Q. With reference Rubber, consider the following statements;
1.Lateritic type, alluvial, sedimentary types, and non lateritic red soils are best for the growth of rubber trees.
2.Synthetic rubber is preferred over natural rubber for its high tensile strength and vibration dampening properties, tear resistance.
3.Hevea brasiliensis is the most important rubber tree.
Which of the statements given above is/are correct?
Answer: C
Notes:
Statement 1 is correct: Lateritic type, alluvial, sedimentary types, and non lateritic red soils are best for the growth of rubber trees.
Statement 2 is incorrect: Natural rubber is preferred over synthetic rubber due to its high tensile strength and vibration dampening properties, along with tear resistance.
Statement 3 is correct: Natural rubber comes from various sources, the most common being the Pará rubber tree (Hevea brasiliensis). It grows well under cultivation and yields latex for several years.
The vines in the genus Landolphia yield the Congo rubber. These vines cannot be grown in cultivation and this led to large-scale exploitation of the wild plants in Congo.
