Jonathan (apple)
''Jonathan'' is a medium-sized sweet apple, with a touch of acid and a tough but smooth skin, good for eating fresh and for cooking. Parentage = Esopus Spitzenburg x ? *Sugar 12.5% *Acid 7.7 g/litre *Vitamin C 5mg/100g. History There are two alternative theories about the origin of the Jonathan apple. The first theory; it was grown by Rachel Negus Higley, who gathered seeds from the local cider mill in Connecticut. This was 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, Jonathan Lash, who frequented her orchard. The other, more accepted, theory is that it originated from an Esopus Spitzenburg seedling in 1826, on the farm of Philip Rick(s) in Woodstock (town), New York, Woodstock, Ulster County, New York. A DNA profiling study supports this descent. Although it may have originally been called the "Ricks" apple, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malus Domestica
An apple is a round, edible fruit produced by an apple tree (''Malus'' spp.). Fruit trees of the orchard or domestic apple (''Malus domestica''), the most widely grown in the genus, are agriculture, cultivated worldwide. The tree originated in Central Asia, where its wild ancestor, ''Malus sieversii'', is still found. Apples have been grown for thousands of years in Eurasia before they were introduced to North America by European colonization of the Americas, European colonists. Apples have cultural significance in many mythological, mythologies (including Norse mythology, Norse and Greek mythology, Greek) and religions (such as Christianity in Europe). Apples grown from seeds tend to be very different from those of their parents, and the resultant fruit frequently lacks desired characteristics. For commercial purposes, including botanical evaluation, apple cultivars are propagated by clonal grafting onto rootstocks. Apple trees grown without rootstocks tend to be larger and ...

Jonagold
Jonagold is a cultivar of apple that is a cross between the crisp Golden Delicious and the blush-crimson Jonathan; the name ''Jonagold'' is a portmanteau of these two variety names. It was developed in 1943 in New York State Agricultural Experiment Station of Cornell University's College of Agriculture and Life Sciences, selected as N.Y. 43013-1 in 1953, officially released in 1968 by Roger Way. They form a large sweet fruit with a thin skin that is green-yellow with streaks of crimson. The flesh is creamy yellow with a breaking texture and outstanding flavor. Because of their large size they are now favored by commercial growers in many parts of the world, and the apples can last two month in refrigerated storage and ten months in controlled atmosphere storage. Jonagold is triploid, with sterile pollen, and as such, requires a second type of apple for pollen and is incapable of pollenizing other cultivars. It is susceptible to the diseases apple scab, powdery mildew, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apple Canker
A plant canker is a small area of dead tissue, which grows slowly, often over years. Some cankers are of only minor consequence, but others are ultimately lethal and therefore can have major economic implications for agriculture and horticulture. Their causes include a wide range of organisms as fungi, bacteria, mycoplasmas and viruses. The majority of canker-causing organisms are bound to a unique host species or genus, but a few will attack other plants. Weather (via frost or windstorm damage) and animal damage can also cause stress to the plant resulting in cankers. Other causes of cankers is pruning when the bark is wet or using un-sterilized tools. Although fungicides or bactericides can treat some cankers, often the only available treatment is to destroy the infected plant to contain the disease. Examples * Apple canker, caused by the fungus ''Neonectria galligena'' formerly Nectria galligena. * Ash bacterial canker, now understood to be caused by the bacterium ''Pseudo ...

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. In Europe it is listed as a quaran ...

