Apple Chat Fruit
Apple chat fruit MLO, also known as "apple small fruit" and "chat fruit of apple", is a mycoplasma-like organism (MLO) that affects only apple trees, specifically Lord Lambourne and Tydeman's Early Worcester, though in North America, Turley, Winesap, Jonathan, and Golden Delicious can be affected. Symptoms include delayed fruit development, smaller green apples during harvest, delayed fruit drop, and circular spots on the apples themselves. The disease is widespread throughout Europe, especially England and Wales, but is also present in parts of North America, South Africa, and New Zealand. There are no known insect vectors and no transmission method other than grafting is known. The disease itself is not fully systemic and virulency is varied among individuals.

Phytoplasma
Phytoplasmas are obligate intracellular parasites of plant phloem tissue and of the insect vectors that are involved in their plant-to-plant transmission. Phytoplasmas were discovered in 1967 by Japanese scientists who termed them mycoplasma-like organisms. Since their discovery, phytoplasmas have resisted all attempts at ''in vitro'' culture in any cell-free medium; routine cultivation in an artificial medium thus remains a major challenge. Phytoplasmas are characterized by the lack of a cell wall, a pleiomorphic or filamentous shape, a diameter normally less than 1 μm, and a very small genome. Phytoplasmas are pathogens of agriculturally important plants, including coconut, sugarcane, and sandalwood, in which they cause a wide variety of symptoms ranging from mild yellowing to death. Phytoplasmas are most prevalent in tropical and subtropical regions. They are transmitted from plant to plant by vectors (normally sap-sucking insects such as leafhoppers) in which they both ...

Apple Tree
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 t ...

List Of 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 ''Malus'' ( or ) is a genus of about 30–55 species of small deciduous trees or shrubs in the family Rosaceae, including the domesticated orchard apple, crab apples, wild apples, and rainberries. The genus is native to the temperate zo ...''. Table of apples Cider apple ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jonathan (apple)
The Jonathan apple is a medium-sized sweet apple, with a touch of acid and a tough but smooth skin. It is closely related to the Esopus Spitzenburg apple, good for eating fresh and for cooking. Sugar 14%, acid 9g/litre, vitamin C 5mg/100g. History There are two alternative theories about the origin of the Jonathan apple. The first is that it was grown by Rachel Negus Higley. Mrs. Higley gathered seeds from the local cider mill in Connecticut before the family made their journey to the wilds of Ohio in 1796 where she planted them. She continued to carefully cultivate her orchard to maturity and named the resulting variety after a young local boy that frequented her orchard: Jonathan Lash. The other, and more accepted, theory is that it originated from an Esopus Spitzenburg seedling in 1826 from the farm of Philip Rick(s) in Woodstock, Ulster County, New York. Although it may have originally been called the "Ricks" apple, it was soon renamed by Judge Buel, President of Albany Ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Golden Delicious
'Golden Delicious' is a cultivar of apple. It is one of the 15 most popular apple cultivars in the United States. It is not closely related to ' Red Delicious'. History Golden Delicious arose from a chance seedling, possibly a hybrid of ' Grimes Golden' and ' Golden Reinette'. The original tree was found on the Mullins' family farm in Clay County, West Virginia, United States, and was locally known as Mullin's Yellow Seedling and Annit apple. In Clay County, George Deems was instrumental in preserving and perpetuating the original Stark's Golden delicious apple tree on A. H. Mullins property back in 1938. The famed tree came to the attention of the Stark Brothers a number of years before, when Mr. Mullins sent three apples to Mr. Stark one fine April. The Golden Delicious' long keeping qualities were soon abundantly evident to Mr. Stark, as well as to United States Pomologist Colonel Brackett, in Washington, and the nursery bought the tree and ground on which it stands from M ...
