Question

Arrange the growth stages of wheat from germination to maturity. A. Booting stage, B. Crown root initiation, C. Anthesis, D. Grain filling.

• A. B, A, D, C
• B. B, A, C, D
• C. A, B, D, C
• D. C, A, B, D

Hint:

In wheat, crown root initiation occurs early, followed by booting, anthesis and grain filling.

Answer 1

The Correct Option is B

Concept:
Wheat growth follows a definite sequence from germination to maturity.

Step 1: Crown root initiation.
After germination, crown roots start developing. This is an early vegetative growth stage. \[ \text{First step}=B \]

Step 2: Booting stage.
Booting stage occurs later when the developing ear is enclosed within the leaf sheath. \[ \text{Second step}=A \]

Step 3: Anthesis.
Anthesis means flowering. It occurs after booting and heading. \[ \text{Third step}=C \]

Step 4: Grain filling.
After anthesis and fertilization, grain filling occurs. \[ \text{Fourth step}=D \] Therefore, the correct sequence is: \[ B,A,C,D \] \[ \therefore \text{Correct Answer is (B)} \]
