Question

Which of the following statement is NOT true about the seed culture of Orchids?

• A. They grow on salt poor medium as mineral requirement is low
• B. Protocorm like structure is formed from the embryo
• C. Seeds are very small and contain little or no food reserve
• D. In vitro germination and development is very slow in Orchids

Hint:

Orchid seeds: - No endosperm - Require special culture - Grow efficiently in vitro

Answer 1

The Correct Option is D

Concept: Orchid seeds are unique and require special conditions for germination, especially in tissue culture.

Step 1: Understand orchid seed characteristics.

• Very small seeds
• Lack endosperm (no food reserve)
• Depend on external nutrients or symbiosis

Step 2: Evaluate statements.

• (A) Correct → Require low mineral salts
• (B) Correct → Protocorm-like structure develops
• (C) Correct → Seeds lack food reserves
• (D) Incorrect → In vitro germination is actually faster and efficient

Step 3: Final conclusion.
Thus, the statement which is NOT true is: \[ \textit{In vitro germination and development is very slow} \]
