Rubber tree plantation. Natural rubber is produced by many New World plants,the most important of which is the rubber tree,Hevea brasiliensis. Raw rubber is obtained from a milky latex exuded by the tree in response to injury; exactly why the latex is produced is not known. Tapping involves scoring a spiral cut through the bark. The latex flows slowly out and drains into a collecting cup. A single tree can yield up to 30g from a cut before the flow stops. Native to Brazil,the rubber tree was introduced in the early 20th century to Southeast Asia,where most of the world's rubber is now produced. Photographed in Thailand | |
