Rice

= **R﻿i﻿﻿﻿c﻿e** **By: Sheldon Walker **  =

**Domestication**:
-Domesticated in south Asia at least 10,000 years ago, and //Oryza glabberima//, domesticated in west Africa between about 1500 and 800 BC. -According to the latest molecular studies, Oryza sativa was domesticated at least twice: //O.// sativa japonica, developed in south China, and //O.// sativa indica, developed in eastern India or Indonesia. Both of these were domesticated from the original plant called Oryza rufipogon. -Rice hasn't changed drastically since it was originally founded, but it produces more now, then it did years ago, due to new pesticides and it's ability to adapt to different environments.. -Apparently rice was founded in the Yangtze river valley, which is the biggest river in Asia. -The Yangtze river valley was the main trade route throughout China.

Yangtze River  ===﻿ === === - Rice is grown in areas of land that receive large amounts of water, be it through rainfall, flooding, or irrigation systems. It needs its water to grow and develop. Thats why it was found along the Yagntzee river. ===

-There are four major categories of rice worldwide: Indica, japonica, aromatic and glutinious.
-Rice is formed from a ripened ovary -Rice has a relationship with the Azolla it's main companion plant due to the nitrogen it releases and blocking out any competing plants. -Rice is the main staple to many countries like China, India, and Indonesia. -Rice has ended famines and helped countries like China thrive, such a high population needs to be fed, and that's done by rice, which takes up 90% of China's agricultural areas. -Rice hasn't changed from it's ancestor very much, ﻿ excpet for ﻿ the varieties it has branched off into. Consider the following in your reflection: How does understanding about this plants and its history relate to your life in a global community? Comment on humans and their control over nature. How has our society's experience of food changed? Provide two questions for further study.
 * Human/Plant relationship**: How has the plant evolved to be of importance to humans? How important is it to our survival/success? How different is today's version of the plant from its ancestor?
 * Reflection:** In a paragraph I want you to describe what you learned and what you wonder about plants and humans.
