Alternanthera Sessilis
''Alternanthera sessilis'' is a flowering plant known by several common names, including sissoo spinach, Brazilian spinach, sessile joyweed and dwarf copperleaf. It is cultivated as a vegetable worldwide. Distribution The plant occurs throughout the tropical and subtropical regions of the Old World. It has been introduced to the southern United States, and its origins in Central and South America are uncertain. This species is classified as a weed in parts of the southern states of the USA. It is usually (but not always especially in areas of high humidity where it can even be a garden weed) found in wet or damp spots. Description This is a perennial herb with prostrate stems, rarely ascending, often rooting at the nodes. Leaves obovate to broadly elliptic, occasionally linear-lanceolate, 1–15 cm long, 0.3–3 cm wide, glabrous to sparsely villous, petioles 1–5 mm long. Flowers in sessile spikes, bract and bracteoles shiny white, 0.7–1.5 mm long, glabr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pasta Sauce
Tomato sauce (also known as ''salsa roja'' in Spanish or ''salsa di pomodoro'' in Italian) can refer to many different sauces made primarily from tomatoes, usually to be served as part of a dish (food), dish, rather than as a condiment. Tomato sauces are common for meat and vegetables, but they are perhaps best known as bases for sauces for Mexican Salsa (sauce), salsas and Italian pasta dishes. Tomatoes have a rich flavor, high water content, soft flesh which breaks down easily, and the right composition to thicken into a sauce when stewed without the need of thickeners such as roux or masa. All of these qualities make them ideal for simple and appealing sauces. In countries such as the United Kingdom, India, Australia, New Zealand, and South Africa, the term ''tomato sauce'' is used to describe a condiment similar to what Americans call ketchup, tomato ketchup. In some of these countries, both terms are used for the condiment. History The first European person to write about ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plant Propagation
Plant propagation is the process by which new plants grow from a variety of sources: seeds, cuttings, and other plant parts. Plant propagation can also refer to the man-made or natural dispersal of seeds. Propagation typically occurs as a step in the overall cycle of plant growth. For seeds, it happens after ripening and dispersal; for vegetative parts, it happens after detachment or pruning; for asexually-reproducing plants, such as strawberry, it happens as the new plant develops from existing parts. Plant propagation can be divided into four basic types: sexual, asexual (vegetative), layering, and grafting. Countless plants are propagated each day in horticulture and agriculture. The materials commonly used for plant propagation are seeds and cuttings. Sexual propagation Seeds and spores can be used for reproduction (e.g. sowing). Seeds are typically produced from sexual reproduction within a species because genetic recombination has occurred. A plant grown from seeds may ...

Living Mulch
In agriculture, a living mulch is a cover crop interplanted or undersown with a main crop, and intended to serve the purposes of a mulch, such as weed suppression and regulation of soil temperature. Living mulches grow for a long time with the main crops, whereas cover crops are incorporated into the soil or killed with herbicides. Other benefits of mulches are slowing the growth of weeds, and protecting soil from water and wind erosion. Some living mulches were found to increase populations of the natural enemies of crop pests.Hartwig N.L., H.. Ammon 2002 Cover crops and living mulches Weed Sci. 50: 688-699 Legumes used as living mulches also provide nitrogen fixation, reducing the need for fertilizer. Benefits When cover crops are turned over into the soil, they contribute nutrients to the main crop so that less chemical fertilizer is required.Brophy L. S., G. H. Heichel and M.P. Russelle. 1987 Nitrogen transfer from forage legumes to grass in a systematic planting design C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...

Node (botany)
A stem is one of two main structural axes of a vascular plant, the other being the root. It supports leaf, leaves, flowers and fruits, transports water and dissolved substances between the roots and the shoots in the xylem and phloem, stores nutrients, and produces new living tissue. The stem can also be called halm or haulm. The stem is normally divided into nodes and internodes: * The nodes hold one or more leaves, as well as buds which can grow into branches (with leaf, leaves, conifer cones, or inflorescence, flowers). Adventitious roots may also be produced from the nodes. * The internodes distance one node from another. The term "shoots" is often confused with "stems"; "shoots" generally refers to new fresh plant growth including both stems and other structures like leaves or flowers. In most plants stems are located above the soil surface but some plants have underground stems. Stems have four main functions which are: * Support for and the elevation of leaves, flower ...

Cultivar
A cultivar is a type of cultivated plant that people have selected for desired traits and when propagated retain those traits. Methods used to propagate cultivars include: division, root and stem cuttings, offsets, grafting, tissue culture, or carefully controlled seed production. Most cultivars arise from purposeful human manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in ''Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants that share the unique characteristics that define the cultivar. was coined as a term meaning "cultivated variety ...

Kajal
Kohl ( ar, كُحْل, kuḥl), kajal or kajol is an ancient eye cosmetic, traditionally made by grinding stibnite (Sb2S3) for use similar to that of charcoal in mascara. It is widely used in the Middle East, Caucasus and North Africa, South Asia, West Africa, and the Horn of Africa as eyeliner to contour and/or darken the eyelids and as mascara for the eyelashes. It is worn mostly by women, but also by some men and children. The content of kohl and various ways to prepare it differ based on tradition and country. Several studies have questioned the safety of kohl due to the dangers of lead poisoning. Name The Arabic name formed the Arabic root ''k-ḥ-l, “to apply kohl”''. Transliteration variants of Arabic dialectal pronunciation include ''kohl'' or ''kuhl''. The Arabic word cognates with Syriac-Aramaic word ܟܘܚܠܐ/כוחלא ''kuḥla''. Both words derived from Akkadian 𒎎𒋆𒁉𒍣𒁕 ''guẖlu(m)'' meaning stibium. The English word ''alcohol'' is a loan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stir Frying
Stir frying () is a cooking technique in which ingredients are fried in a small amount of very hot oil while being stirred or tossed in a wok. The technique originated in China and in recent centuries has spread into other parts of Asia and the West. It is similar to sautéing in Western cooking technique. Scholars think that wok (or pan) frying may have been used as early as the Han dynasty (206 B.C. – 220 A.D.) for drying grain, not for cooking, but it was not until the Ming dynasty (1368–1644) that the wok reached its modern shape and allowed quick cooking in hot oil. Well into the 20th century, while only restaurants and affluent families could afford the oil and fuel needed for stir fry, the most widely used cooking techniques remained boiling and steaming. Stir fry cooking came to predominate over the course of the century as more people could afford oil and fuel, and in the West spread beyond Chinese communities. Stir frying and Chinese food have been recommend ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
