Rice is the seed of the grass species Oryza sativa (Asian rice)—or, much less commonly, Oryza glaberrima (African rice). Asian rice was domesticated in China some 13,500 to 8,200 years ago; African rice was domesticated in Africa about 3,000 years ago.
6 days ago · Rice, edible starchy cereal grain and the plant by which it is produced. Roughly one-half of the world population, including virtually all of East and Southeast Asia, is wholly dependent upon rice as a staple food; 95 percent of the world’s rice crop is eaten by humans.
The history of rice cultivation is an interdisciplinary subject that studies archaeological and documentary evidence to explain how rice was first domesticated and cultivated by humans, the spread of cultivation to different regions of the planet, and the technological changes that have impacted cultivation over time.
Jul 3, 2019 · By 6000–3500 BCE, rice and other Neolithic lifestyle changes were spread throughout southern China. Rice reached Southeast Asia into Vietnam and Thailand (Hoabinhian period) by 3000–2000 BCE.
Morphology. Rice has the following three main developmental phases: the vegetative phase (from germination to panicle initiation), the reproductive phase (from panicle initiation to flowering), and the ripening phase (from flowering to maturity).
Archaeologists and botanists have long debated the origins of rice. For many archaeologists who focus on East Asia or Southeast Asia, it has long appeared that rice agriculture began in South-central China, somewhere along the Yangzte river, and spread from there southwards and to northeast towards Korea and Japan.
Rice has been studied in great detail by botanists and geneticists unravelling a complicated history which is still subject to disagreement. Divergent views mainly focus on the origins of domesticated rice.
Jan 4, 2012 · Rice can be inferred to have entered cultivation on two pathways from wild ecology and human use. The wild progenitors of Asian rice are well-known to include Oryza rufipogon sensu stricto and Oryza nivara, which are native to South and Southeast Asia, extending northwards into Southern China.
As far back as 2500 B.C. rice has been documented in the history books as a source of food and for tradition as well. Beginning in China and the surrounding areas, its cultivation spread throughout Sri Lanka, and India. It was then passed onto Greece and areas of the Mediterranean.
Sep 25, 2021 · In this article, we discuss the piecemeal, but growing, archaeobotanical data for rice in West Asia. We also integrate written sources, linguistic data, and ethnohistoric analogies, in order to better understand the adoption of rice outside its regions of origin.
