tailieunhanh - Detection of actual and assessment of potential plantations in Lao PDR using GIS and remote sensing technologies

In Southeast Asia there have been found a lot of rubber-bearing plants. Most of them are members of the one family, Apocynaceae, but there are also some important species from other families, like Ficus elastica Roxb. and Bleekrodea tonkinensis Dub. & Eber., which both belongs to the family Moraceae. The first seeds for the cultivation of the rubber were sent to Asia, Sri Lanka, in 1876, but these first attempts to grow the rubber trees (Hevea brasiliensis Muell. Arg.) were not successful. It was not until 1877 when 22 rubber trees were plated in Singapore.
