Potassium Deficiency (plants)
Potassium deficiency, also known as potash deficiency, is a plant disorder that is most common on light, sandy soils, because potassium ions (K+) are highly soluble and will easily leach from soils without colloids.Datnoff, L.E. et al. ''Mineral Nutrition and Plant Disease''. The American Phytopathological Society, 2007 Potassium deficiency is also common in chalky or peaty soils with a low clay content. It is also found on heavy clays with a soil structure, poor structure. Role of potassium in plants The main role of potassium is to provide the ionic environment for metabolic processes in the cytosol, and as such functions as a regulator of various processes including growth regulation. Plants require potassium ions (K+) for protein synthesis and for the opening and closing of stomata, which is regulated by proton pumps to make surrounding guard cells either Turgor pressure, turgid or flaccid. A deficiency of potassium ions can impair a plant's ability to maintain these proce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tomate Blatt Kalimangel
Kid Abelha was a pop music, pop band from Rio de Janeiro, Brazil, formed by Paula Toller (lead vocals), George Israel (sax, guitar and vocals) and Bruno Fortunato (acoustic and electric guitar). The group has recorded 13 studio albums, 3 live albums and 2 live DVDs. They have created many songs which have entered into Brazilian pop-rock history. The group sold more than 8 million albums worldwide. History A precursor group was formed by drummer Carlos Beni, Pedro Farah and Leoni, called "Chrisma". In 1981, Paula Toller meets Leoni in college, PUC-Rio, they start dating and then she used to visit the band rehearsals. The boys always asked her to join the band, but she denied a lot of times, saying she was too shy, but her constant visits to the rehearsals motivated her to sing. George Israel, otherwise, was seen playing saxophone in Búzios and invited by a friend of Leoni to meet the band. In 1982, with guitarist Beto Martins and United States, American keyboardist Richard Owens t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enzymes
Enzymes () are proteins that act as biological catalysts by accelerating chemical reactions. The molecules upon which enzymes may act are called substrate (chemistry), substrates, and the enzyme converts the substrates into different molecules known as product (chemistry), products. Almost all metabolism, metabolic processes in the cell (biology), cell need enzyme catalysis in order to occur at rates fast enough to sustain life. Metabolic pathways depend upon enzymes to catalyze individual steps. The study of enzymes is called ''enzymology'' and the field of pseudoenzyme, pseudoenzyme analysis recognizes that during evolution, some enzymes have lost the ability to carry out biological catalysis, which is often reflected in their amino acid sequences and unusual 'pseudocatalytic' properties. Enzymes are known to catalyze more than 5,000 biochemical reaction types. Other biocatalysts are Ribozyme, catalytic RNA molecules, called ribozymes. Enzymes' Chemical specificity, specific ...

Sugar Beet
A sugar beet is a plant whose root contains a high concentration of sucrose and which is grown commercially for sugar production. In plant breeding, it is known as the Altissima cultivar group of the common beet (''Beta vulgaris''). Together with other beet cultivars, such as beetroot and chard, it belongs to the subspecies ''Beta vulgaris'' subsp. ''vulgaris.'' Its closest wild relative is the sea beet (''Beta vulgaris'' subsp. ''maritima''). Sugar beets are grown in climates that are too cold for sugar cane. The low sugar content of the beets makes growing them a marginal proposition unless prices are relatively high. In 2020, Russia, the United States, Germany, France and Turkey were the world's five largest sugar beet producers. In 2010–2011, Europe, and North America except Arctic territories failed to supply the overall domestic demand for sugar and were all net importers of sugar. The US harvested of sugar beets in 2008. In 2009, sugar beets accounted for 20% of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raspberry
The raspberry is the edible fruit of a multitude of plant species in the genus ''Rubus'' of the rose family, most of which are in the subgenus '' Idaeobatus''. The name also applies to these plants themselves. Raspberries are perennial with woody stems. World production of raspberries in 2020 was 895,771 tonnes, led by Russia with 20% of the total. Description A raspberry is an aggregate fruit, developing from the numerous distinct carpels of a single flower. What distinguishes the raspberry from its blackberry relatives is whether or not the torus ( receptacle or stem) "picks with" (i.e., stays with) the fruit. When picking a blackberry fruit, the torus stays with the fruit. With a raspberry, the torus remains on the plant, leaving a hollow core in the raspberry fruit. Raspberries are grown for the fresh fruit market and for commercial processing into individually quick frozen (IQF) fruit, purée, juice, or as dried fruit used in a variety of grocery products such as raspb ...

Gooseberry
Gooseberry ( or (American and northern British) or (southern British)) is a common name for many species of ''Ribes'' (which also includes currants), as well as a large number of plants of similar appearance. The berries of those in the genus ''Ribes'' (sometimes placed in the genus ''Grossularia'') are edible and may be green, orange, red, purple, yellow, white, or black. Etymology The ''goose'' in ''gooseberry'' has been mistakenly seen as a corruption of either the Dutch word or the allied German , or of the earlier forms of the French . Alternatively, the word has been connected to the Middle High German ('curl, crisped'), in Latin as . However, the ''Oxford English Dictionary'' takes the more literal derivation from ''goose'' and ''berry'' as probable because "the grounds on which plants and fruits have received names associating them with animals are so often inexplicable that the inappropriateness in the meaning does not necessarily give good grounds for believin ...

Ribes
''Ribes'' is a genus of about 200 known species of flowering plants, most of them native to the temperate regions of the Northern Hemisphere. The various species are known as currants or gooseberries, and some are cultivated for their edible fruit or as ornamental plants. ''Ribes'' is the only genus in the family Grossulariaceae. Description ''Ribes'' species are medium shrublike plants with marked diversity in strikingly diverse flowers and fruit. They have either palmately lobed or compound leaves, and some have thorns. The sepals of the flowers are larger than the petals, and fuse into a tube or saucer shape. The ovary is inferior, maturing into a berry with many seeds. Taxonomy ''Ribes'' is the single genus in the Saxifragales family Grossulariaceae. Although once included in the broader circumscription of Saxifragaceae ''sensu lato'', it is now positioned as a sister group to Saxifragaceae ''sensu stricto''. Subdivision First treated on a worldwide basis in 1907, the in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
