Indian Lotus
''Nelumbo nucifera'', also known as the pink lotus, sacred lotus, Indian lotus, or simply lotus, is one of two extant species of aquatic plant in the family Nelumbonaceae. It is sometimes colloquially called a water lily, though this more often refers to members of the family Nymphaeaceae. The lotus belongs in the order Proteales. Lotus plants are adapted to grow in the flood plains of slow-moving rivers and delta areas. Stands of lotus drop hundreds of thousands of seeds every year to the bottom of the pond. While some sprout immediately and most are eaten by wildlife, the remaining seeds can remain dormant for an extensive period of time as the pond silts in and dries out. During flood conditions, sediments containing these seeds are broken open, and the dormant seeds rehydrate and begin a new lotus colony. It is cultivated in nutrient-rich, loamy, and often flooded soils, requiring warm temperatures and specific planting depths, with propagation via rhizomes, seeds, or ...

Joseph Gaertner
Joseph Gaertner (12 March 1732 – 14 July 1791) was a German botanist, best known for his work on seeds, ''De Fructibus et Seminibus Plantarum'' (1788-1792). Biography He was born in Calw, and studied in Göttingen under Albrecht von Haller. He was primarily a naturalist, but also worked at physics and zoology. He travelled extensively to visit other naturalists. He was professor of anatomy in Tübingen in 1760, and was appointed professor of botany at St Petersburg in 1768, but returned to Calw in 1770. Gaertner made back cross to convert one species into another. Back cross increases nuclear gene frequency His observations were: 1. Dominance of traits 2. Equal contribution of male and female to the progeny 3. No variation in F1 (first generation of descendants) 4. Large variation in F2 (second generation of descendants) including parental and intermediate types 5. Some of F2 plants had entirely new traits but he was unable to give possible explanation for observed dat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agriculture
Agriculture encompasses crop and livestock production, aquaculture, and forestry for food and non-food products. Agriculture was a key factor in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in the cities. While humans started gathering grains at least 105,000 years ago, nascent farmers only began planting them around 11,500 years ago. Sheep, goats, pigs, and cattle were domesticated around 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. In the 20th century, industrial agriculture based on large-scale monocultures came to dominate agricultural output. , small farms produce about one-third of the world's food, but large farms are prevalent. The largest 1% of farms in the world are greater than and operate more than 70% of the world's farmland. Nearly 40% of agricultural land is found on farms larger than . However, five of every six farm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chinese Culture
Chinese culture () is one of the Cradle of civilization#Ancient China, world's earliest cultures, said to originate five thousand years ago. The culture prevails across a large geographical region in East Asia called the Sinosphere as a whole and is extremely diverse, with customs and traditions varying greatly between regions. The terms 'China' and the geographical landmass of 'China' have shifted across the centuries, before the name 'China' became commonplace. Chinese civilization is historically considered a dominant culture of East Asia. Chinese culture exerted profound influence on the philosophy, customs, politics, and traditions of Asia.

Ismailism
Ismailism () is a branch of Shia Islam. The Isma'ili () get their name from their acceptance of Imam Isma'il ibn Jafar as the appointed spiritual successor ( imām) to Ja'far al-Sadiq, wherein they differ from the Twelver Shia, who accept Musa al-Kazim, the younger brother of Isma'il, as the true Imām. After the death of Muhammad ibn Isma'il in the 8th century CE, the teachings of Ismailism further transformed into the belief system as it is known today, with an explicit concentration on the deeper, esoteric meaning () of the Islamic religion. With the eventual development of Usulism and Akhbarism into the more literalistic () oriented, Shia Islam developed into two separate directions: the metaphorical Ismaili, Alevi, Bektashi, Alian, and Alawite groups focusing on the mystical path and nature of God, along with the "Imam of the Time" representing the manifestation of esoteric truth and intelligible divine reality, with the more literalistic Usuli and Akhbari groups ...

Jainism
Jainism ( ), also known as Jain Dharma, is an Indian religions, Indian religion whose three main pillars are nonviolence (), asceticism (), and a rejection of all simplistic and one-sided views of truth and reality (). Jainism traces its spiritual ideas and history through the succession of twenty-four , supreme preachers of ''dharma''. The first in the current time cycle is Rishabhadeva, who tradition holds lived millions of years ago; the 23rd is Parshvanatha, traditionally dated to the 9th century Common Era, BCE; and the 24th is Mahāvīra, Mahavira, who lived . Jainism is considered an eternal ''dharma'' with the guiding every time cycle of the Jain cosmology, cosmology. Central to understanding Jain philosophy is the concept of ''bhedavijñāna'', or the clear distinction in the nature of the soul and non-soul entities. This principle underscores the innate purity and potential for liberation within every Jīva (Jainism), soul, distinct from the physical and menta ...

