Apple
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 ...

Biennial Plant
A biennial plant is a flowering plant that, generally in a temperate climate, takes two years to complete its biological life cycle. Background In its first year, the biennial plant undergoes primary growth, during which its vegetative structures (leaves, stems, and roots) develop. Usually, the stem of the plant remains short and the leaves are low to the ground, forming a rosette. After one year's growing season, the plant enters a period of dormancy for the colder months. Many biennials require a cold treatment, or vernalization before they will flower. During the next spring or summer, the stem of the biennial plant elongates greatly, or "bolts". The plant then flowers, producing fruits and seeds before it finally dies. There are far fewer biennials than either perennial plants or annual plants. Biennials do not always follow a strict two-year life cycle: most plants in the wild can take three or more years to mature. Rosette leaf size has been found to predict when a pla ...

Self-sterile
Self-incompatibility (SI) is a general name for several genetic mechanisms that prevent self-fertilization in sexually reproducing organisms, and thus encourage outcrossing and allogamy. It is contrasted with separation of sexes among individuals (dioecy), and their various modes of spatial ( herkogamy) and temporal (dichogamy) separation. SI is best-studied and particularly common in flowering plants, although it is present in other groups, including sea squirts and fungi. In plants with SI, when a pollen grain produced in a plant reaches a stigma of the same plant or another plant with a matching allele or genotype, the process of pollen germination, pollen-tube growth, ovule fertilization, or embryo development is inhibited, and consequently no seeds are produced. SI is one of the most important means of preventing inbreeding and promoting the generation of new genotypes in plants and it is considered one of the causes of the spread and success of angiosperms on Earth.

Growing Season
A season is a division of the year marked by changes in weather, ecology, and the amount of daylight. The growing season is that portion of the year in which local conditions (i.e. rainfall, temperature, daylight) permit normal plant growth. While each plant or crop has a specific growing season that depends on its genetic adaptation, growing seasons can generally be grouped into macro-environmental classes. Axial tilt of the Earth inherently affect growing seasons across the globe. Geography Geographic conditions have major impacts on the growing season for any given area. Latitude is one of the major factors in the length of the growing season. The further from the equator one goes, the angle of the Sun gets lower in the sky. Consequently, sunlight is less direct and the low angle of the Sun means that soil takes longer to warm during the spring months, so the growing season begins later. The other factor is altitude, with high elevations having cooler temperatures which short ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Temperate Climate
In geography, the temperate climates of Earth occur in the middle latitudes (approximately 23.5° to 66.5° N/S of the Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates, where such variations are often small; they usually differ only in the amount of precipitation. In temperate climates, not only do latitudinal positions influence temperature changes, but various sea currents, prevailing wind direction, continentality (how large a landmass is) and altitude also shape temperate climates. The Köppen climate classification defines a climate as "temperate" C, when the mean temperature is above but below in the coldest month to account for the persistence of frost. However, some adaptations of Köppen set the minimum at . Continental climates are classified as D and considered to be varieties of temperate climates, ...

Russeting
Russeting or russetting is an abnormality of fruit skin which manifests in russet-colored (brownish) patches that are rougher than healthy skin. It is a common feature in apples and pears. Russeting is typically an undesirable trait, which reduces the storage life of fruits and makes their appearance unattractive to consumers, although some cultivars, so-called russet apples, are appreciated for the feature. Causes In apples and pears, russet results from micro-cracking of the cuticle, the outer epidermal layer of the fruit. The cuticle is a natural waterproof barrier composed of a polymerized cutin matrix embedded with waxes, which protects the fruit from outside stresses, and helps maintain post-harvest preservation. When the cuticle cracks, a corky suberized layer is formed on the fruit skin. Apples are particularly susceptible to russet. Many naturally-occurring varieties exhibit the feature consistently, while other cultivars may develop russet due to environmental stress ...

Triploid
Polyploidy is a condition in which the cells of an organism have more than two paired sets of ( homologous) chromosomes. Most species whose cells have nuclei (eukaryotes) are diploid, meaning they have two complete sets of chromosomes, one from each of two parents; each set contains the same number of chromosomes, and the chromosomes are joined in pairs of homologous chromosomes. However, some organisms are polyploid. Polyploidy is especially common in plants. Most eukaryotes have diploid somatic cells, but produce haploid gametes (eggs and sperm) by meiosis. A monoploid has only one set of chromosomes, and the term is usually only applied to cells or organisms that are normally diploid. Males of bees and other Hymenoptera, for example, are monoploid. Unlike animals, plants and multicellular algae have life cycles with two alternating multicellular generations. The gametophyte generation is haploid, and produces gametes by mitosis; the sporophyte generation is diploid and p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meiji Restoration
The , referred to at the time as the , and also known as the Meiji Renovation, Revolution, Regeneration, Reform, or Renewal, was a political event that restored Imperial House of Japan, imperial rule to Japan in 1868 under Emperor Meiji. Although there were ruling emperors before the Meiji Restoration, the events restored practical power to, and consolidated the political system under, the Emperor of Japan. The Restoration led to enormous changes in Japan's political and social structure and spanned both the late Edo period (often called the Bakumatsu) and the beginning of the Meiji era, during which time Japan rapidly Industrialization, industrialised and adopted Western culture, Western ideas and production methods. The origins of the Restoration lay in economic and political difficulties faced by the Tokugawa shogunate. These problems were compounded by the encroachment of foreign powers in the region which challenged the Tokugawa policy of , specifically the arrival of the Pe ...

Tōhoku Region
The , Northeast region, , or consists of the northeastern portion of Honshu, the largest island of Japan. This traditional region consists of six prefectures (): Akita, Aomori, Fukushima, Iwate, Miyagi, and Yamagata. Tōhoku retains a reputation as a remote, scenic region with a harsh climate. In the 20th century, tourism became a major industry in the Tōhoku region. History Ancient and classical period In mythological times, the area was known as Azuma (, ) and corresponded to the area of Honshu occupied by the native Emishi and Ainu. The area was historically the Dewa and the Michinoku regions, a term first recorded in (654). There is some variation in modern usage of the term "Michinoku". Tōhoku's initial historical settlement occurred between the seventh and ninth centuries, well after Japanese civilization and culture had become firmly established in central and southwestern Japan. The last stronghold of the indigenous Emishi on Honshu and the site of ... [...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 family farm of J. M. Mullins in Clay County, West Virginia, and was locally known as Mullins' Yellow Seedling. Mullins sold the tree and propagation rights to Stark Brothers Nurseries for $5000, which first marketed it as a companion of their Red Delicious in 1914. In 1943, the New York State Agricultural Experiment Station in Geneva, New York developed the Jonagold apple by cross-breeding Golden Delicious and Jonathan (apple), Jonathan trees. The cultivar was officially released in 1968 and went on to become the leading apple cultivar in Europe. According to the USApple Association website, , Golden Delicious, along with its descendent cultivars Gala (apple), Gala, Ginger ...
