entire orchard in a single growing season. The causal pathogen is ''Erwinia amylovora'', a Gram-negative bacterium in the genus '' Erwinia'', order Enterobacterales. It is a short rod with rounded ends and many peritrichous flagellae. Pears are the most susceptible, but apples, loquat, crabapples, quinces, hawthorn, cotoneaster, '' Pyracantha'', raspberry and some other rosaceous plants are also vulnerable. The disease is believed to be indigenous to North America, from where it spread to most of the rest of the world. Fire blight is not believed to be present in Australia though it might possibly exist there. It has been a major reason for a long-standing embargo on the importation of New Zealand apples to Australia. Japan was likewise be ...

Apple Cultivars
Over 7,500 cultivars of the culinary or eating apple (''Malus domestica'') are known. Some are extremely important economically as commercial products, though the vast majority are not suitable for mass production. In the following list, use for "eating" means that the fruit is consumed raw, rather than cooked. Cultivars used primarily for making cider are indicated. Those varieties marked have gained the Royal Horticultural Society's Award of Garden Merit. This list does not include the species and varieties of apples collectively known as crab apples, which are grown primarily for ornamental purposes, though they may be used to make jelly or compote. These are described under '' Malus''. Table of apples Cider apples Cider apples are a variety of apples that may be far too sour or bitter for fresh eating, but are used for making cider. Varieties in ''italics'' are used for both cider and eating purposes. shp = sharp, swt = sweet, bswt = bittersweet, bshp = bitt ...