Rhizomes
In botany and dendrology, a rhizome ( ) is a modified subterranean plant stem that sends out roots and shoots from its nodes. Rhizomes are also called creeping rootstalks or just rootstalks. Rhizomes develop from axillary buds and grow horizontally. The rhizome also retains the ability to allow new shoots to grow upwards. A rhizome is the main stem of the plant that runs typically underground and horizontally to the soil surface. Rhizomes have nodes and internodes and auxiliary buds. Roots do not have nodes and internodes and have a root cap terminating their ends. In general, rhizomes have short internodes, send out roots from the bottom of the nodes, and generate new upward-growing shoots from the top of the nodes. A stolon is similar to a rhizome, but stolon sprouts from an existing stem having long internodes and generating new shoots at the ends, they are often also called runners such as in the strawberry plant. A stem tuber is a thickened part of a rhizome or sto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seeds
In botany, a seed is a plant structure containing an embryo and stored nutrients in a protective coat called a ''testa''. More generally, the term "seed" means anything that can be sown, which may include seed and husk or tuber. Seeds are the product of the ripened ovule, after the embryo sac is fertilized by sperm from pollen, forming a zygote. The embryo within a seed develops from the zygote and grows within the mother plant to a certain size before growth is halted. The formation of the seed is the defining part of the process of reproduction in seed plants (spermatophytes). Other plants such as ferns, mosses and liverworts, do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological niches on land, from forests to grasslands both in hot and cold climates. In the flowering plants, the ovary ripens into a fruit which contains the seed and serves to disseminate it. Many structures commonly referred to as "seeds" are actuall ...

Flowers
Flowers, also known as blooms and blossoms, are the reproductive structures of flowering plants ( angiosperms). Typically, they are structured in four circular levels, called whorls, around the end of a stalk. These whorls include: calyx, modified leaves; corolla, the petals; androecium, the male reproductive unit consisting of stamens and pollen; and gynoecium, the female part, containing style and stigma, which receives the pollen at the tip of the style, and ovary, which contains the ovules. When flowers are arranged in groups, they are known collectively as inflorescences. Floral growth originates at stem tips and is controlled by MADS-box genes. In most plant species flowers are heterosporous, and so can produce sex cells of both sexes. Pollination mediates the transport of pollen to the ovules in the ovaries, to facilitate sexual reproduction. It can occur between different plants, as in cross-pollination, or between flowers on the same plant or even the same flowe ...

Asia
Asia ( , ) is the largest continent in the world by both land area and population. It covers an area of more than 44 million square kilometres, about 30% of Earth's total land area and 8% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilisations. Its 4.7 billion people constitute roughly 60% of the world's population. Asia shares the landmass of Eurasia with Europe, and of Afro-Eurasia with both Europe and Africa. In general terms, it is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a social constructionism, historical and cultural construct, as there is no clear physical and geographical separation between them. A commonly accepted division places Asia to the east of the Suez Canal separating it from Africa; and to the east of the Turkish straits, the Ural Mountains an ...

Buddhism
Buddhism, also known as Buddhadharma and Dharmavinaya, is an Indian religion and List of philosophies, philosophical tradition based on Pre-sectarian Buddhism, teachings attributed to the Buddha, a wandering teacher who lived in the 6th or 5th century Before the Common Era, BCE. It is the Major religious groups, world's fourth-largest religion, with about 500 million followers, known as Buddhists, who comprise four percent of the global population. It arose in the eastern Gangetic plain as a movement in the 5th century BCE, and gradually spread throughout much of Asia. Buddhism has subsequently played a major role in Asian culture and spirituality, eventually spreading to Western world, the West in the 20th century. According to tradition, the Buddha instructed his followers in a path of bhavana, development which leads to Enlightenment in Buddhism, awakening and moksha, full liberation from ''Duḥkha, dukkha'' (). He regarded this path as a Middle Way between extremes su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
