Question

White jute is obtained from:

• A. Corchorus olitorius
• B. Corchorus capsularis
• C. Cocus nucifera
• D. Crotalaria juncea

Hint:

For economic botany questions, link the common name of the product (e.g., White Jute, Tossa Jute, Cotton, Coir) to its specific botanical source ({Corchorus capsularis}, {Corchorus olitorius}, {Gossypium} spp., {Cocus nucifera}).

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
The question asks for the botanical source of "White jute," a commercially important plant fiber. This requires knowledge of economic botany.
Step 2: Detailed Explanation:
Jute is one of the most important natural fibers, obtained from the stem (bast fiber) of plants belonging to the genus {Corchorus}. There are two main cultivated species:

{Corchorus capsularis:} This species is commonly known as White Jute. It is characterized by its round seed pods ('capsularis' refers to the capsule). The fiber is lighter in color.

{Corchorus olitorius:} This species is known as Tossa Jute or Nalta Jute. It has long, cylindrical seed pods. Its fiber is generally stronger, softer, and more lustrous but can be more brownish.

Let's look at the other options:

{Cocus nucifera:} This is the coconut palm. The fiber obtained from its husk is called coir, not jute.

{Crotalaria juncea:} This plant is known as Sunn hemp, which is another important source of bast fiber, but it is not jute.

Step 3: Final Answer:
Based on the common names associated with the species, White jute is obtained from {Corchorus capsularis}.
