Schisandra Chinensis
''Schisandra chinensis'' (common name: magnolia-vine, Chinese magnolia-vine, schisandra), whose fruit is called magnolia berry or five-flavor-fruit (from Chinese 五味子 ''wǔwèizi''), is a vine plant native to forests of Northern China, the Russian Far East and Korea. Wild varieties are also found in Japan. It is hardy in USDA Zone 4. The fruits are red berries in dense clusters around long. Etymology, common names, and taxonomy The genus ''Schisandra'' was first published by André Michaux in 1803, the name deriving from the Greek words ''schizein'' ('to split') and ''andros'' ('man'), referring to the separate anther cells on the stamens. In the 21st century, ''Schisandra chinensis'' belongs to the family of Schisandraceae. In earlier years, it was assumed that the species belonged to the family of Magnoliaceae, hence the name ''Chinese magnolia-vine''. However, many differences in plant phenology between Schisandra and members of Magnoliaceae led to the formatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Manchuria
Manchuria is an exonym (derived from the endo demonym " Manchu") for a historical and geographic region in Northeast Asia encompassing the entirety of present-day Northeast China (Inner Manchuria) and parts of the Russian Far East (Outer Manchuria). Its meaning may vary depending on the context: * Historical polities and geographical regions usually referred to as Manchuria: ** The Later Jin (1616–1636), the Manchu-led dynasty which renamed itself from "Jin" to "Qing", and the ethnicity from "Jurchen" to "Manchu" in 1636 ** the subsequent duration of the Qing dynasty prior to its conquest of China proper (1644) ** the northeastern region of Qing dynasty China, the homeland of Manchus, known as "Guandong" or "Guanwai" during the Qing dynasty ** The region of Northeast Asia that served as the historical homeland of the Jurchens and later their descendants Manchus ***Qing control of Dauria (the region north of the Amur River, but in its watershed) was contested in 1643 when ...

Paraquat
Paraquat (trivial name; ), or ''N'',''N''′-dimethyl-4,4′-bipyridinium dichloride (systematic name), also known as methyl viologen, is an organic compound with the chemical formula C6H7N)2l2. It is classified as a viologen, a family of redox-active heterocycles of similar structure. This salt is one of the most widely used herbicides. It is quick-acting and non-selective, killing green plant tissue on contact. It is also toxic (lethal) to human beings and animals due to its redox Redox (reduction–oxidation, , ) is a type of chemical reaction in which the oxidation states of substrate (chemistry), substrate change.

Sun Scald
Sun scald is the freezing of bark following high temperatures in the winter season, resulting in permanent visible damage to bark. Fruits may also be damaged. In the northern hemisphere, it is also called southwest injury. Causes The reason the sun can cause so much damage to trees is because of dormancy. When a tree is dormant in the winter it can be reactivated by warm weather. In the northern woods trees are exposed to the most sunlight and heat on the southwest facing side, so this side is heated during warm sunny winter days (in the afternoon, that's why westwards) to the point that it can be awoken from dormancy. The temperature required to wake up a tree depends on plant species and length of day, but it is typically just above freezing.( Dormancy In Plants: A Process For Survival) Once active, the cells on the southwest side of the plant are unable to return to dormancy by nightfall, at which time the temperature returns to levels capable of killing active cells.

Downy Mildew
Downy mildew refers to any of several types of oomycete microbes that are obligate parasites of plants. Downy mildews exclusively belong to the Peronosporaceae family. In commercial agriculture, they are a particular problem for growers of crucifers, grapes and vegetables that grow on vines. The prime example is ''Peronospora farinosa'' featured in NCBI-Taxonomy and HYP3. This pathogen does not produce survival structures in the northern states of the United States, and overwinters as live mildew colonies in Gulf Coast states. It progresses northward with cucurbit production each spring. Yield loss associated with downy mildew is most likely related to soft rots that occur after plant canopies collapse and sunburn occurs on fruit. Cucurbit downy mildew only affects leaves of cucurbit plants. Symptoms Initial symptoms include large, angular or blocky, yellow areas visible on the upper surface. As lesions mature, they expand rapidly and turn brown. The under surface of infected ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Powdery Mildew
Powdery mildew is a fungal disease that affects a wide range of plants. Powdery mildew diseases are caused by many different species of ascomycete fungi in the order Erysiphales. Powdery mildew is one of the easier plant diseases to identify, as its symptoms are quite distinctive. Infected plants display white powdery spots on the leaves and stems. 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 thrive in a greenhouse setting. In an agricultural or horticultural setting, the pathogen can be controlle ...

Alternaria Tenuissima
''Alternaria tenuissima'' is a saprophyte, saprophytic fungi, fungus and opportunistic plant pathogen. It is Cosmopolitan distribution, cosmopolitan in distribution, and can colonize a wide range of plant hosts. Colonies of ''A. tenuissima'' produce chains on agar growth media. The fungus often forms concentric ring patterns on infected plant leaves. This species produces the allergen Alt a 1, one of the most important outdoor seasonal fungal allergens associated with allergy and asthma provocation. In rare circumstances, this species is also known to infect immunosuppressed humans and animals. Growth and morphology Unlike many other species of ''Alternaria'', the conidiophores of ''A. tenuissima'' can develop in darkness after the colony has been exposed to light even very briefly; however its growth is more robust with longer periods of light exposure. After 5–7 days in culture, colonies of ''A. tenuissima'' reach a diameter of 5 cm on Plate count agar, PCA or V-8 agar (v ...

Pseudaulacaspis Pentagona
''Pseudaulacaspis pentagona'', the white peach scale or mulberry scale, is a species of armoured scale insect in the family Diaspididae. This scale infests over 100 different genera of plants including many fruit trees and ornamentals. Description The adult female insect is up to in length. The soft yellow body is concealed under a roughly circular, whitish test with a yellowish-brown off-centre spot (this is the exuviae or shed skins of the last two nymphal moults). Males are concealed under whitish, felted, elongated oval tests with yellowish spots at one end; sometimes many males will accumulate in one area, covering the bark and looking like snow. Mature males have no mouthparts but have wings and seek out females, while mature females do not have wings and remain permanently in one place. Distribution ''Pseudaulacaspis pentagona'' is native to eastern Asia but has been accidentally introduced into many other warm and temperate parts of the world. In Europe, it was first de ...

Botrytis Cinerea
''Botrytis cinerea'' is a necrotrophic fungus that affects many plant species, although its most notable hosts may be wine grapes. In viticulture, it is commonly known as "botrytis bunch rot"; in horticulture, it is usually called "grey mould" or "gray mold". The fungus gives rise to two different kinds of infections on grapes. The first, grey rot, is the result of consistently wet or humid conditions, and typically results in the loss of the affected bunches. The second, noble rot, occurs when drier conditions follow wetter, and can result in distinctive sweet dessert wines, such as Sauternes (wine), Sauternes or the Aszú of Tokaji/Grasă de Cotnari. The species name ''Botrytis cinerea'' is derived from the Latin for "grapes like ashes"; although poetic, the "grapes" refers to the bunching of the fungal spores on their Conidium, conidiophores, and "ashes" just refers to the greyish colour of the spores ''en masse''. The fungus is usually referred to by its anamorph (asexual form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
