Plantas Tropicales Subexplotadas con Valor Economico Prometedor (Under-Exploited Tropical Plants with Promising Economic Value).

PB298481

Publication Date	1975
Page Count	197
Abstract	The report is on plants that show promise for improving the quality of life in tropical areas. The report aims to provide a brief introduction to the plants selected. It is neither a textbook nor a comprehensive study of tropical botany. The report does not detail how to introduce the plants to new areas. Readers should appreciate that achieving this goal may be complex and difficult. Many plants discussed in this report have defied dissemination (or domestication) for a century or more. Plant introduction cannot be divorced from plant management; a lack of horticultural knowledge or experience will frequently cause a plant introduction to fail. Differences in elevation, soil type, temperature, day length, and rainfall present other complications. Sometimes newly introduced plants prove to be too aggressive and become weeds. Even if all these problems are overcome, the plant will be successful only if a market exists or can be created.
