Question:
Which of the following nutrient is related with deficiency symptoms like discoloration of leaf buds, breaking and dropping of buds?
Which of the following nutrient is related with deficiency symptoms like discoloration of leaf buds, breaking and dropping of buds?
Show Hint
Look for terms like "meristem death", "cracked stem", "brittleness", or "bud drop" in exams; these are classic diagnostics of Boron deficiency.

The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Essential plant nutrients are required for specific physiological and structural functions, and their lack manifests as characteristic localized deficiency symptoms.
Step 2: Detailed Explanation:
Boron is essential for cell wall synthesis, sugar translocation, pollen tube growth, and active cell division at growing vegetative points.
Because boron is highly immobile within the plant, deficiency symptoms first appear at the growing tips (apical meristems).
Deficiency causes structural brittleness, resulting in the discoloration of leaf buds, extreme brittleness (breaking), and premature dropping of buds and flowers.
Step 3: Final Answer:
Thus, the correct nutrient associated with these symptoms is Boron.
