The oldest viable seed that has grown into a full plant was a roughly 2,000-year-old Judean date palm seed, recovered during excavations at Herod the Great 's palace on Masada. It had been preserved in a cool, dry place, not by freezing. It was germinated in 2005. [3][4][5][6]
Norman C. Deno. Norman C. Deno (February 15, 1921 – September 22, 2017) was an American chemist and plant scientist. He was a professor of chemistry at Penn State University and is known as one of the foremost researchers in seed germination theory. He researched the biochemical reactions that underlie the germination of all seeds, performing ...
Germination is the process by which an organism grows from a seed or spore. The term is applied to the sprouting of a seedling from a seed of an angiosperm or gymnosperm, the growth of a sporeling from a spore, such as the spores of fungi, ferns, bacteria, and the growth of the pollen tube from the pollen grain of a seed plant.
Funeral pyre in Ubud, Bali.Cremation is the preferred method of disposal of the dead in Buddhism. [1]Cremation rates vary widely across the world. [2] As of 2019, international statistics report that countries with large Buddhist and Hindu populations like Bhutan, Cambodia, Hong Kong, Japan, Myanmar, Nepal, Tibet, Sri Lanka, South Korea, Thailand and India have a cremation rate ranging from 80 ...
Plant propagation is the process by which new plants grow from various sources, including seeds, cuttings, and other plant parts. Plant propagation can refer to both man-made and natural processes. Propagation typically occurs as a step in the overall cycle of plant growth. For seeds, it happens after ripening and dispersal; for vegetative ...
Vivipary. Watsonia meriana, near the end of flowering, has cormlets that eventually drop and root. Red mangrove seeds germinate while still on the parent tree. In plants, vivipary occurs when seeds or embryos begin to develop before they detach from the parent. Plants such as some Iridaceae and Agavoideae grow cormlets in the axils of their ...

Seeds of many trees, shrubs and perennials require these conditions before germination will ensue. [citation needed] In the wild, seed dormancy is usually overcome by the seed spending time in the ground through a winter period and having its hard seed coat softened by frost and weathering action. By doing so the seed is undergoing a natural ...