Cedar Apple Rust
''Gymnosporangium juniperi-virginianae'' is a plant pathogen that causes cedar-apple rust. In virtually any location where apples or crabapples (''Malus'') and eastern red cedar (''Juniperus virginiana'') coexist, cedar apple rust can be a destructive or disfiguring disease on both the apples and cedars. Apples, crabapples, and eastern red cedar are the most common hosts for this disease. Similar diseases can be found on quince and Crataegus, hawthorn and many species of juniper can substitute for the eastern red cedars. Symptoms On the apple tree, the infections occur on leaves, fruit and young twigs. The brightly colored spots produced on the leaves make it easy to identify. Small, yellow-orange spots appear on the upper surfaces of the leaves, anytime from April to June. These spots gradually enlarge and turn orange or red and may show concentric rings of color. Drops of orange liquid may be visible on the spots. Later in the season, black dots appear on the orange spots on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Powdery Mildew
Powdery mildew is a fungus, fungal disease that affects a wide range of plants. Powdery mildew diseases are caused by many different species of Ascomycota, ascomycete fungi in the order Erysiphales. Powdery mildew is one of the easier plant diseases to identify, as the signs of the causal pathogen are quite distinctive. Infected plants display white powdery spots on the leaves and stems. This mycelial layer may quickly spread to cover all of the leaves. The lower leaves are the most affected, but the mildew can appear on any above-ground part of the plant. As the disease progresses, the spots get larger and denser as large numbers of asexual spores are formed, and the mildew may spread up and down the length of the plant. Powdery mildew grows well in environments with high humidity and moderate temperatures; greenhouses provide an ideal moist, temperate environment for the spread of the disease. This causes harm to agricultural and horticultural practices where powdery mildew may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apple Scab
Apple scab is a common disease of plants in the rose family (Rosaceae) that is caused by the ascomycete fungus ''Venturia inaequalis''. While this disease affects several plant genera, including '' Sorbus, Cotoneaster,'' and '' Pyrus'', it is most commonly associated with the infection of '' Malus'' trees, including species of flowering crabapple, as well as cultivated apple. The first symptoms of this disease are found in the foliage, blossoms, and developing fruits of affected trees, which develop dark, irregularly-shaped lesions upon infection. Although apple scab rarely kills its host, infection typically leads to fruit deformation and premature leaf and fruit drop, which enhance the susceptibility of the host plant to abiotic stress and secondary infection.Jha, G., Thakur, K., & Thakur, P. (2009). The ''Venturia'' Apple Pathosystem: Pathogenicity Mechanisms and Plant Defense Responses. ''Journal of Biomedicine and Biotechnology'', 2009. doi:10.1155/2009/680160 The reduction ...

Wealthy (apple)
The Wealthy is an American apple cultivar, and was the earliest to thrive in the Minnesota climate. Horticulturalist Peter Gideon Farmhouse, Peter Gideon grew it after years of trial and error with various apple varieties, and the fruit was described in 1869. History Before 1868, only crab apples grew reliably in Minnesota. Indigenous peoples in the area harvested other crops, but they did not grow apples. Early White settlers to Minnesota tried to grow apples using seeds and seedlings from their former homes to the east and the south, but their plants died, usually because of Winter in Minnesota, the region's harsh winters. In 1853, Peter Gideon moved to Minnesota for health reasons and took a homestead with his family on the shores of Lake Minnetonka, near Excelsior, Minnesota, Excelsior. He had learned fruit-growing as a child, and when he arrived on his new land, he planted a bushel of apple seeds he had brought with him from his former home in Maine, Illinois.Downing, Frui ...

Northern Spy
Northern Spy also called 'Spy' and 'King', is a cultivar of domesticated apple that originated on the farm of Oliver Chapin in East Bloomfield, New York, in about 1840. It is popular in upstate New York. The Northern Spy was one of four apples honored by the United States Postal Service in a 2013 set of four 33¢ stamps commemorating historic strains, joined by Baldwin, Golden Delicious, and Granny Smith. Description Northern Spy produces fairly late in the season (late October and beyond). Skin color is a green ground, flushed with red stripes where not shaded. The white flesh is juicy, crisp and mildly sweet with a rich, aromatic subacid flavor, noted for high vitamin C content. Its characteristic flavor is tarter than most popular varieties, and its flesh is harder or crunchier than most, with a thin skin. Uses Northern Spy is commonly used for desserts and pies, as well as juice and cider. It is an excellent apple for storage, tending to last long due to late maturation. ...
